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 are far less sensitive to capsaicin, the natural compound that makes peppers hot, than mammals such as squirrels, raccoons, and chipmunks. That means birds can continue feeding while many mammals find the spicy coating unpleasant and move on.
For many backyard birdwatchers, hot pepper birdseed is one of the easiest and most effective ways to reduce squirrel activity without changing feeders or rearranging the whole yard.
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 one of the best birdseed options for discouraging squirrels.
The seed is coated with capsaicin, which many mammals find unpleasant while birds are much less sensitive to it.
Many birdwatchers find that squirrel activity drops significantly 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 are less likely to eat, hot pepper birdseed is one of the strongest options.
Unlike standard birdseed mixes, hot pepper blends are specifically designed to 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 calorie-dense and easy to eat, making feeders an especially attractive food source.
In fall, squirrels also spend more time gathering and storing food for the colder months ahead, so feeder activity can become even more noticeable.
If squirrels are constantly visiting your feeder, the seed itself may be part of the problem.
Does Hot Pepper Birdseed Really Work?
For many birdwatchers, yes.
Hot pepper birdseed works because birds and mammals respond differently to capsaicin.
Birds are much less sensitive to the heat, while squirrels and other mammals typically find it unpleasant.
As a result, many squirrels decide the feeder is no longer worth the effort.
Hot pepper birdseed can be especially useful if you want to reduce squirrel activity without buying a new feeder or completely changing your setup.
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 are far less sensitive to capsaicin than mammals, they can 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?
Commercial hot pepper birdseed is commonly used for backyard bird feeding and is designed to take advantage of the difference between how birds and mammals respond to capsaicin.
Birds are far less sensitive to capsaicin than squirrels and other mammals, which is why they typically continue feeding while mammals back off.
As with any birdseed, choose a quality blend intended specifically for wild birds and keep feeders clean and dry.
Is Fall a Good Time to Switch to Hot Pepper Birdseed?
Yes.
Fall can be an especially useful time to make the switch because squirrels are actively gathering and storing food as temperatures cool.
If your feeders suddenly seem busier with squirrels, changing the seed can be one of the simplest ways to reduce the competition without removing the feeders birds rely on.
Our Recommendation
If squirrels are driving you crazy, start with a quality hot pepper birdseed blend.
For many birdwatchers, it's one of the simplest ways 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.
