In addition, take preventive measures to make your home less attractive. Change traps and reapply insecticide on a regular basis to combat cockroaches as they hatch. Lay down insecticide or roach traps under the sink, behind the toilet, alongside the fridge, or in other places where they may lurk. Once they’ve moved in, getting rid of cockroaches can be difficult, so take strong, swift, and sustained action, which may include consulting one of the best pest control companies ( Orkin and Terminix are top options). If you see one-usually in the kitchen or bathroom-you can be sure there are many more that you don’t see. Cockroaches are a problem all over the country, but especially in big cities.
