"Much folklore exists on how to get rid of moles. But there is little evidence that flooding; putting chewing gum, castor oil or dog hair in the holes; firebombing; or ultrasonic pest repellents actually work. Be careful not to create a larger problem for your yard than the moles present. After all, moles will aerate your soil, add organic matter to your garden and kill unwanted and harmful grubs before moving on."

I say leave the poor little fella be.
