I’ll have to check into those. We have more chipmunks than anything. My next door neighbor keeps a tally of how many he gets rid of every month. It’s impressive.
We just stick a cube into one of their many holes. They have two families a year. They did a lot of damage to an elevated stone patio we had. Inside was settled sand, they had a whole structure of condos. Had to put metal sheeting in between the sand and the bricks so they could not get in there.
