Allergies In Adolescents

Allergies may be seen as an nonstandard reaction by a body to something that is harmless. In essence, it is a mistake. The body’s immune system has mis-identified a substance as an enemy, whereas it is really friendly or at least neutral. This is not the fault of that substance.

The substance that is the cause of the allergy is known as an allergen. Not everyone who has an allergy has an allergy to the same allergen, because not everyone’s body makes the same errors.

Potentially anything can be an allergen to somebody and probably is. My uncle is allergic to cotton wool but not to cotton. However, the most common allergens are dust, pollen, pet hairs, medicine, cosmetics and washing powder.

It seems that when the body comes across something that it distrusts, it produces certain chemicals to protect itself. One of these is histamine, which can have an adverse impact on the respiratory system, the digestive system and or the skin.

The body then ‘remembers’ that this safeguard worked because the substance did not win the battle and so reacts in the same manner every time it encounters the substance in the future. An allergy is born, even though the substance was not a threat in the first place.

Not everybody who is allergic to the same substance reacts in the same manner. If you have two people who are allergic to dust, one might get a runny nose whereas the other might suffer something comparable to an asthma attack.

Most allergens cause quite mild reactions, but some can kill. Bee stings and peanuts may kill those who are allergic to them.

Because allergies are a function of the immune system, juveniles are more affected than older people. This is because the immune system of younger people ’still has a lot to learn’. Most allergies wear off as the body becomes more ‘educated’. However, some allergens produce worrying reactions in young people like asthma and eczema.

One of the most common allergies is caused by dust and dust mites. Much of household dust is the dead skin of insects, mites and us humans. This dead skin can be microscopic to quite ‘large’, but cause trouble with individuals when they are inhaled.

Dust mites also live in each bed, eating our dead skin. The larger ones are just about visible by most people at 0.4 mm in length. However, baby dust mites (nymphs) are obviously a lot smaller.

People are not normally allergic to the dust mites themselves but to their faeces and the stomach enzymes that are still present in those faeces. An allergenic mattress cover and pillow covers can help here.

Why some bodies mistake friendly to neutral substances as enemies is not completely understood, but the two most common suggestions are heredity and over-hygiene. There is lots of evidence to show that allergies run in families.

it is also thought that if a child grows up in a sterile environment, it is not being gradually exposed to substances that other people become used to. This is because we decontaminate our houses, schools and offices too well.

How To Hold Mosquitoes At Bay

If you like to sit outdoors in the summer, you almost certainly have a bit of a garden, patio or deck that you like to relax on of a summer’s evening. With a few flowers for colour and perfume, it makes an ideal location to relax. Add a water feature and a cold drink and I am in my element.

That is until five or six o’ clock, at which time the light begins to fade and the mosquitoes come out. They spoil it for me or at least they used to until I found neat little tricks to keep the mosquitoes at bay – out of my yard and into someone else’s. Not that I wish mosquitoes on my friends, but they will go somewhere else, if they do not come to me.

The first thing to do is learn a bit concerning the mosquito. Mosquitoes are not really very strong fliers and they are easily injured and easily blown off course. Therefore, most of the mosquitoes you meet in your garden were born there. Some individuals say tht mosquitoes do not fly over a couple of metres from where they were hatched.

They like to lay their eggs in still water and it need not be that much. Millions of mosquitoes are born in still water that collects in the leaves of living plants. Now, I am not recommending that you cut all your plants down, but you did ought to clean up any old junk in the garden that can retain water.

You can fill in holes and indentations in paths, stow away watering cans and unused flower pots, clean blocked gutters, clear away fallen leaves and maybe think about the flowers that you are purchasing next time you are in the garden centre. If you have a water feature, make certain that there are fish in it that eat insects – some do not.

The next thing to do is find out which plants mosquitoes do not like and they do have their preferences, the same as we do. Mosquitoes hate anything that reminds them of lemons. So, you can plant, lemon balm, citronella, lemon trees, lemon grass and anything else that smells like lemons.

