First it was raccoons with the isolated possum and/or groundhog/neighbor's cat which we trapped endlessly for several years in Collinsville. We have the opinion we may have ended the raccoon run, but now we've a couple of groundhogs making themselves home in our yard.
I saw one walking down the driveway last week and when he saw me he ducked under our next door neighbors' deck. But today while working in the yard I came across two freshly dug deep/big holes which can only mean...groundhogs.
You can see the hole and all the kicked back dirt.
This hole had a high mound of dirt behind it.
