I don't blame you for the in the house rule. I have lots of green snakes outside but when one got in the basement it died within seconds of attracting my attention. The ants are a big problem. I think you can get a pesticide that you spread like fertilizer all over the lawn with a lawn spreader.
Mole , vole , etc I have no idea. We had a few moles onle year but they disappeared and never came back. Chipmunks are cute...leave em alone!