If the plants can not quite produce enough lemon smell some evenings, you can help them with lemon-scented candles or citronella oil rubbed straight onto your skin. It is a perfectly natural oil, so ought to not injure you, your kids or your pets. Dogs suffer from mosquitoes as much as we do.

As mentioned above, mosquitoes are not robust fliers, so a good fan, normally kills hundreds of them a night by blowing them against walls and the fan’s blades. A favourite of mine on a bad night, is a mosquito trap.

One that has highly-charged electrical wires behind an attractive ultra-violet light, the sound of them crackling away on the electrified wire is very enjoyable and highly effective

One mosquito trap can clear a whole garden, but my all-time favourite is the tennis racquet type bug-zapper, the one that looks like a child’s tennis racquet. Anything that gets through your defences, is a certain gonner, if you have a racquet bug zapper

How To Get Bed Bugs Out Of Your Clothes

You cannot tell where bed bugs are living; you cannot even guess, just by looking at a building. You could be sitting in a chair in a posh hotel waiting for someone to come down or you could be having tea at a friend’s house and you are equally as likely to pick up a bed bug.

The developed Western world has not been through this sort of situation for about sixty years. However, since 1995, bed bugs have been increasing practically unbridled and we are approaching the situation people were living in before the Second World War. That is a very sad state of affairs indeed.

Particularly when you appreciate that before the war, you could lay a little poison down and kill them. These days, you cannot, because some bedbugs have become resistant to a lot of the insecticides normally available to family households. So, in one way we are worse off than we were 60 years ago and unless something comes to our aid, it will only get worse.

Although bedbugs wreak most mayhem in a bed, that is not normally where people get them from. They also reside in the folds of fabric in the seats of buses, trains, taxis, hotel rooms, restaurants and even airplanes. However, bedbugs are not taken home stuck to your skin like a flea or a tick.

Rather they will creep into a hem or a pocket or under a collar, drawn by your body heat or breath and either go to sleep or lay eggs. A female can lay 300 eggs in a single day – not a great deal in insect terms, but do you want 301 bedbugs in your bedroom closet by the end of next week?

I am sure that you have become aware how difficult it is to completely avoid the risks of picking up bed bugs and carrying them home. Bed bugs have natural enemies, but it is arguable that you would rather have bed bugs than the insects that prey on them – cockroaches, ants, spiders and centipedes – and insecticides are not always effective.

The one thing that certainly kills them, besides being trodden on by a size ten army boot, is heat. No stages of the bedbug’s life can withstand temperatures above 45c.

This may be noteworthy, because modern washing powders are intended to get clothes clean at 30c, thereby saving electricity, but they also unintentionally save the lives of the bedbugs on your clothing as well. You can make sure that your clothes are bedbug-free by washing them at 46-50c and you can kill existing bedbugs in your house by steam cleaning it, which is the professional way of exterminating an infestation of bedbugs.

It is time for people to be aware of this fairly new threat to their well-being. The key things you can do are: acquaint yourself with what a bedbug looks like and have your clothes laundered at temperatures above 46c if you think that you may have been exposed to an infestation of bed bugs.

Hotels Can Have Bed Bugs Too

The revival of the population of bed bugs over the last fifteen years has been attributed to the increased number of people going on long-haul holidays and the enlarged amount of immigration from Asia and Africa. It is not that people carry the bed bugs back on their bodies, but bedbugs may have laid eggs in the travellers’ clothing or the bedbugs may have taken refuge in the luggage.

In this manner they are transported home, and being very resilient to temperature change they thrive in their new home country. If the carriers are holiday makers, then the bedbugs could easily be brought into the hotel. This is how bed bugs can be distributed unknowingly by humans.

You see, bed bugs do not prosper in a dirty environment of necessity. Bed bugs do not mind whether you dropped a bit of potato on the floor last week and did not pick it up. They do not eat what we eat, even if they are starving. They only eat blood.

If you exist like this, then you will attract mice or rats, cockroaches and ants, but not bed bugs. It is a mistake to think that bedbugs like grime and filth. They most likely prefer it quite clean actually, but they do have to have cracks and crevices to hide in, but there are lots of those in most rooms.

