Lawn moles, according to Michigan State University, are mammals of the order Insectivora, meaning they are insect eaters. There is no place greater to find insects than in the earth, and moles dig tunnels throughout yards and gardens in the hunt for their delicacy. If left to wreak havoc, moles will dig tunnels at a rate of 15 feet per hour. Trapping and killing moles can be difficult, but the right trap will fool moles every time.
Crush a few mole tunnels by stepping on them to find out which tunnel is still active. Check the tunnels in the morning to see which are rebuilt.
Fill a glass jar with 7 inches of water.
Attach a piece of hard candy or gum to a string attached to the jar. Hang the candy just above the level of water. Wear gloves while preparing the jar so that you do not transfer your smell to the jar, as this will frighten a mole away.
Dig a hole in an active tunnel wearing gloves, digging down until the jar will fit in the hole at the bottom. The lip of the jar should be level with the bottom of the tunnel. Cover the sides of the jar with dirt before placing it in the tunnel to remove your scent.
Cover the top of the tunnel with a piece of wood and wait until the next day. Check the trap daily. A mole that falls into the jar will drown in the water.
