Where did the cockroaches why they disappeared and where to go?

"Why leave cockroaches and where?" - more often asks people. For centuries, we lived near indestructible parasites and have become accustomed to the invasion of insects at home. So why cockroaches disappeared, occupied our kitchens and bathrooms since time immemorial? Scientists and journalists have sought to ascertain the reasons for the disappearance of cockroaches, pushing the most incredible version.

In recent years, residents of cities had to ascertain interesting fact - from apartments cockroaches disappeared. Insects, which previously could only erase from home dichlorvos, and then not for long, just disappeared. Some specimens can still be found in some apartments or private homes, but it does not go to any comparison with the past invasions black and red hordes.

At first glance, this event can only rejoice. Cockroaches have disappeared - and, thank God! There is no need to develop strategic measures for their etching, the kitchen is now at night you can go without fear of not stumble upon a petition of guests, you scurrying into cups or bowls with food.

However, a person is designed so that a change in the usual course of things gives him the feeling of anxiety and worry. "Where did the cockroaches?" - asks every second, even feeling a bit deprived of the usual lack of "pets."

It should be noted that scientists are partially shared by inhabitants of alarm over the disappearance of the Prussians, advancing several versions of where the cockroaches disappeared.

Why cockroaches disappeared: the first version of the

Cockroaches are gone, as they was nothing there. No, the amount of food in our homes is not decreased, however, from the point of view of cockroaches, before access to it was more free. Recall that a few decades ago, plastic bags were a rarity: oil, for example, are packed in paper and baked goods sold at all for a reason. Now, even the most insignificant detail is packed into a thick layer of polyethylene, which is to get through the very difficult cockroaches. And the appearance of garbage bags made for the production of food cockroaches at all a daunting task.

However, this hypothesis does not answer the question "Where did the cockroaches?", Because they are in search of food had to go somewhere. But the growing populations of these insects in any place of our country has not been noticed.

But, unlike the giant reptiles, these Hymenoptera successfully survive the ice age and the fall of the Tunguska meteorite. Moreover, the scientists say, cockroaches can survive even after a nuclear explosion.

Where did the cockroaches: the third version. More plausible

Cockroaches inhibits radiofrequency radiation. Today it is difficult to imagine a person who was not at home to a mobile phone, and more - a few, microwave, computer with Wi-Fi. All together it creates a powerful radio frequency field, which affects all living within a radius of action. It is possible that the body of cockroaches was too sensitive to this kind of radiation and the colony Prussians simply destroyed.

Where are cockroaches: the fourth version. Also has the right to exist

The abundance in our products of genetically modified organisms depressing effect on their reproductive function. In a word, it happened to them is what scientists have long warned - because of malnutrition these insects have lost the ability to reproduce. If this hypothesis is confirmed, then mankind should seriously ponder over their own future, because one day we can be on-site accidents cockroaches.

Why cockroaches are gone: the fifth version. Fatalistic

Some researchers argue that the cockroaches disappeared in the past century in anticipation of some disasters. So, it is mentioned that they have completely disappeared before World War II, and in China - before the big earthquake.
