Moles dig tunnels underground, pushing the dirt or lawn up to form lateral mounds. These mounds not only affect the quality and appearance of your landscape, but also are dangerous, making the ground less level and unstable. Moles typically feed on earthworms, which is why you often see evidence of mole activity after a rain. There are many control measures, including home remedies such as using castor oil, but according to Ohio State University, trapping moles is the most effective mole control measure.
Locate where the moles travel most frequently. Along a fence, foundation or other borders are common paths for moles. After pushing down the soil on mole paths, notice if the earth pops back out within 24 to 48 hours. If so, this is an active path.
Look for hole openings that connect the active paths. Notice if after you fill the tunnels in with dirt, if they reopen within 24 to 48 hours. If they do, these are the main exits and entrances for the moles where you should set the traps.
Plan to set the traps in the spring or fall, if possible, preferably after a rain. During the winter and summer, moles stay deeper underground rather than surfacing. Therefore, they will be harder to trap during those times. Moles come above ground more frequently after a rain.
Open the trap and set the trigger. Follow manufacturer directions since there are several traps used to capture moles. Place traps on top of the active hole openings. They will trap the mole when it comes out of the ground and the trigger is set off. No baits are necessary.
