We love watching frolicking squirrels in our yard and every year we buy bags of corn for them to snack on. We draw the line when they climb up to feeders and gobble expensive seeds meant for chickadees, nuthatches, and woodpeckers.

Bird feeder companies all tout their “squirrel proof” feeders and a homeowner can spend a bundle on different feeders just to slow the flow of seed from feeder to squirrels’ mouths. Some preventions work better than others but a reliable company is Droll Yankee.

But, being partly of Yankee stock, we took the economical route. To thwart the hungry mammals we mounted our feeders on steel pipes and even ringed some with metal stove pipe. Somehow they managed to dig claws into the metal, climb and feast on expensive seed.

Then we discovered spray grease. It’s sold in hardware stores and is meant to spray on drawer slides, hinges, and other balky metal parts. We sprayed it on the metal pipes holding up the feeders. Squirrels gingerly put their feet on the pipe and backed off as soon as they felt the grease. It works.

Spray grease only lasts a few weeks and needs to be reapplied, but it is a simple way to discourage squirrels from climbing to feeders.
