Easy way to keep raccoons out of your garbage.

A device to deter raccoons and keep animals away from your garbage cans and garden is the Sonic Shield from Bird B Gone. This little pest deterrent can be mounted on patios, decks, balconies and in the yard.

The Sonic Shield has a motion detector to set off a barking dog sound along with a flashing light during the day. At night you can set it to just the strobe light.
It is run on 4 AA batteries and designed to be left outside.
