Squirrels in the day and coons at night. I tried Pam ,WD40, Furnature polish and it only lasted a couple days. The way I did it was to use 2 to 3 ft pieces of 3in thin wall PVC pipe and on the top edge opposite sides and drill drill a hole, in the holes put a spring on each side tie the other ends together with a piece of paricord about 8in long, slip them up over the legs and tie them to the top where the legs attach to the feeder. When they climb the legs and get to the PVC pipe and get ahold of it the springs will let the pipe come down and knock their back leggs off the feeder or it will rotate and throw them off balance. Bought every thing at LOWES. They would empty it in 3 days and now it last me 6 weeks. It works
