If you said 4 you are incorrect. It's 200 hundred roaches in one draw that are going to be infesting this kitchen. This is just 1 draw. How many draws does your kitchen have? This will ruin all the cleaning and disinfecting you did to get rid of the cockroachs and re-start it all over again. Sanitation is the key to eliminating your cockroachs as well as a good pest control program. A roach program needs follow after a treatment especially after a heavy infestation.
