OK - so we have been battling some creature in our front yard. It is in the area we have landscaped between our front porch and sidewalk to the front door. It started out smaller, but seemed to get bigger with time. At first I thought snake hole - but then the size increased over time.
Dh has flooded it with a hose, packed it in with dirt, etc... (did this a few times).
The hole returns after a few days every time. This time he went and bought some kind of pesticide.
We suspect mole - but have no clue. We had a mole years ago - but there is not "out" hole that we can find - only one entry/exit hole.
2 years ago we saw a coral snake in our backyard, so I am now skittish about the snake situation.
Either way - the hole wound up way too big to be a snake, I THINK...
