How do you keep cockraoche & rats away at home?

I used the special chalk, but not last long it's gone. I hear my mother has used the rat bomb today. The rats are afraid to get near the things around it. Cats are also good for the house guardian.

with roaches try boric acid but it can't be used around pets. u can also get roach gels they work well. as far as rats try glue traps but first check and see where they r coming in there may be a hole somewhere plug it up.... we had a mouse 2 years ago and found out the board under our kitchen sink wasn't put in properly so we fixed it and thank fully no more mice. I hate bugs and rodents!!!!

Thats a difficult question. To get ride of the rats you can always try to find a cat. But sometimes cats are afraid of rats... You probably have to find the source of problem. maybe is something that is near your house that make a perfect habitat for this creatures. If thats the case you may try to talk with the owner in order to resolve the problem. If that doesn't work you can try to find some specialized service. they usually take care of the problem for you!
