How to Keep Squirrels Out of Your Bird Feeder

Few things frustrate bird lovers more than squirrels raiding their feeders. Agile, persistent, and surprisingly clever, squirrels can quickly empty a feeder meant for your feathered friends. While it may seem like a never-ending battle, there are proven strategies to keep squirrels away and ensure your feeders remain for the birds.

At Trail Optics, we know protecting your feeders is just as important as choosing the right food. Here’s how you can outsmart squirrels and enjoy uninterrupted birdwatching.

Why Squirrels Love Bird Feeders

Squirrels are opportunistic eaters. Bird feeders provide an easy meal rich in seeds, nuts, and suet — all foods they naturally crave. Once they discover a food source, they return again and again, often scaring off birds and causing waste.

The key is not to eliminate squirrels completely (they’re part of the ecosystem), but to minimize access so your feeders remain primarily for birds.

Strategies to Keep Squirrels Away

Use Squirrel-Proof Feeders

Specially designed feeders prevent squirrels from accessing seed. Some have weight-sensitive perches that close feeding ports under a squirrel’s weight, while others use cages to block larger animals.

Add a Baffle

A squirrel baffle — a dome or cone-shaped guard placed on a feeder pole — makes it nearly impossible for squirrels to climb past. Position it 4–5 feet above the ground for best results.

Choose Strategic Placement

Squirrels can leap 8–10 feet horizontally and about 4 feet vertically. Place feeders at least 10 feet from trees, fences, or overhangs to keep them out of reach.

Select Seeds Wisely

Certain seeds are less appealing to squirrels. Nyjer seed and safflower seed are favorites for birds like finches and cardinals but less attractive to squirrels. We love buying our Nyjer seeds from Chuck and Don's! 

Keep Feeders Clean and Steady

Spilled seed on the ground can invite more squirrels (and other pests). Use a feeder with a catch tray or regularly clean beneath feeders to reduce temptation.
