Controlling Moles Moles can be the most common and frustrating lawn pest problem. The animals eat soil insects such as grubs and earthworms. They do not feed on flower bulbs or plant roots. There is currently no satisfactory chemical control. Trapping is at present the best technique for mole control.
Moles have two types of tunnels.
One type is used only once, the other type is used regularly. The trap must be set on those tunnels the moles use regularly. A less scientific method is available when the tunnels can be observed for a day. Step on those regularly used tunnels so they are completely pushed down. Look at the tunnels often through the day.
