Stop moles from tunneling underneath your property and causing unsightly damage to your lawn and yard. The Tomcat Mole Killer(a) worm baits are mole killers that mimic the mole's natural food source - the earthworm - in both shape and feel. Moles may consume a lethal dose in a single feeding, but it may take two or more days from the time of bait consumption for moles to die. This ready-to-use mole bait is effective against most common mole species (not for use against the star-nosed mole in North Carolina). You may have moles in your front yard or backyard lawn if you notice these signs: subsurface runways in your lawn, or a series of conical mounds. This mole yard killer is used to kill moles in their underground tunnels by placing the worm bait on active runways. Once active runways are verified (the step-by-step instructions on the label will help you out), make a hole in the top of the runway then drop one bait worm into the opening, ensuring it is completely underground and the hole is carefully resealed. Repeat every 5-10 feet along runways. Five to seven days after application, DIY homeowners should check again for mole activity to help reduce mole mounds from forming. One package of Tomcat Mole Killer(a) contains 10 worm baits.
