Barefoot, we're talking about LAWN pest control being applied indiscriminately. Pest control being sprayed around the perimeter of the house is different. But I don't think even that needs to be done on a monthly basis. In the 7 years we have lived here I'm lucky if I remember to spray once or twice a year and we don't have a bug problem. We get those real tiny ants around the dry cat food dishes once in awhile so I'll put some traps out. The few bugs that have gotten in are soon discovered by the cats. And when we first moved in we had some red ants but I put Amdro on those and haven't had any more. Maybe there are more bug problems in the older areas that have more mature trees.
