Squirrel Feeder
Wooden platform that holds a cob of corn.
After whatever is done to remove squirrels, repair house to prevent entry from critters again, get one of these Squirrel Feeders.
Local Mom & Pop Hardware Store, Feed & Seed Supply, Tractor Supply - etc.
One sets these away from structures they do not want squirrels to get into.
Like houses, sheds, barns and the like. Squirrels are attracted to these, and not houses and the other structures.
I recommend finding a spot where one can watch from indoors, as this can be entertaining, and educational. Especially if one has kids.
A few neighbors doing this, will assist in controlling squirrels amongst neighbors.
These make nice gifts as well.
