I guess that's one of the downsides of Florida. We have armadillos digging up the yard, and they've dug a nice tunnel under the slab of my air conditioner units. I don't want that damned thing cracking. I've thought about shooting them, but my neighbors are close and probably would have an issue with me discharging firearms at midnight. Someone also mentioned mothballs, though that seems like urban myth rather than science. Anyone ever been successful?
