I finally stopped spraying my crawlspace every month and the roaches in my Decatur house got worse before they got way better | Atlanta Pest Control - Vivisector
Used to think spraying every month was just what you had to do down here, like it was keeping things from getting out of hand. Turns out the spray was killing off the spiders and centipedes that actually eat roaches, so once I quit, the roaches party hard for a few weeks then the good bugs move back in and handle it. Wild how that works but it did for me too.
