How to Kill Moles with Worms
Keep your lawn and garden healthy by killing moles with fake gel worms. (grass,lawn image by Greg Pickens from

Moles sometimes wreak havoc on a lawn and garden. They are more prevalent where there is a plentiful supply earthworms, one of their primary sources of food. If you'd rather not handle the dead moles that trapping would require, use special gel worms instead. They have a similar feel to fake fish worms and are coated with poison. There are several brands of these gel worms available, each of which is used according to its manufacturer's directions, but in general they are employed in a similar manner.

Skill level:

Things you need

  • Pencil or rod
  • Rubber gloves
  • Poison gel worms

  1. 1

    Locate the moles' active tunnels. To check which tunnels are active, push down the raised dirt in several areas along the moles' trails. Mark the areas where you push down the dirt with sticks or flags. Check in two or three days to notice if the earth has popped up in the marked areas. The areas that re-expand are active tunnels.

  2. 2

    Purchase fake poison gel worms made to kill moles. They often come in packs of 10. You'll need one worm for every 5 to 10 feet of active tunnels, but check the packaging for the exact distance you should leave between worms.

  3. 3

    Wear rubber gloves to open the gel worm packets and to handle the worms. This prevents human scent from transferring to the worms, which would reduce the bait's effectiveness.

  4. 4

    Insert a thick pencil or rod (one that's just slightly wider than the worms) into the raised soil just below the surface along the active tunnels. Push the worm in and cover the bait with dirt. Repeat with a new gel worm every 5 to 10 feet along active trails. No light should filter through the hole or the moles will not take the bait.

  5. 5

    Check the mole tunnels to see if they're still active in about a week. Also check for any new tunnels that popped up in the meantime. If necessary, apply new gel worms.

Tips and warnings

  • Gel worms are poisonous to pets and children and should not be used around them.
