Squirrels are fascinating little creatures. You often see them darting across trees, nibbling on acorns, or raiding backyard bird feeders. But when it comes to giving them nuts as a snack, people usually stop and ask: should you offer pistachios or hazelnuts? Both nuts are popular with humans, but are they equally safe and healthy for squirrels? Let’s dig into a full breakdown.
Why Nuts Matter in a Squirrel’s Diet
Squirrels rely on nuts for energy, protein, and fats. Nuts are calorie-dense, which means squirrels get a lot of fuel from small amounts. This is vital because squirrels burn a lot of energy climbing trees, digging holes, and storing food for the winter.
Natural nuts like acorns, walnuts, pecans, and hazelnuts form a large part of their diet in the wild. But when humans step in with snacks like pistachios, the question becomes whether they provide the same nutritional benefits, or if they could pose risks.
Pistachios: Quick Overview
Pistachios are bright green nuts with a mild, slightly sweet flavor. They’re usually sold roasted and salted, though raw pistachios are also available. Humans love them for their taste and health benefits, but let’s see how they measure up for squirrels.

Hazelnuts: Quick Overview
Hazelnuts are round nuts with a rich, nutty flavor. You often find them in desserts like chocolate spreads, pralines, and baked goods. But in their raw form, hazelnuts are nutrient-packed and closer to what squirrels encounter naturally in the wild.

Comparing Pistachios and Hazelnuts for Squirrels
Now, let’s look at how each nut works for squirrels.
Protein levels
Pistachios edge ahead in protein, which helps build muscle and repair tissues. This makes them great for squirrels that are highly active.
Fat content
Hazelnuts have more fat, which is important in colder months when squirrels need to store energy. This fat is healthy, mostly unsaturated, and helps squirrels survive winter.
Carbohydrates
Pistachios contain more carbs. While squirrels do use carbs for quick energy, they mainly thrive on fats. This makes hazelnuts a bit more aligned with their natural diet.
Fiber
Both pistachios and hazelnuts contain fiber, which helps digestion. Fiber also gives squirrels a sense of fullness, so they don’t overeat.
Are Pistachios Safe for Squirrels?
Yes, pistachios are safe for squirrels, but only when raw and unsalted. The problem is that most pistachios sold in stores are roasted with salt. Salt is harmful to squirrels because it affects their hydration and can cause health problems.
Another issue is the shell. Pistachios come in hard shells, and while squirrels can crack them open, flavored or dyed shells should never be given. Always stick to raw, plain pistachios with no additives.
Are Hazelnuts Safe for Squirrels?
Hazelnuts are not only safe but also closer to what squirrels naturally eat. In fact, hazelnuts are one of their favorites in the wild. The shells of hazelnuts provide a challenge that keeps their teeth sharp, and the nutrient profile matches their needs.
Hazelnuts are also safer because they’re less likely to be sold heavily salted or flavored compared to pistachios.
Pistachios vs. Hazelnuts: Taste and Preference
If you’ve ever fed squirrels directly, you may have noticed that they get picky. Many squirrels go for hazelnuts first because they’re familiar with the shape and taste. Pistachios may be new to them, but once they crack the shell, they often enjoy them too.
From my own personal experience, squirrels in backyards usually hoard hazelnuts more than pistachios. They bury hazelnuts for later but tend to snack on pistachios right away.
Health Risks of Overfeeding Nuts
Even though nuts are good for squirrels, too much of anything can harm them. Nuts are high in calories, and overfeeding can lead to obesity in squirrels. This makes them less agile and more vulnerable to predators.
Too many pistachios or hazelnuts can also upset their stomachs. A few nuts as a treat is fine, but they should never replace the balanced diet squirrels get from seeds, fruits, and insects.
Which Nut is Better Overall?
If you’re choosing between pistachios and hazelnuts for squirrels, hazelnuts win. They’re more natural, richer in fat, and better suited to what squirrels would normally eat. Pistachios are fine in moderation but require more caution because of added salt or flavoring.
Think of pistachios as an occasional treat, while hazelnuts can be a more regular part of their snack rotation.
Feeding Tips for Squirrels
- Offer raw, unsalted nuts only.
- Keep portions small, just a few nuts a day.
- Avoid flavored, candied, or chocolate-coated nuts.
- Leave nuts in shells when possible. This gives squirrels natural chewing exercise.
- Mix nuts with seeds and fruits to balance their diet.
Do Squirrels Store Pistachios and Hazelnuts Differently?
Yes, they do. Hazelnuts are ideal for storing because their shells protect the nut inside, and they don’t spoil quickly. Pistachios, especially if shelled, don’t store as well. Squirrels may eat pistachios on the spot instead of hiding them away for later.
This behavior shows how squirrels instinctively know which foods are best for long-term survival.
The Human-Squirrel Connection
Many people enjoy feeding squirrels, whether in city parks or backyard gardens. While hazelnuts may cost more than pistachios, they make for a healthier, more natural choice. Plus, watching squirrels wrestle with hazelnut shells can be entertaining and satisfying.
Based on my overall experience, offering hazelnuts feels more rewarding because squirrels react with enthusiasm, often running off to stash them for future use. Pistachios, while enjoyed, don’t spark the same excitement.
Final Thoughts
So, pistachios vs. hazelnuts for squirrels? The answer is clear: hazelnuts take the crown. Pistachios are fine in moderation, but hazelnuts are safer, healthier, and closer to what squirrels would choose in the wild.
If you want to keep your furry backyard visitors happy and healthy, go with hazelnuts most of the time and save pistachios as a fun treat.
