Two years ago construction for a Whole Foods was started down the hill from my house. The neighborhood filled up with rats escaping the construction. I had to bait my crawl space and yard with comercial duty green bait. 50 dead rats, 2 raccoons, 1 opposum, sent the neighbors dogs to the vet for a stomac pump of dead rats. No more rats....all dogs smarter now...
Funny how the neigborhood cats knew not to eat the dieing rats but the dogs didnt......
You have to act swiftly and with prejudice with rat invasions or their first litters will overwhelm your property and your home. Some of my neighbors still have rats in thier crawl spaces.....mine only has DECON.
