If squirrels are eating all your birdseed, you're probably wondering:
What is the best bird seed to stop squirrels?
The short answer is hot pepper birdseed.
Birds cannot taste capsaicin, the natural compound that makes peppers hot. Squirrels, raccoons, chipmunks, and other mammals can. That means birds continue feeding normally while squirrels quickly decide your feeder isn't worth the trouble.
For most backyard birdwatchers, hot pepper birdseed is the most effective and easiest solution for squirrel problems.
What Bird Seed Do Squirrels Hate?
Squirrels are known for eating almost anything, but a few types of birdseed are much less appealing to them:
1. Hot Pepper Birdseed
Hot pepper birdseed is widely considered the best birdseed to stop squirrels.
The seed is coated with capsaicin, creating a spicy taste that mammals avoid but birds cannot detect.
Many birdwatchers find that squirrel activity drops dramatically after switching to a hot pepper blend.
2. Safflower Seed
Safflower has a naturally bitter taste that many squirrels dislike.
Cardinals, chickadees, titmice, nuthatches, and grosbeaks often eat safflower readily.
While safflower can help, some persistent squirrels eventually learn to tolerate it.
3. Nyjer Seed
Nyjer seed is popular with goldfinches and other small finches.
Because the seeds are tiny and less appealing to squirrels, they are often left alone.
Best Bird Seed Squirrels Won't Eat
No birdseed is guaranteed to stop every squirrel.
A determined squirrel can surprise you.
However, if your goal is to find birdseed squirrels won't eat, hot pepper birdseed consistently produces the best results.
Unlike standard birdseed mixes, hot pepper blends actively discourage mammals from feeding.
Why Do Squirrels Love Regular Birdseed?
Many traditional birdseed mixes contain ingredients squirrels love, including:
• Black oil sunflower seeds
• Peanuts
• Sunflower hearts
These foods are highly attractive to squirrels because they are rich in calories and easy to eat.
If squirrels are constantly visiting your feeder, the seed itself may be part of the problem.
Does Hot Pepper Birdseed Really Work?
Yes.
Hot pepper birdseed works because birds and mammals experience peppers differently.
Birds lack the receptors needed to feel the burning sensation caused by capsaicin.
Squirrels do not.
As soon as squirrels taste the seed, most decide to look elsewhere for food.
Many backyard birdwatchers report that hot pepper birdseed is the single most effective change they make to reduce squirrel activity.
What Birds Eat Hot Pepper Birdseed?
One of the biggest misconceptions about hot pepper birdseed is that birds won't eat it.
In reality, many backyard favorites readily eat hot pepper blends, including:
• Northern Cardinals
• Chickadees
• Tufted Titmice
• White-breasted Nuthatches
• Downy Woodpeckers
• Hairy Woodpeckers
• Blue Jays
• Finches
Because birds cannot taste the heat, they continue feeding normally.
How to Keep Squirrels Away From Bird Feeders
The best birdseed to stop squirrels works even better when combined with a few simple strategies:
Use a Squirrel Baffle
A properly installed baffle can prevent squirrels from climbing feeder poles.
Move Feeders Away From Launch Points
Place feeders at least 10 feet away from trees, fences, decks, and roofs whenever possible.
Choose a Squirrel-Resistant Feeder
Weight-activated feeders close access to seed when a heavier animal climbs on.
Keep the Area Clean
Spilled seed beneath feeders often attracts squirrels and other unwanted visitors.
Is Hot Pepper Birdseed Safe for Birds?
Yes.
Birds are not sensitive to capsaicin and do not experience the burning sensation mammals do.
In fact, wild birds regularly consume peppers and help spread pepper seeds in nature.
Hot pepper birdseed simply takes advantage of a natural difference between birds and mammals.
Our Recommendation
If squirrels are driving you crazy, start with a quality hot pepper birdseed blend.
For many birdwatchers, it's the simplest and most effective way to enjoy cardinals, chickadees, woodpeckers, nuthatches, and other backyard birds without constantly refilling feeders emptied by squirrels.
The goal isn't to hurt squirrels.
It's to make your bird feeder more attractive to birds and less attractive to everything else.
