Moles can become a pest at anytime of the year. They eat grubs and earthworms but do not feed on flower bulbs or plant roots. They are the animals that make your yard look like a war zone.
There is no chemical means to control moles except to kill the grubs and earthworms that they eat. The only option is to trap the moles. 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. When the tunnel is being pushed up, turn on the garden hose and push it into the tunnel near where the mole is working. The mole will be forced to the soil surface where it can be killed.
If you need someone else to take care of your mole problem, there is actually a company in Niles which will come out and trap your moles called Wild Animal Services.
