Cockroaches in the apartment? These are nimble, 12-15 mm in size, and they can transmit dangerous diseases that is also quite a number. Especially where it is nice and warm and with high humidity, as is usually the case in the bathroom or in the kitchen, they feel very comfortable and an infestation has nothing to do with filth or rubbish lying around.
A cockroach carries its eggs in it and it must therefore be trodden under any circumstances, since they would otherwise be distributed freely. It is no matter what poison you use ultimately, it is extremely important to carefully read the product and use information, and to note!
All cockroach killers should be kept away from food or feed!
Of course, the toxins must be kept away from children and pets!
Cockroaches are very durable and they would even survive a nuclear war. For this reason, you can contact for help to a specialist. Do you want it in advance but rather try yourself; you can wherever the animals were sighted, sticky traps attached. You can find it now in every supermarket and the cockroaches stay on their exploring stick to it and can then be disposed of together with the case.
Somewhat more effective it is when you use borax powder. Roaches do this powder very much, and when they have eaten, they die after a short time.
Of course, there are commercially still a whole lot more of special cockroach poisons in the form of gel, sprays, powders or tablets, which are all more or less effective. But no matter what you used to fight, to do a thorough check after a few days do not you come help, because it often happens that the crawler store shortly before her death, nor their eggs and then suddenly the next crawls Generation well in the next apartment.
