In recent years, residents of megacities have had to state an interesting fact - from the apartments were lost cockroaches. Insects, which could previously have been etched out of the home only by dichlorvos, and then for a short while, simply disappeared. Some individuals can still be found in some apartments or private houses, but this does not go to any comparison with the former invasions of the black-and-red horde.
At first glance, this event can only be rejoice. The cockroaches are gone - and, thank God! The need to develop strategic measures to eliminate them has disappeared, it is now possible to go out to the kitchen at night, without fear of stumbling upon uninvited guests, scurrying about in your cups or plates with food.
However, a person is arranged in such a way that a change in the habitual course of things makes him feel anxious and anxious. "Where did the cockroaches go?" - every second asks, feeling even a little deprived of the absence of these familiar "pets".
It should be noted that scientists partially share the common people's anxiety about the disappearance of the Prussians, putting forward several versions of where the cockroaches have disappeared.
Why did the cockroaches disappear: version one
The cockroaches left, because they had nothing to eat. No, the amount of food in our homes did not decrease at all, however, from the point of view of cockroaches, earlier access to it was more free. Remember that a few decades ago plastic bags were a rarity: oil, for example, was packed in paper, and bakery products were sold for nothing. Now even the smallest detail is packed in a thick layer of polyethylene, it's extremely difficult to get through it to cockroaches. And the appearance of garbage bags made for cockroaches the extraction of food in general an impossible task.
However, this hypothesis does not answer the question "Where did the cockroaches disappear?" They had to go somewhere in search of food. But an increased population of these insects in no place in our country was seen.
Why did the cockroaches disappear: version two
They were killed by the abundance of household chemicals used by us in everyday life. The version, it should be noted, is rather unlikely, given the survivability of these individuals. It should be recalled that the Prusaks belong to one of the most ancient creatures on Earth, who lived in the era of dinosaurs. But, unlike giant reptiles, these hymenopterans managed to survive the glacial period and the fall of the Tunguska meteorite. Moreover, scientists say cockroaches are able to survive even after a nuclear explosion.
Where the cockroaches left: version three. More plausible
Cockroaches depress radio frequency radiation. Today it is difficult to imagine a person who did not have a mobile phone at home, but more often several, a microwave oven, a computer with Wi-Fi. All together, this creates a powerful radio-frequency field that affects all living things within its radius of action. It is possible that the body of cockroaches was too sensitive to this kind of radiation and the colony of the Prussians simply perished.
Where the cockroaches went: the fourth version. Also eligible to exist
Abundance in our products of genetically modified
Why the cockroaches left: version five. Fatalistic
Some researchers argue that in the past centuries, cockroaches disappeared on the eve of some kind of cataclysms. So, it is mentioned that they completely disappeared before the Second World War, and in China - before a major earthquake. Does this mean that the cockroaches with their disappearance are trying to warn us about the danger?
