First the M/F's got into my generator case and ate the insulation and wiring. Solved that problem with sealing the case everywhere but air intake and exhaust, fine screens there. Lined the floor with glue traps. picked up all the insects and 2 mice.
This past winter, they decided the outside generator was no longer safe so they ate through the rubber seal on the center garage door (stand alone building) and starting attacking the cars and trucks. Nothing as bad as CCS, but what I was shocked at was I left the Tahoe on the lift all winter - 6' in the air and yet there was evidence they were in the HVAC ductwork and glovebox, WTF?
Traps, poison and glue traps everywhere now. We have no kids or pets, so don't need to worry about ancillary harm.