They like to wriggle behind the skirtings and other woodwork. They also like damaged plaster, loose wall paper and ripped mattresses. Because they are so flat, they can get into almost any crack. This means that every hotel can be infested with bedbugs, the Ritz, the Carlton, Holiday Inn – any of them.

This is the problem for us. If it was only run-down, dirty hotels that had bed bugs, we could stay away from them, but you just cannot judge a book by its cover.

There are methods of checking your room though. Look out for small bugs that look a bit like an apple seed. Look in the seams of the chairs and check the mattress, if there are any rips in it, have it swapped.

You can also test by lying on the bed to warm it up and then throw back the bed clothes swiftly. You may spot a few fleet-footed insects running for cover. They are bedbugs.

Obviously, the first thing you have to do is warn the hotel manager. If you are not satisfied that he or she is taking you seriously, move or / and ring the environmental health department of the local authority.

Whether you find bedbugs or not, they still may be about to snag a ride home with you, so spray or dust your suitcase with a powerful insecticide before you fly home and to be really safe, have your clothes boil washed, because bedbugs cannot endure temperatures above 45c.

If you cannot arrange this on the last day of your holiday, make certain you do it when you arrive home, but make certain that you do not give anything you have brought with you a chance to escape and reproduce.

How To Get Rid Of Bed Bugs

It is doubtful that you grew up with bed bugs and the chances of you having come across one over the last fifteen years is still reasonably slender, but the chances are increasing. In some parts of the world’s inner cities, the incidence of bed bug encounters has risen by up to 100% per annum since the year 2000. Another report says that of 700 hotels surveyed, twenty-five percent of them had issues relating to bedbug infestation.

The key problem with bed bugs is their detection. Not everyone has a reaction to bed bug bites and if they do, it can take up to nine days to develop. That means that you could easily reprimand a hotel for the infestation, when you were bitten thousands of miles away on a different continent.

This can be a real problem if you travel a lot. Then there is the reality that bedbug bites are not easily perceptible. There is no red mark in the middle of the lump as with mosquito bites, but they are often in a line of three, just like flea bites.

The good news is that although bedbugs are capable of passing on human diseases, they never have done so far to date. However, it is a terrifying possibility, if it ever were to take place.

The bad news is that they are barely affected by normal domestic pesticides. This is because bed bugs have become almost impervious to the standard pesticides available off the shelf in your superstore. Bedbugs also have a waxy top coat, which prevents surfactant pesticides from being completely successful in destroying them.

Therefore, the most effective bedbug killers endeavor to scrape off this waxy top coat. Some bedbug sprays do this by including powered glass or powdered silica, which sticks itself to that waxy coat. As the insect squeezes itself into thin crevices, the powder rubs off the wax. This then permits the pesticides to do their work. The downside of this approach is that it will take several days to get rid of them.

Professional bedbug exterminators use steam to get rid of an infestation these days. This is because no stage of the bed bug’s life, egg, nymph or adult can survive temperatures above 45c. If you want to try getting rid of your bedbugs yourself, you could hire a wall paper steam stripper or buy a hot air paint stripper. These will produce a temperature sufficient to destroy bedbugs.

The locations where bedbugs like to go into hiding are behind loose skirtings and architraves, in cracks in plaster and behind tears in wall paper. Their number one favourite of all time though is inside a ripped or torn mattress. They like to be as near to their victims as they can, which is something to keep in mind, when you go looking for bed bugs’ hiding places.

The other method of solving your bed bug problem is to call in the experts. This is also the best, if the most expensive, method of doing it, but at least you will know that your bedbug problem is over and you should get a guarantee too.

What Are Bed Bugs?

If you wake up one morning with prickly lumps on your body, you will probably think that you had been bitten by mosquitoes or ants the night before, but there is also a possibility that bedbugs have got at you. If this occurs in your own bed, then you have problems. If you are in a hotel, go and make a complaint to the manager.

