Used to have one at a time around house. Would trap it and be chipmunk free for a few days. Last couple years I can not keep up. Not unusual to see several at same time at various spots around house/yard/property perimeter. Biggest damage is caused by my 2 Pit Bulls trying to catch or dig out the chipmunks. One spot where cement drive meets garage & sidewalk is a few square feet of bare soil my wife usually plants annual flowers every year. Last week she has officially given up. Chipmunks have a hole under the cement and the dogs have destroyed countless flowers either dug out or broken off. Replanted 3 times in 4 days last week. I told her to give up, plant a small bush/ shrub, or use hard scape. She finally agreed.
Not trying to make any points here!! I just bought a new toy (RAR 17hmr) and since I don't live on the farm anymore I was hoping to find someone who was pestered and overrun with them. You cant hunt them on the FWAs Just thought I could help someone out and get some trigger time for me.I doubt that anyone understands what you are trying to find out and why, or the point you are trying to make.
