The extermination of rats is usually done by three methods: biological, chemical and mechanical. The most common and effective among them is chemical. Sanitary-epidemiological station (SES) conducts it successfully, with cereals, poisoned. But there is a problem: a long smell of the deceased out of reach of the rodent. And in a private house or in the country not to avoid. If neither the dog nor the cat can’t protect you from the rat visits (and maybe no way to keep these friends of the person) – then try a mechanical method of destruction, having made the proposed rat trap.
Bait placed on the hook in the trap. (Distance from floor to the hook – not more than 20 mm). Each trapped rodent dies down and only in the morning when your approach begins to rush.
