Why are bedbugs infested in an apartment or house

Blood-sucking insects, which are trying to penetrate into urban apartments, are a real disaster today in many developed countries. If earlier it was thought that bed bugs and fleas - this is the lot of nerey and marginal, but now these parasites are found in the homes of quite respectable citizens. What makes the bugs in the apartment - the most common versions of their appearance.

Historical and statistical data

In Europe, bedbugs appeared only in the XI century. For the first time they are reported in German historical documents of the time. Archaeologists claim that these blood-sucking parasites got to humans from bats, with which primitive people shared dry caves. In the fossils formed from organic sediments 130 million years ago, ancestors of bed bugs are found, parasitizing on dinosaurs. A large amount of biogenic iron around insects indicates the source of their food - blood.

Migrating from the advancing glaciers, a man in his belongings carried bugs across all continents, but most of all he liked the warm climate. In Asia, and now lives the largest population of blood-sucking insects. Together with travelers, caravans of merchants insects spread farther. In the thirteenth century they settled in the houses of France, in the XVII they reached England.To the east the bugs got only in the XIX century.

With the beginning of the mass use of insecticides in the XX century, it was believed that with blood-sucking insects will be completely over. And while the underdeveloped countries "itched" from lice, fleas and bedbugs, economically prosperous bleed bloodsuckersusing increasingly sophisticated tools.

Domestic bugs by the end of the last century began to give up their positions. But then the “iron curtain” fell, people began to travel the world and bring “exotic gifts” in their luggage to their apartments and houses. One of the bloggers, traveling the world, describes his unexpected meeting with bedbugs at a five-star hotel in Barcelona (Spain) last year.

Scientists report disappointing research results. Over the past 15 years, the number of blood-sicking synanthropic parasites in economically developed countries has increased several hundred times. Over the past two years in New York there has been an increase in their number by 500 times. More than half of the apartments were infected. Let us consider in detail the scientific and near-scientific versions, from which the bugs start up in the house.

Bug Population Versions

The first is geographic

Bedbugs and travel

An increasing number of tourists visit exotic countries in which bedbugs themselves feel very well. People in their luggage deliver live imagos and their eggs to their homeland. Passion for visiting the countries of the Middle East, China, Vietnam, Central Asia increased the risk of infection. Collecting collections of antiques and souvenirs, people bring “emigrants” to their apartments, and in fact it’s worth getting into favorable conditions to just one female and considering breeding characteristics of bedbugsAfter a short period of time, hundreds of her “children” will fill the house.

But even a visit to the developed countries does not mean that the traveler will not find “settlers” in his apartment. In Florida, seven years ago, they bred in large areas, increasing their number 10 times. In Switzerland - by 70% compared with the end of the XX century. In Zurich, half of the apartments are inhabited by "bloodsuckers." There is a global trend of increasing the number of bedbugs.

The second is economic

An economic downturn always entails an increase in the number of parasites. With the emergence and increased popularity of Second Hand stores, scientists have associated a new wave of synanthropic ectoparasites.An adult can do without food for about a year, so long journeys in the holds of ships, on board an aircraft or wagons of cars do not frighten bloodsuckers. Getting into the country with unwashed, second-hand clothing in our country, “illegals” settle in new territories. If bugs are wound up, look more closely at new acquisitions — folds of clothes, household appliances, computers, furniture.

Often there are messages in which people complain that bedbugs started up at home after new furniture was brought to the apartment. So not only old things can serve as a source of "immigrants", but also new clothes are rewarded with unintentional joy. Bedbugs in the couch or a new chair can get from the store, if the neighboring houses are infected with them, or from the clothes and shoes of buyers looking after furniture.

In boutiques for clothes bedbug eggs can get during fitting. “Street bugs”, expanding their “hunting grounds”, penetrate through the ventilation shafts into other apartments and houses, feeling the smell of pheromones, with the help of which their relatives mark “the hunting path”.

Third - climatic

The Commission on the world monitoring of the number of bed bugs voiced another version of why bed bugs are infused. According to scientists, their size and widespread influence of climate change on Earth and the emergence of a larger number of heated premises. These factors have led to the fact that in favorable temperature conditions the rate of reproduction and the fecundity of bugs increased significantly. The period for which larva becomes a mature individual, ready for procreation.

The fourth is political

Another version of scientists - where the bugs are getting from, echoes the first and second. The recent economic recession in the world is leading to migration and the displacement of labor, especially from economically underdeveloped countries. Coming to work, people live crowded, in conditions far from normal. Often they populate old, long-abandoned houses, which are full of all the "living creatures."

Bugs in the house

With the flow of refugees and "illegal immigrants" now no country can cope. Illegal "hostels" are not checked by health services,which is why a wave of synanthropic parasites literally swept homes in wealthy and “clean” states and remove bedbugs getting harder.

Fifth - housing

Economic difficulties have also affected services that should monitor the state of the housing stock. In the basements affected by mold caused by dampness, ectoparasites reproduce, which rise to warm apartments, closer to the power source.