You can be certain that most hotel bosses will take complaints about bed bugs very gravely, because it is well known that the numbers of bedbugs are increasing fast and have been since 1995. It is also common knowledge that huge compensation awards have been made against hotels. Some of them were at hundreds of thousands of dollars.

Most so-called ‘bed bugs’ will only feed on humans if their favourite host, often chickens, are not available, but there is one that only feeds on human blood and that species is called Cimex lectularius.

Cimex lectularius was virtually extinct in the developed world by the late 1950’s because of the extensive use of DDT in residences and hotels to eradicate all insects such as ants, bed bugs, silverfish, millipedes and cockroaches.

However, there has been a gigantic revival in the number of bedbugs since 1995. In fact, between 1995 and 2001, one report on bedbugs in London stated that incidents of bedbug call-outs had doubled every year.

The resurgence in bedbug numbers has been ascribed to global travel and immigration from Asia and Africa. However, it is also likely that they were never completely eradicated and that they have become tolerant to modern pesticides. There is not much you can put down or spray around now that will kill bedbugs.

So, what do bedbugs look like? Well, there are lots of different types of bed bugs, but most of them are brownish, unless they have just fed and then there is a red tint to them. However, they can also be white to yellowish. Sometimes, they look banded because bedbugs are covered with short hairs which reflect light like a stripy lawn.

Bedbugs have a beak-like mouth-piece with two tubes. One tube squirts spittle into you and the other sucks blood out. The saliva contains anti-coagulant and a pain-killer, so that you do not know that you have been bitten until long after the bedbug has gone home.

Some people never know, because they are not allergic to the saliva, others get a bump or slight swelling almost immediately, but sometimes the swelling can take a week to come out. These bites may or may not be itchy.

If you travel a lot, or if you go to parts of the world that are less concerned with hygiene, you must be careful about not taking bedbugs home with you. They will not remain on your body, but they may lay eggs in your clothing or hide in your suitcase. Therefore, either before you go home or without delay on arrival have your clothes washed at a temperature above 46c and blast your suitcase with a jet of steam or hot air.

How Many Eggs Do Bed Bugs Lay?

Do you know whether you have ever come across a bed bug? You probably have not. Not yet, but the odds that you will are increasing every day. This is because bed bugs are undergoing an explosion in their numbers and mankind is quite helpless to stop them at the moment, although a lot of people are working on it.

You see, the problem is that bed bugs are pretty much tolerant to every insecticide that we have. They were almost wiped out in the West in the Forties and Fifties with the extensive use of DDT, but the ones that survived and the ones that have been brought into the country are resistant to pesticides.

Scientists are working on insecticides that will be effective against bed bugs, but there is no light at the end of the tunnel so far.

So, we are stuck with a burgeoning population of bed bugs. How do you get bed bugs? Usually, you just pick them up and take them home or someone does it for you. It is thought that foreign travel and immigration are largely responsible for the first members of our new bed bug community.

These days, you can pick them up anyplace where people go: taxis, movie theaters, bars, hotels, motels, cars, buses and planes. Even in the doctor’s surgery.

It used to be believed that bed bugs only flourished in poor peoples’ houses, but this is incorrect. In fact, the rich are more likely to get them than the poor, because they travel more often. You can also be given bedbugs in secondhand furniture, clothing and suitcases.

Bedbugs like to creep into in cracks, so you could be sitting on a bus and one will clamber up the back of your coat and nuzzle under your collar. There it might lay a few eggs and walk off or it might go to sleep. When you get home, you will put your coat in the wardrobe and a few days later you will have your very own family of hungry little bedbugs. It is that easy.

Some bedbugs will also live on birds and bats. These bedbugs would rather bird blood, but if there are not many around, you may find them dropping from the ceiling onto you, if you have birds or bats in your loft. Bats are protected now, so you will have to have them removed, but you ought to discourage birds from nesting above you.

The bedbugs will be attracted to the CO2 on your breath and your body heat and then they use pheromones to tell the others where you are. It usually only takes a bedbug five minutes to feed and then it goes back home to sleep it off for three to five days.

