It's a terrible feeling when you look out and see your beautiful lawn crisscrossed by a web of tunnel mounds. Moles make a horrible mess of your yard. If they've invaded, you can take measures to take back your lawn
To help prevent mole infestations from occurring in the first place, make your yard as mole-unfriendly as possible. One of moles' primary food sources is worms. To help prevent mole infestations from occurring in the first place, make your yard as mole-unfriendly as possible. Use products that control grubs and insects in your lawn to limit moles' food supply. Moles like soft damp earth, so avoid over-watering your lawn; a deep watering once a week should be enough to keep your lawn healthy without welcoming moles.
There are two very effective ways to kill moles - baiting and trapping. TOMCAT provides both options to meet your specific needs and preferences.
Traps: The TOMCAT Mole Trap provides a method to kill quickly and hold the mole to provide proof for tracking. Unlike many competitive spear traps, the TOMCAT Mole Trap does not draw blood, and it is safer and easier to use than traditional traps. For more information on setting, see How To Use TOMCAT Mole Trap.
Baits: TOMCAT Mole Killer Earthworm and Grub Formulas kill moles underground in the runway. Since the bait mimics the mole's natural food sources, earthworms and grubs, they eat the bait and die quickly underground in tunnels. In many cases, it is not necessary to see the mole or dispose of it. For more information on using baits, see How To Use TOMCAT Mole Killer Earthworm Formula.
You'll have more luck if you trap in the spring or fall, and if you set your traps in a main runway. These are usually straight, or they can follow the perimeter of your yard. To make sure you're working with a main runway, poke your finger through in a few spots. If the mole repairs the damage in a day or two, you've got a winner.
