Moles can wreak havoc in your garden. The woodland animals often colonize and spread. They create a tunnel system under ground to get around. so you may not even see them destroying your plants and flowers. They work from under the ground, destroying the roots and bulbs. If you leave that tunnel in place, moles will develop habits and become very difficult to capture or kill.
Check with local and state authorities to determine if your state will let you use deadly traps to get rid of moles from the garden. Some states do not allow this. The Department of Wildlife may be able to help you.
Search out the tunnel system the moles are using. Look for piles of dirt in your yard, which indicate the digging point underground. Move the soil aside and insert a stick into the ground to see if there is an open tunnel underneath.
Put a mole trap in the center of the tunnel so the animal steps into it. The trap will impale or choke the mole once it makes contact.
Opt for poison if the state won't let you use traps. Buy poisoned bait that looks like earthworms, which are the mole's main source of food. The bait contains bromethalin, which will kill the pest in 24 hours. Put the poisonous worms in the mole's tunnels so they eat them.
Make a homemade concoction to kill moles. Combine 1 cup of Murphy's Oil Soap with 1/4 cup of cayenne pepper and 1 oz. of castor oil. Mix it with water to formulate a 2-to-1 mixture. Fill a spray bottle with the poison and spray the spots you know the moles travel. You can also pour it right into the mole tunnel.
