Moles will be attracted to your yard because of the number of insects in your soil and the ease of digging through it. Most species enjoy wide, open spaces to do this. If your yard is large and unobstructed, your mole damage may be particularly extensive. Since they move about underground and usually only come on land to find a mate, you may not ever see a mole itself. Their tunnels, however, are clear signs that this pest has invaded your property. Even though they can reach as deep as a foot, moles tend to kick up dirt overhead that causes large mounds running the length of the tunnels, crisscrossing throughout your yard.
Moles have been known to transmit rabies, although their biggest danger is parasites like fleas and ticks. It is best to keep your distance if you see one, especially if it seems aggressive. If moles are currently a pest issue, limit your pets’ time in your yard and carefully inspect them – as well as yourself – after being outside.
