Your Local Exterminators
There is, of course, reasons for each, if you have cats then a chemical free method can be ideal because the bait will kill your rat and not your cat. If you are one of those few people with a pet mouse then a trap could be ideal, because you catch the rat without killing it.
However, if you are like the vast majority of Americans, you will probably like to get rid of your rat infestation by hiring a professional. If you live in the greater Atlanta area then this Dunwoody, GA Pest Control Company will take care of all your needs.
