Lifetime, life cycle

What do they eat and what are they harmful, do they bite?
Attracts cockroaches free living conditions and excess food:
- dampness;
- filled trash can;
- dirty dishes;
- crumbs on the table floor;
- not packaged products.
Mouth apparatus of black cockroaches allows them eat solid food. The intestine, where special bacteria live in symbiosis with insects, digests almost everything. It feeds on garbage, food waste. With a lack of recent eats paper, cloth, soap, wiring and their relatives.
Cockroaches not only spoil the products and things. They suffer infections:
- typhoid fever;

Big black cockroaches in the apartment, how to get rid of?
Temperature is below minus ten for cockroaches disastrous. In an unheated room in winter, they die. But this method of struggle, of course, is suitable only for exterminating them in summer cottages in the offseason.
Since ancient times in our country with cockroaches fighting folk remedies: laid out in their habitats orange peel, bay leaves, elder flowers, feverfew, boric acidmixed with boiled yolk of eggs. The sharp smell of these plants and substances, in theory, should frighten cockroaches.
In practice, these traditional methods are weakly effective. Cockroaches are one of the most ancient animals on the planet, they successfully survived dinosaurs. Evolution is made before our eyes: our ancestors successfully used these tools, and today we can see how insects crawl on them.
Killing cockroaches with slippers is a fascinating occupation, but you cannot destroy so many of them. You finish the whole pack, and the cocoons, meanwhile, lie in a secluded place. Soon, a new generation will emerge from them.
Somewhat more successful application of poisonous aerosols against cockroaches. Spray in the places of their food spray, you can sweep up the corpses of insects with shovels.
The disadvantages of this solution are obvious: chemical poisons are harmful not only for insects, but also for humans. Before the chemical treatment of the room it is necessary to tightly close the doors, windows, leave it for a while. Insecticide children can get poisoned.
Among other means of struggle, we mention traps with adhesives, labyrinths, electrodes; dusts, crayons, whose fumes paralyze an insect passing through a line drawn on the floor.
IMPORTANT! The most effective remedy today is special gels. From plastic syringes, they are squeezed out onto paper or coasters in places of mass pilgrimage for cockroaches.
For insects, the smell and taste of the gel is attractive, they eat it with pleasure. Then the masses die from poisoning.
Among such tools are the popular brands "Dohloks", "FAS", "Combat", "Sturm", Global, Clean House, Raptor. Unlike aerosols for humans, such means are safe.
If cockroaches live in an apartment for many years, and nothing takes them, experts can bring them out. Professional health services for a few hundred rubles will carry out a comprehensive treatment of premises harmless to humans substances. In the future, if you keep the house clean, the problem will be fixed for years.
The threat will remain, if the neighbors do not do the same, their breeding centers will remain in the sewer and garbage disposal, dampness will remain in the house. Conducting pest control in separate apartments, tenants stimulate the migration of black parasites to their neighbors. From there they can always return to you.
To eliminate this danger, one must agree on sanitation throughout the house. Particular attention should be paid to the elimination of sources of high humidity: eliminate leakage of hot and cold water in the basement, entering the staircase, through the roof, windows, cracks of atmospheric moisture. It is necessary to achieve from the public utilities timely and accurate garbage collection.
Wash dishes immediately, do not accumulate in the sink. After dinner, immediately sweep the crumbs off the table. Store bread, cereals in airtight bags, other products - in the refrigerator. Take out the garbage every day, it is better several times a day, especially if the garbage disposal on the floor. You can not accumulate it in a bucket.
Understand the causes of high humidity in the restroom, in the kitchen, in the bathroom. Find water leaks and fix them.
Dampness can also be the result of condensation of vapors in the kitchen. Air more often.
In a clean house cockroaches will not start. Their dwelling in the apartment eloquently testifies to the lifestyle of its owners. Change your habits, harmful insects will leave you alone.
