Hi! Some neighbors and ourselves have found that a big part of our neighborhood has a large mole problem. We have treated for grubs for 3 years and it has not slowed the problem down at all. What is the best way to deal with this mole infestation for our whole neighborhood? We mostly live in the Rockledge area of Bowie, MD. Thank you!
Research has proven that grub control does not control moles. They simply eat something else in the soil, such as worms. You cannot control them by eliminating their food source.
Moles aerate your soil and eat pest insects in the soil, so in that respect they are beneficial. They do not eat roots, bulbs or damage plants. (Voles do.) Usually they inhabit a particular area for a while and move on. (They are loners. One mole makes a lot of tunnels because when foraging for food they only use the tunnel once. It can look like a lot of moles, but only be one.)
Mowing usually tamps down tunnels and we generally advise you ignore them because they are temporary. Foxes, hawks and other predators reduce their numbers. Trapping is the only proven way to get rid of them. Here's how to go about it: https://extension.umd.edu/hgic/topics/moles
