What Birdseed Do Squirrels Not Like?
Squirrels can be a nuisance at bird feeders, but there are specific types of birdseed they tend to avoid. What birdseed do squirrels not like? Typically, squirrels are not fond of seeds containing capsaicin (the compound that makes chili peppers hot) or certain seed types like nyjer (thistle seed).
Understanding the Squirrel-Bird Feeder Conflict
The allure of bird feeders is undeniable to squirrels. They are opportunistic feeders, always on the lookout for a convenient and readily available food source. Birdseed provides just that. Understanding this conflict is the first step in finding a peaceful resolution that allows both birds and squirrels to thrive in your backyard ecosystem.
The Power of Capsaicin: Spice It Up!
Capsaicin is the chemical compound responsible for the spicy heat in chili peppers. Birds are unaffected by capsaicin, but squirrels are highly sensitive to it. This presents a unique opportunity to deter squirrels without harming the birds you’re trying to attract.
- How to use it: You can purchase birdseed pre-treated with capsaicin, or you can add chili flakes or a cayenne pepper powder supplement to your existing birdseed mix. Start with a small amount and increase the dosage as needed to deter squirrels effectively.
- Important Safety Tip: Always wear gloves when handling capsaicin and avoid touching your eyes or face.
Nyjer (Thistle Seed): A Seed Too Small
Nyjer seed, often called thistle seed, is a tiny, oil-rich seed that is highly attractive to finches. However, squirrels are generally not interested in it. The small size of the seed and its oil content make it less appealing to their larger teeth and coarser appetites.
- Benefits: Nyjer seed is a great way to attract a variety of finches, such as goldfinches, purple finches, and house finches, while simultaneously discouraging squirrels.
- Considerations: Nyjer seed requires a special type of feeder with small feeding ports to prevent spillage.
Other Less Palatable Seed Options
While capsaicin-infused seeds and nyjer are the most effective, other types of seeds are less appealing to squirrels than sunflower seeds or corn.
- Safflower seeds: Some squirrels avoid safflower seeds, although it’s not a guaranteed deterrent. Birds like cardinals, chickadees, and doves often enjoy them.
- White-striped sunflower seeds: Squirrels often prefer black-oil sunflower seeds, so switching to white-striped can sometimes help.
Bird Feeder Modifications and Strategies
Beyond choosing the right seed, modifying your bird feeders and implementing strategic placement can further deter squirrels.
- Baffles: Install baffles above or below your bird feeders to prevent squirrels from climbing or jumping onto them.
- Squirrel-resistant feeders: Invest in feeders designed specifically to thwart squirrels. These feeders often have cages or weight-activated mechanisms that close off access to the seed when a squirrel tries to feed.
- Placement: Place bird feeders away from trees, fences, and other structures that squirrels can use to jump onto the feeder. A minimum distance of 10 feet is recommended.
- Offer a Distraction: Consider setting up a dedicated squirrel feeder with corn or peanuts. This can draw their attention away from the bird feeders.
Common Mistakes to Avoid
- Using too much capsaicin: Overdoing the spice can deter birds as well as squirrels. Start small and observe the birds’ behavior.
- Assuming all squirrels behave the same: Squirrel behavior can vary depending on the region and individual preferences. What works for one squirrel may not work for another.
- Giving up too easily: Deterring squirrels often requires persistence and a combination of strategies. Don’t get discouraged if your initial efforts are unsuccessful.
What Birdseed Do Squirrels Not Like?: A Summary of Effective Seeds
| Seed Type | Squirrel Preference | Bird Attracted | Notes |
|---|---|---|---|
| ———————- | ———————- | —————————————— | ————————————————————————————————————————————————————————————————————————————————————————————————————————– |
| Capsaicin-Infused | Highly Avoided | Varies depending on seed type | Extremely effective deterrent. Safe for birds. Wear gloves when handling. |
| Nyjer (Thistle Seed) | Not Preferred | Finches (Goldfinches, Purple Finches) | Requires a special feeder with small ports. |
| Safflower Seeds | Sometimes Avoided | Cardinals, Chickadees, Doves | Less reliable than capsaicin or nyjer. |
| White-Striped | Less Preferred | Varies depending on seed mix | Less attractive than black-oil sunflower seeds. |
| Black-Oil Sunflower | Highly Preferred | Wide variety of birds | Avoid if squirrels are a major problem. |
| Corn (Cracked) | Highly Preferred | Ground-feeding birds (Doves, Quail) | Avoid using this in bird feeders if squirrels are a problem. Best for dedicated squirrel feeding areas. |
Frequently Asked Questions
Will capsaicin hurt the birds?
No, capsaicin does not harm birds. They lack the receptors that make mammals sensitive to the chemical. This makes it a safe and effective way to deter squirrels without affecting your feathered friends.
How much capsaicin should I add to birdseed?
Start with a small amount, about a teaspoon of cayenne pepper powder per pound of birdseed. Observe the squirrels’ behavior and increase the amount as needed. Avoid overdoing it, as excessive spice could deter birds.
Is it safe to use chili flakes instead of cayenne powder?
Yes, chili flakes are a safe alternative to cayenne powder. However, they may not distribute as evenly throughout the birdseed mix. Consider grinding them up slightly before mixing.
Where can I buy birdseed treated with capsaicin?
Many birdseed suppliers offer pre-treated birdseed containing capsaicin. Check your local pet stores, garden centers, or online retailers specializing in bird feeding supplies.
Do all squirrels dislike nyjer seed?
While most squirrels are not particularly fond of nyjer seed, individual preferences may vary. Some squirrels may still try to eat it, although it is less appealing than other options.
How do I keep my bird feeder clean?
Regularly clean your bird feeder to prevent the spread of disease. Empty the feeder completely and scrub it with warm, soapy water. Rinse thoroughly and allow it to dry completely before refilling.
What is the best type of bird feeder to prevent squirrels?
Squirrel-resistant feeders are the most effective. These feeders often have cages or weight-activated mechanisms that close off access to the seed when a squirrel tries to feed.
Can squirrels learn to tolerate capsaicin?
Some squirrels may gradually become accustomed to capsaicin over time. If this happens, consider increasing the dosage or trying a different deterrent method.
What other animals are deterred by capsaicin?
In addition to squirrels, capsaicin can also deter other mammals, such as raccoons and deer. However, use caution when deterring other animals, as some may be more sensitive to capsaicin than squirrels.
Is it cruel to deter squirrels from bird feeders?
Deterring squirrels from bird feeders is not considered cruel as long as you use humane methods. Squirrels are resourceful animals and will find alternative food sources.
What are some natural alternatives to capsaicin for deterring squirrels?
Peppermint oil and other strong scents are sometimes used as natural squirrel repellents. However, their effectiveness can vary. A combination of strategies is often most successful.
Should I stop feeding birds if squirrels are a persistent problem?
You don’t necessarily need to stop feeding birds if squirrels are a persistent problem. By using the strategies outlined above, such as choosing the right seed, modifying your bird feeders, and implementing strategic placement, you can often find a way to enjoy bird feeding without attracting unwanted attention from squirrels.
