Getting rid of trees planted by squirrels

Question

I have several trees that have been planted by squirrels. A couple of them have gotten trunks that are about 2 inches in diameter and are coming up between concrete. I have been cutting them down and putting weed killer on them, but it does not seem to work. Can I drill holes in it and pour something in the holes to kill them for good?