A mature bedbug has gone through six moultings and after a mature female has been inseminated, she can lay between 300 and 1,000 eggs in her lifetime of about six to twelve months. She will lay several eggs a day and they will hatch out in around ten days. So, you only need one pregnant female and you are in trouble very soon.

If you have a couple of dozen females laying eggs in your mattress, it will take less than a fortnight before dozens of baby bedbugs (called nymphs) are hatching out every day and then one of their relatives will lead them straight to you.

Tackling Garden Pests

If you have a lovely garden of flowers or / and vegetables, you can be sure that you will not be the sole one appreciating it.

However, the vast majority of the others will be unwelcome. Pests are bound to be eying up your plants with evil intentions as far as you are concerned.

If you prize your flowers and vegetables you will have to do something to cope with them. How earnestly you take this quest is naturally up to you, but a garden will soon get overrun if you do nothing at all.

There are basically two ways of dealing with garden insects: there are items that you can use, so-called mechanical methods and spray killers such as insecticide and fungicide. These two ways offer an infinite variation of combinations to deal with backyard bugs.

A good instance of a mechanical method of protection is the covered frame. A covered frame is a five sided box with no bottom. You stand it over your plants especially while they are young. The top of the box may be perspex, glass or fly screen.

The plastic, perspex or glass top is good for protecting the plant from frost as well as bugs, whereas the fly screen will let the elements in but protect the plant from insects and birds. They might be thought of as winter and summer protection respectively.

A cheaper manner of protecting young plants from perhaps cut-worm, is to cut the top and bottom off a drinks can and then cut the body into three rings. Place a ring around a plant and push it at least an inch into the ground, leaving an inch or two showing. Leave the cut edges ragged and rough to deter slugs, snails and cut-worms from scrambling over it.

If that is too much trouble, you could use plastic bottle rings or cardboard treated with oil – maybe WD40 – which will ward off pests too as the above and stop it getting ruined by rain. . If you would like to spray your fruit, you will need a spray-gun. You can either get one with a compressor or you could pump it up yourself. The latter are much cheaper, do a decent job and provide more exercise.

The chemicals used in these sprays is quite corrosive, so buy a spray tank that will resist this. Aluminium, stainless steel or brass are the best, but you should take advice depending on the chemicals used.

Cheaper models will rust away fairly quickly. Make certain you may buy extension rods for spraying into trees if necessary.

Slugs and snails are not keen on travelling over rough terrain, so you should save all your egg shells, crush them into a coarse grit and lay them in a ring around your plants.

The weather will break them down, but they contain nutrients that are good for the garden anyway.

If you have an ants nest exactly where you do not want one, wait until the spring or early summer and lay a piece of slate or tile on top of the entrance to the nest. Put an upturned flowerpot on top of this and cover the hole in the base of it.

After a few dry days, the ants will have brought a few hundred eggs up onto the slate. You can eat these – Thais say they are an aphrodisiac – or you may feed them to your fish. After a few weeks of this the ants will become discouraged and will move their nest elsewhere.

How To Kill Bed Bugs At Home

Bed bugs are a mounting source of aggravation, particularly in the developed Western world, because bed bugs were mostly cleared out there by the late 1950’s.

This means that most people under 50 years of age had probably never seen a bedbug until after 1995, when they made a big comeback. Their numbers are still rising fast, so lots of people are thinking about how to kill bed bugs.

This is due to two major reasons: their natural toughness and their tolerance to modern household chemical pesticides. Their natural hardiness is due to a waxy coating on their bodies which protects them from surfactant pesticides to a great extent.

Their tolerance to chemical insecticides is most likely due to the fact that they were almost exterminated in the West in the 1940’s and 1950’s by the extensive use of DDT.

The waxy coating on bedbugs blocks their rapid dehydration, which is why they are capable of lying dormant for up to five months waiting for a fitting host to come along. It is also the reason why a lot of contact pesticides are ineffective. Therefore, one of the tactics for killing bed bugs is removing that waxy coat .

