How to Keep Squirrels Off Bird Feeders: Methods That Work

Squirrels reach bird feeders in three ways: they climb up, they jump across, or they drop from above. Block all three and they give up. That is why a smooth pole with a baffle, standing well away from trees and roofs, does more than any single gadget, and why a "squirrel-proof" feeder hung from a tree branch so often disappoints.

Everything below is humane. No poisons, no traps, no greased poles; those harm birds and other wildlife as much as squirrels.

Know what you're up against

A gray squirrel can jump roughly 4 to 5 feet straight up from the ground and leap 8 to 10 feet across from a branch, fence or roof. It will happily drop onto a feeder from a limb above. It climbs wood, brick, wire and thin poles with ease, and it learns: once a squirrel finds a route to your feeder, it will test that route every day.

Those distances are the whole game. A defense that ignores them will fail, however clever it looks.

Methods ranked by how well they work

1. A baffled pole in the right place

Mount the feeder on a smooth metal pole and add a baffle below it, either a wide cone or a stovepipe-style cylinder. Where you put the pole matters as much as the baffle itself:

• The bottom edge of the baffle should sit at least 4 feet off the ground, and 5 feet is safer.
• The pole should stand 8 to 10 feet or more from trees, fences, deck rails, roofs and anything else a squirrel can launch from.
• Nothing should overhang the feeder. A branch above it is a drop point.
• In snowy regions, remember that a drift under the pole raises the ground a squirrel jumps from. Keep the snow cleared or mount the baffle higher.

Step-by-step measurements are in how to place a squirrel baffle.

2. Weight-activated feeders

These feeders have a perch or outer shroud on a spring. A small bird's weight doesn't move it; a squirrel's does, and the seed ports close. Better models let you adjust the setting so cardinals and jays can still eat. They work well, with two catches: the squirrel still gets whatever the birds drop, and on a poorly designed feeder it may hang from the roof and reach the ports without touching the perch. What separates good designs from weak ones is covered in what makes a bird feeder squirrel-proof.

3. Cage feeders

A wire cage around a tube lets chickadees, finches, titmice and other small birds reach the seed while holding squirrels at arm's length. The same cage can exclude bigger birds you may want to see, and if the cage sits too close to the tube, a squirrel can sometimes reach through it.

4. Seed squirrels care less about

Safflower, a white seed with a bitter taste, is eaten by cardinals, chickadees, titmice, House Finches and Mourning Doves, while many squirrels pass it by. Nyjer in a finch feeder rarely interests them either. Neither is a sure thing, since a hungry squirrel may eat safflower anyway, but swapping out sunflower takes away the main reason to visit. See bird food squirrels won't eat.

5. Hot pepper seed and suet

Birds don't register capsaicin, the compound that makes peppers hot, the way mammals do. Seed and suet treated with hot pepper are sold for exactly this purpose. Buy them ready-made rather than dusting seed with pepper powder yourself, wear gloves when you fill the feeder, and keep your hands away from your eyes.

6. Dome baffles on hanging feeders

A wide dome above a feeder only helps if a squirrel can't simply jump onto the feeder from the side. Hang the feeder 8 to 10 feet out from the trunk, or string a wire between two trees and hang it in the middle of the span with the dome above it.

7. Give squirrels their own spot

Some people put ear corn or peanuts in the shell at a separate station well away from the bird feeders. It keeps some squirrels busy, but it can also bring more of them to the yard, so treat it as an extra, not a replacement for a baffle. The pros and cons are weighed in should you feed squirrels separately.

What doesn't work, and what never to do

• Grease, oil or petroleum jelly on the pole. It gets onto fur and feathers, which lose their insulation and waterproofing, and it wears off quickly anyway. Use a baffle instead.
• A "squirrel-proof" feeder hung from a tree. The feeder may hold out, but the squirrel will eat everything that falls, and it may chew through plastic parts to get more.
• Plastic owls and ultrasonic devices. Squirrels quickly get used to a decoy that never moves. Don't count on noise devices either.
• A thin pole with no baffle. Squirrels climb it easily.
• Trapping and moving squirrels. Rules vary by state and often require a permit, it is hard on the animal, and another squirrel usually moves into the empty territory.
• Poison or glue traps. Never. They kill birds, pets and other wildlife, and they cause great suffering.

A combined plan that works

1. Move the feeder to a spot at least 8 to 10 feet from every launch point, with nothing overhead.
2. Mount it on a smooth pole with a baffle whose lower edge sits 4 to 5 feet up.
3. Choose a weight-activated or caged feeder if your squirrels are especially acrobatic.
4. Fill it with safflower, or with hulled sunflower so less seed gets flicked to the ground.
5. Clean up spilled seed under the feeder every few days so squirrels have no reason to hang around.
6. Give it two weeks. Squirrels test every new setup; once each attempt fails, most stop trying.

If squirrels still get through

Watch for a morning and see exactly how they get on. The answer is almost always one of these:

• A launch point you missed: a bench, grill, trash can, lawn chair or woodpile within jumping distance.
• A baffle mounted too low, or snow piled up beneath it.
• A branch that has grown out over the feeder since last year.
• A pile of seed below the feeder that keeps them nearby and motivated.

Fix that one gap and the rest of the setup usually holds. If you have been tempted to grease the pole in the meantime, read why petroleum jelly on a feeder pole is a bad idea first.
