Canada Geese doing damage during our snowbirding down south

I live in a seaside town, and building owners around here use parallel wires to deter seagulls- should work for geese, too.

Drive some tall stakes into the dirt at each corner of the box and string some real thin wire between them. (The wire should be about a foot above the surface of the planter top/soil surface). Geese can't sit on the wire, and can't get to the box because it's there.
