Squirrel-proof bird feeder
If you are a birdwatcher or bird enthusiast, you probably own a bird feeder—a tiny house for your guest birds to visit and sing in your garden. But as with any home, unwanted guests may come-hungry squirrels.
While birds will eat a few grains of food, a squirrel may make a feast with whatever is inside. If you spray WD-40 on the pole, these little intruders won’t be able to climb it. The unwanted squirrel guests will pointlessly slide down every attempt they take at the feeder.