Blood suckers do not drink water, but they need moisture to maintain fluid balance in the body. Therefore, they prefer to settle in houses where it is warm and humid. In a dry atmosphere, insects quickly lose moisture and die from dehydration. Particularly sensitive to the humidity of the larvae.

In the basements of the house, homeless people huddle, they spend the night on the stairwells, bringing with them colonies of lice and bedbugs. Multiply in unsanitary conditions, the parasites crawl into apartments. Therefore, it cannot be said that bedbugs do not start up from dirt, it’s just that dirt can be outside the apartment.

Sixth - biological

On the shelves of stores exposed a huge variety of means of combating parasites, but for many of them the bugs have long been adapted.Due to the fact that arthropods multiply very quickly and can pass on insecticide resistance by inheritance, whole populations of “bloodsuckers” have appeared, which are difficult to exterminate with conventional chemicals.

These are the versions that explain in detail and scientifically how the bugs are infested, shared the participants of the annual entomological conference in Annapolis (USA, Maryland).

The world continues to conduct research to create the most effective means of bedbugs in the house. What to do if blood sucking parasites start? This question was answered in the journal Angewandte Chemie by Canadian entomologists. For eight years, they created a universal remedy for bed bugs. Using the synthetic pheromones with which these insects lure a member of the opposite sex, they made a trap capable of collecting all the "tenants" in a house within a radius of several tens of meters.

Inside the trap there are "holding" substances and histamine is an organic substance that is a regulator of instantaneous allergic reactions. Getting on the insect, it causes inflammation and death of the "vampire".Imago and larvae that have not died can simply be drowned. Catching a bed bug and then destroying it in any convenient way is the goal of the invention of scientists from Simon Fraser University.

After a detailed explanation of scientists, how bedbugs are infested, consider how to get rid of parasites at home.

How to deal with bedbugs

Until the traps from Canada have entered our stores, fight bedbugs already tested methods.

If you find a bug in an apartment or house, then somewhere there is a whole colony of "bloodsuckers." In bed, they are just to eat. Most of the time insects lurk in the crevices of the floor, behind baseboards, household appliances, under bed mounts and furniture. The bugs are hiding on the walls of the house under the wallpaper and in the sockets, so they are difficult to detect.

The fight should be conducted systematically:

1. If excrement and blood specks are found in the bed, in the morning the body is covered with characteristic paths from bedbugs bitesthen you should carefully examine all the rooms in the apartment and clothing.

2. Remove and clean carpets and curtains, vacuum upholstered furniture. Move furniture away from the walls of the house and wash the floor with an insecticide solution,plinth and back side of the furniture.
3. Wash clothes and textiles in hot water, dry in the sun and iron. Insects die at temperature. above 50 ° C and during severe frosts.
4. Furniture and floors can be cleaned. using household steam cleaner.

Bedbugs can not be crushed to not leave blood stains on light-colored fabric or wallpaper. Especially if there are red bugs. This color gives them not yet digested fresh blood. When eating, a “vampire” drinks up to 7 mg of blood overnight, mechanical destruction will not solve the problem, but may spoil the fabric or upholstery of the walls. On the abdomen of parasites are glands that synthesize volatile substances, warning the "neighbor" about the danger. The bugs, having received such a message, will hide in inaccessible places at home, and it will be impossible to “smoke” out of them.

After the main preparation of the room for processing will be completed, you can proceed to the chemical destruction of parasites. Anyone can do this. effective household remedy for bedbugssold in the store. It should be sprayed in places likely to dislocate the colony, thoroughly moistening the surface.

It is necessary to know how bugs get divorced, because many means of fighting with bloodsuckers destroy only adults and larvae, without acting on laying eggs. Therefore, after a time, it is necessary to re-process in order to destroy the young hatched insects.

In the room where small children sleep better to use folk remedies for bedbugs:

• for this fit vinegar solution, essential oils orange, clove, pine, etc.
• to create barrier protection to penetrate into the apartment of the “neighbors” bloodsuckers, you need to use an insecticidal pencil - the border outlined by this tool around the door and window frames, bugs will not be able to overcome.
• in the ventilation shafts, air ducts, cabinets with clothes should hang sections repellents.

V. Mayakovsky, L. Tolstoy, Yu. Entin, and others wrote about bedbugs. In his story “Bugs,” Leo Tolstoy tells how he tried to protect himself from bed bugs in a hotel room. Putting the legs of the bed in a bowl of water, he carefully watched as the insects tried to reach him and sank. But soon the bugs began to bite the writer. It turned out that they fell into bed falling from the ceiling.

Those who are bitten by bugs know how painful the effects of bites can be. To protect yourself from an infection that can penetrate through the wounds and scratches, you must treat them with a disinfectant, bedbug bite ointment.

The fight against synanthropic blood-sucking insects has been waged by man since ancient times and with varying success. In order to create an effective means of dealing with them, scientists are studying the DNA of parasites. Perhaps declassifying the genome of insects, it will be possible to influence the reproduction system, “sterilize” the bloodsuckers and do away with them forever in city apartments and houses.
