One of the most destructive pests that can invade your yard is the common mole. Moles can ruin your yard and garden by digging tunnels everywhere beneath the surface of the soil. The tunnels can cause the ground to soften, and even cave in areas of heavy activity. Moles will also eat the roots of garden plants, which can kill the plants without you even knowing what is happening. You can employ several methods to remove or even kill moles, one of which is to flood them out of their tunnels with a garden hose.
Locate an active mole tunnel by looking for a mole hill with loose dirt at the end of the tunnel.
Attach a garden hose to an outdoor faucet. Unscrew the nozzle from the other end of the hose if one is attached.
Insert the end of the garden hose down into the mole tunnel as far as you can (several feet) so that the force of running water doesn't eject it from the mouth of the tunnel.
Place a brick or large rock over the hose next to the tunnel. The brick will help keep the hose in place once you turn on the water.
Place another garden hose in any other active tunnel you can find in the immediate area. The more water you can pump into the tunnels at once, the better chance you have of flushing out the mole or drowning it.
Turn the water faucet all the way on. Make sure the hose does not pop out of the tunnel. If you are using more than one hose, have a friend turn the other faucet on at the same time.
Observe the area around the tunnel opening for a mole to surface.
Place any mole you catch in a bucket filled with soil, and transplant it to a field or wooded area.
Turn off the water after a few minutes. You don't want to flood your yard or your house if the tunnels are close to a basement.
Check the dirt on the mole hill and see if it is loose and fresh. Fresh dirt means that the mole is currently using that particular tunnel. Avoid any tunnels where the mole hill dirt is packed down and shows no signs of activity.
