where do chipmunks live?
I didn't know where else to post this, so here goes. I have 2 adorable chipmunks in my garden. They sneak some birdseed, no harm. Tonight, as I moved my sprinkler in my perennial garden, I believe I saw a chipmunk running up the cement foundation of my house into a space between the foundation and my aluminum siding. I had to bend down, and when I did, I saw a gap in the corner where it looked like some of the concrete had been dug out. On the ground, there is a pile of what looks like brown dirt. This gap was not there before, as far as I remember. It's right near where my faucet for the outside hose is, so I am in that spot several times a week. I went back a few times, and whatever is in there was poking it's head out a bit. Couldn't get a good look at what it is, but it was brown and tiny. I know there is something there, because shortly after, my dog was going mad smelling the spot and running in circles and whining. If he gets the chipmunk, he will kill it, he had a vole tonight and almost dispatched that before it got away. I don't want to kill the chipmunk but what should I do? I also don't want to fill the spot in with expanding insulation or steel wool to block the chipmunk inside the area. On top of this is an outside mud porch. I also have a basement and the foundation is the sidewall of the basement. I certainly don't want anything making its' way into my basement and dying down there.
I thought chipmunks lived in rock walls and wood piles. Suggestions/ideas?