People understood this 150 years ago, but they did not have the technology to truly take advantage of the information. People frequently used to lay down crushed dried leaves or sharp sand.

In the 19th century, lime, ash and diatomaceous earth were utilized to wear away the outer waxy coat. The latter was particularly effective and has seen an upsurge in usage during the last couple of years as an option to chemicals.

One method of killing bed bugs that will not work is catching them and crushing them, even if you did wrap sticky insect bands around the legs of your bed. Bed bugs cannot fly, but they could still get at you. They are not disinclined to walking up to the ceiling and dropping on to you.

If you would like to try chemical insecticides, then there are three fundamental sorts. The first sort tries to mimic the effects of diatomaceous earth.

It is a spray that contains pulverized glass or silica mixed with a contact insecticide. This does not sound a healthy environment for humans or pets either though. Breathing powdered glass or silica seems like bad news.

Contact insecticides have limited impact, partly due to the waxy coating, but also because to be effective they have to be robust and this makes them a repellent, which means that the bedbugs will just keep away from it if they can.

Insect growth regulators are effective at wiping out the young, which is great, but the adults can live for about a year, so that is not so good, unless you are considering a long world cruise.

Contractors normally use steam nowadays, because none of the bed bug’s life stages can survive temperatures over 45c, so you could try| this technique by hiring a steam wall paper stripper or a hot air paint stripper for the weekend and going over your walls and woodwork. In fact, if all your wall paper and paint is hanging off, you may as well combine the job with your next redecoration.

Owen Jones, the writer of this piece, writes on many subjects, but is currently concerned with how to test for bed bugs. If you want to know more, please go over to our website now at Pest Management at Home.

Natural Ways Of Killing Insect Pests

There are occasions when it just seems that there are more insects than ever before. Maybe it is the warmer winters and wetter summers helping them breed more easily, or possibly it is because fewer people are using insecticides in their gardens.

It is quite understandable that a great deal of people do not want to use chemicals on their gardens, but not using anything at all results in a boom in the insect population.

During the last fifty or so years, people have become more and more accustomed to using chemical pesticides to poison household and backyard insect pests because they are a quicker and certain killer. So what can you do if you would like to manage the quantity of backyard insect pests, but do not want to use chemicals?

Well, you would have to go back to using natural insect pest killers, although most households have forgotten what their great-grandparents used to use to eradicate insects.

The following is a list of some of the natural methods of killing insect pests. However, not all methods or plants will be available in all countries.

Stinging nettles: if you cut down a clump of stinging nettles and steep them in water for a week or more, chemicals will leach out of the nettles into the water. Strain the water off and spray it on your plants. It will kill or discourage a great deal of backyard insects. You could also use it as a plant food, but you will have to be careful how strong it is.

Rotenone: is a natural insecticidal. It is made from the roots of the derris plant. It kills by attacking the stomachs of insects. However, it is rather slow-acting and has to be reapplied often in order to obtain the maximum effect.

Washing Up Water: soapy water of any sort will kill aphids amongst other garden insect pests. This is a very simple control to administer. Simply strain your soapy water into a spray gun (like an empty window spray gun) and blast your aphids.

Corn flour: you can sprinkle this around plants or skirting boards to kill insects. If a tomato hornworm or a cockroach eats some, the corn flour will swell up in the insect’s stomach with the bodily fluids in there and the insect will eventually explode.

Pyrethrum: will paralyze an insect, but it will also wear off, so it is frequently mixed with a poison to kill the insect off. Otherwise, you can sweep them up.

A mixture of cow’s milk, flour and water can be employed as a natural insecticide, funnily enough. It is very efficient at killing the eggs of insects. It also destroys insects themselves by clogging their breathing holes. In other words, they asphyxiate.

Neem is a very common tree in India and has medicinal properties too as insecticidal applications. This natural insecticide repels insects by means of an active constituent that mimics an insect hormone. It makes it hard, if not impossible, to digest food and it blocks their cycle of reproduction. It works best of all on insects that primarily consume leaves.
