I was mowing our front yard last year and when I got to this certain spot, I mowed and too late, this little thing popped up out of the ground, and I ran over it. There was no way anyone could have seen this. I did not know that they burrowed into the ground, I got down on the ground and looked and it was like a cone shaped nest and all of these little babies were just crammed in there. After that devastating episode, I put a few garden sticks around where the nest was. I sure don't want to do that again.
