If squirrels are already part of your backyard routine, the best “food” for them is usually not a heaping bowl of peanuts. It is a yard with trees, shrubs, clean water, and enough natural forage that they do not learn to treat your patio like a drive-through window.
That said, plenty of homeowners want to support the wildlife they enjoy watching. The trick is knowing what actually helps squirrels, what only feels helpful, and what can turn a cute backyard visitor into a chewed-rafter, raided-bird-feeder, garden-digging problem.
Here is the practical version: wild squirrels do best with nuts, seeds, tree fruit, buds, mushrooms, tender plant matter, and the occasional insect they find themselves. If you supplement, keep it small, plain, and occasional. Skip bread, salted snacks, candy, processed cereal, and anything moldy. Your goal is to support natural behavior, not replace it.
What wild squirrels naturally eat
Most backyard squirrels are opportunists. They do not follow one tidy menu. They adjust to the season, the trees nearby, the bird feeders they can reach, and whatever your neighborhood accidentally provides.
A healthy wild squirrel diet usually includes:
- Tree nuts: acorns, hickory nuts, walnuts, beechnuts, pecans, and hazelnuts when available.
- Seeds: sunflower seeds, pine seeds, maple seeds, and other natural seed sources.
- Fruit: apples, pears, berries, crabapples, mulberries, and other small seasonal fruit.
- Plant material: buds, shoots, tender leaves, flowers, roots, and some garden greens.
- Fungi and insects: small seasonal extras that add protein and minerals.
This variety matters. A squirrel that gets most of its calories from one easy human-provided food can become nutritionally lopsided and more comfortable pushing into places you do not want it — feeders, sheds, attic edges, trash cans, and garden beds.
The best foods to offer wild squirrels, if you choose to feed them
If you are going to put food out, think “small sample of natural foods,” not “daily buffet.” The best supplemental foods are plain, unsalted, and close to what squirrels would recognize outdoors.
| Food | How to use it | Watch-out |
|---|---|---|
| Acorns, walnuts, hazelnuts, pecans | Best occasional supplement, especially in fall and winter. | Use plain nuts only. No salt, sugar, roasting oil, chocolate, or seasoning. |
| Sunflower seeds | Useful in small amounts; often already present around bird feeders. | Too many can crowd out better variety and attract feeder raiding. |
| Apple, pear, berries | Offer small pieces, then remove leftovers before they spoil. | Fruit ferments and attracts insects if left out. |
| Carrot, squash, leafy greens | Good low-drama additions when you want variety. | Do not pile up wet vegetables where they can rot. |
| Clean water | Often more useful than extra food during hot, dry spells. | Refresh daily so it does not become a mosquito nursery. |
One practical rule: put out less than you think you need. If food is still sitting there later in the day, you offered too much. Leftovers invite rats, raccoons, ants, flies, and neighborhood drama. The squirrels will not be the only guests reading the menu.
Foods you should not feed wild squirrels
Squirrels will eat plenty of things that are not good for them. That is not a recommendation; it is just squirrel decision-making, which is impressive in athletic terms and questionable in dietary ones.
- Bread, crackers, popcorn, and cereal: filling, low-value foods that can crowd out better nutrition.
- Salted or flavored nuts: too much sodium and seasoning for a small animal.
- Chocolate, candy, cookies, and pastries: not wildlife food, even if a squirrel will absolutely try to prove otherwise.
- Moldy nuts, spoiled fruit, or damp seed: unsafe for wildlife and excellent at attracting pests.
- Avocado skin/pit, onions, garlic, and heavily processed leftovers: skip the kitchen-scrap experiment.
Also be careful with peanuts and corn. Plain peanuts are not poisonous in the normal sense, but they are not the gold standard either. Use them sparingly, preferably mixed with better options. Corn can be part of some commercial wildlife mixes, but big piles of dried corn are more likely to attract rodents and raccoons than to create a healthier squirrel population.
Seasonal feeding: what matters by time of year
Squirrel behavior changes a lot with the calendar. Match your expectations to the season instead of treating every month like feeder season.
Spring
Spring squirrels are busy with buds, shoots, early greens, stored nuts, and nest work. This is a good time to focus on habitat instead of handouts. If squirrels are digging in fresh planting areas, do not reward the exact spot with food. Use mulch, hardware cloth over vulnerable containers, and better feeder placement instead.
Summer
Summer provides fruit, seeds, insects, and plenty of natural forage. A shallow water dish may help more than food during hot dry stretches. Keep it away from doors, grill areas, and bird feeders so you are not teaching squirrels to patrol the highest-conflict parts of the yard.
Fall
Fall is squirrel grocery season. They cache acorns and nuts, raid easy food sources, and become extremely interested in anything calorie-dense. If you have oak, hickory, walnut, or beech trees, you may not need to feed at all. If bird feeders become the problem, start with placement and baffles before trying to distract squirrels with a second food source.
Winter
Winter is the only season where small supplemental feeding can make more sense, especially during ice, deep snow, or unusual scarcity. Keep it occasional. A few plain nuts and clean water are better than a large daily pile that trains squirrels, raccoons, and rodents to check your patio every morning.
How to feed squirrels without creating backyard problems
If your goal is peaceful wildlife watching, the setup matters as much as the food. Feeding in the wrong place can create damage, feeder wars, and a squirrel that gets far too comfortable near your house.
- Keep food away from the house. Do not feed on the deck rail beside a door, under eaves, near attic vents, or beside a garage.
- Separate squirrel food from bird feeders. If the feeder is the main conflict, read the guide to squirrel-proofing your bird feeder before adding more food to the system.
- Use a small washable dish. Scattered food disappears into mulch and becomes pest bait.
- Remove leftovers. If it is not eaten by evening, clean it up.
- Stop feeding if damage increases. Chewed wood, torn screens, attic noise, and repeated garden digging mean the yard needs boundaries, not more snacks.
If squirrels are already causing trouble, start with the damage pattern. This guide to spotting squirrel damage around the home can help you tell normal backyard activity from chewing, nesting, or entry-point behavior that needs attention.
A better long-term plan: feed the habitat
The most useful thing you can do for squirrels is also good for birds, pollinators, shade, and the overall feel of the yard: grow more real habitat.
- Leave some acorns or natural mast under trees instead of clearing every last one.
- Add native shrubs that produce berries or cover.
- Plant oak, hickory, serviceberry, crabapple, or other region-appropriate food trees where space allows.
- Keep a clean water source during dry periods.
- Use bird feeding strategies that reduce conflict rather than turning feeders into squirrel training equipment.

Quick answer: what is the best food for wild squirrels?
The best foods for wild squirrels are natural, plain foods they would reasonably encounter outdoors: acorns, walnuts, hazelnuts, hickory nuts, seeds, small pieces of fruit, vegetables, and clean water. The best overall approach is even simpler: improve the habitat, keep bird feeders protected, and only supplement lightly when it truly helps.
If feeding starts causing damage, feeder raids, digging, or too many animals gathering in one spot, pause the food and fix the system. A backyard that works well for wildlife should still work for the people who live there.
