ironpony said:several tears back I had aproblem with someone knocking over my bird feeder
what I did was, got a pressure tank, filled it with red dye and pressurized to 100 psi
i then wired a micro switch the the bird feeder and a solenoid on the tank
installed a sprinkler head with a round pattern and hid it all
when they came back and knocked over my bird feeder the micro switch tripped,
spraying red dye in a roughly 8 foot circle covering whoever it was in red dye
never did find them, but it never happened again
Red squirrels probably make an easy target for predators.
