On the way to the Red Book: where do cockroaches go from the apartments of large cities? 10 probable reasons why these insects disappeared

Long-time and not very pleasant companions of man in everyday life - red cockroaches - are now practically absent in apartments.

The great result of baleen from big cities is confirmed by the dry statistics of the sanitary services: less than 10% of applicants are asked to save them from cockroaches, and the overwhelming majority, over 70%, want to bring out bedbugs.

On the one hand, the self-destruction of rows of six-legged Prusaks, peddlers of infections and allergens is a joyful phenomenon. However, it is alarming its suddenness. So let's try to figure out where the cockroaches are from the apartments?

What caused ancient insects to disappear so quickly, which arose 350 million years ago, survived, in contrast to dinosaurs, all natural disasters, especially resistant to chemicals and traps, perfectly adapted to warm human habitation, where food will always be found?

An exhaustive answer has not been found yet. There are, however, a number of assumptions.

Human factor

Ultra efficient insect control products. Perhaps the creators of insecticides have finally found a specific weak spot in cockroach biochemistry. The first candidates for the role of such a super weapon - "slow" poisons fipronil and hydromethylnon, which the poisoned individual brings to the nest on itself.

After a certain time, a lethal dose of the toxin accumulates in the insect community and it dies out completely. However, it remains unclear why the red-headed cockroaches disappear where they have never been treated with these poisons.

Electromagnetic waves.

Indeed, the urban environment is supersaturated with a variety of electromagnetic radiation: at standard frequencies of GSM mobile communications and GPRS in the region of 900 and 1800 MHz, in the range of television channels from 50 to 230 MHz, at the frequency of microwave ovens 2450 MHz, in the computer interval 20Hz-1000 MHz.

It would seem a very suitable explanation of where cockroaches go. There were even coincidences in time and place, when, after installing, for example, the masts of mobile communication repeaters, insects disappeared from surrounding houses.

However none laboratory test not confirmedthat electromagnetic radiation somehow harm the cockroaches.

GMOs and preservatives in food. Prusaks for centuries ate crumbs from the human table - and in this menu, unfortunately, potentially dangerous, but widely used substances appeared. The list is headed by: modified starch, pyrophosphates (preservatives and leavening agents), modified soybeans.

These laboratory tests are ambiguous. There is evidence that pyrophosphates can reduce the ability to reproduction, and the consumption of GMO products can change inherited traits. Nevertheless, for the mass one-time death of perfectly adapted insects of such causes is clearly not enough.

Radiation or chemical background of cities. Maybe this is the real reason why cockroaches disappeared in apartments? The environmental situation in large industrial centers is far from ideal. At the same time, it is difficult to imagine such environmental pollution in which people could live, and baleen neighbors would not.

The endurance of insects to chemical and radiation effects is much higher than that of mammals. Red-headed baleen six-legged, in particular, are excellent candidates for the settlement of the planet after a nuclear war.

REFERENCE! Why cockroaches survive after a nuclear bomb? The lethal dose of radiation for them is 20 times higher than the human one.

Infrasound and acoustic effects. Proponents of this theory see the reason for the disappearance in low-frequency oscillations that accompany technological processes at industrial enterprises and even in the bell-ringing of many built and restored churches.

Infrasound, of course, unpleasant for many sentient beings, and the alarm for a long time was a means against evil spirits.

It is not clear why the red-haired cockroaches are selectively affected.

Synthetic materials in everyday life. Popular and massive eurorepair - this is, most often, plastic coatings and linings, wallpaper of synthetic composition, linoleum and carpet with chemical impregnation. Such a "tasteless" filling of the rooms could well have come to dislike insects - but they also disappeared in those apartments where they did not do the repairs.

Sanitation. In fact, the elimination of the garbage chutes, hermetic and durable plastic packaging for food, plastic bags for storing food waste seriously cut the nutritive base with a cockroach. In addition, domestic food stocks has become much less.

At the same time, it’s not so easy to starve cockroaches - they can do without food for 40 days and digest, thanks to the intestinal bacterial microflora, completely inedible paper.

Causes of a biological nature

Perhaps it is biological factors that are to blame for why cockroaches from apartments disappeared?

There is an assumption that the red cockroach could not compete with pharaoh ants, who willingly lodge in the warm and nourishing housing of a person. After all, exactly the same in their time, the red-haired Prusaks survived black cockroaches in a harsh biological war of insects.

However, no one has yet observed the simultaneous existence of cockroaches and ants in a room or the settlement of ants in cockroaches. Red cockroaches always disappear first and only then, after a noticeable time, the yellow pharaoh ants can occupy the vacant ecological niche.

Global change

The reasons for the mass extinction of cockroaches are also called:

  • The destruction of the ozone layer, climate change, the shift of the magnetic poles. As a result, leading biorhythms of cockroaches get off. It is not clear, then, why this same fate does not comprehend the entire terrestrial biosphere.
  • The supernatural scent of these insects on future cataclysms and disasters: economic crisis, major wars, large-scale disasters. At the same time, the "great outcome" of cockroaches is already 8-10 years old, and the end of the world has not come.

Apparently, none of these theories alone explain the apparent lack of cockroaches in large cities. Perhaps several factors act together, or perhaps these geniuses of adaptation, survival and endurance have not disappeared anywhere.

What if red cockroaches simply migrated to more suitable places for themselves? Maybe you should ask not why, but where did the cockroaches disappear from the apartments? Basements, manholes, old high-rise buildings, dormitories and prisons?

Silent and leisurely, generation after generation, they mutate, adapt and one day, strong, hardened and resistant, will return as massively as they left. Are citizens happy?

Interesting Facts! Did you know that there are more than 5,000 species of cockroaches? There are green individuals and even flying ones, but there are no white albinos. These insects can get into the ear or nose and even bite a person.

If you do not feel that the Prussians have left you, then we will give a list of effective drugs against them:

  • powders: FAS and Clean House;
  • crayons: Masha;
  • gels: Dohloks, Global, Forsyth;
  • aerosols: Combat, Raid and Raptor.
