Cockroaches walk in strips on foot, they feel great. In a week I saw only one who was booming, everyone else was alive. What price, such and quality!

I saw one cockroach in the apartment, decided Mashenka to kill him. Outlined almost the entire kitchen, bath. A week later, there were already 10 of them crawling, went for an aerosol.
