I am sorry to hear you have a rodent problem (was that from Transformers).
I left the east coast thinking I would be away from pests. HA HA HA! I have killer gophers that have destroyed so many plants (bananas and anything else with roots!).

I have tried Critter Ridder from Havahart for my resident skunks. It does say on the container it repels squirrels.
Good luck!
