What's Eating My Pecans?
The Surprising Suspects You Need to Know About
You head out to your pecan tree one morning, coffee in hand, ready to admire your hard work — and half the nuts are just gone. It's frustrating, I know. Your first thought might be neighborhood kids, but more often than not, animals or insects are the real culprits behind your pecans being eaten. Let's walk through the usual suspects together.
I've talked to dozens of home gardeners who swear they've seen raccoons climbing trees at dusk or squirrels running off with nuts right in front of them. The truth is, pecans are a magnet for wildlife — they're packed with fat and protein, making them a perfect snack for everything from birds to bugs. If you've noticed your crop disappearing day by day, don't panic. You just need to identify the pest, then take action. In this guide, I'll help you figure out what's eating your pecans and give you practical steps to protect your harvest. We'll cover animals, insects, signs to look for, and prevention tips that actually work in real gardens.
Why Pecans Are Such a Target
Think about it from a pest's perspective: pecans are easy to access, delicious, and full of energy. Birds, squirrels, and insects don't care about your dinner plans — they just see a free meal. That's why pecans being eaten is such a common problem in backyard orchards across the US.
Let me give you a real example. A friend of mine in Georgia planted three pecan trees five years ago. Last fall, he watched a single squirrel carry off over half a pound of pecans per day for two weeks straight. That's roughly 7 pounds of nuts lost to one animal! Now, he uses baffles on his tree trunks and has seen a huge improvement. Understanding the pest is the first step to solving the problem. You wouldn't treat a spider bite with an antibiotic meant for a cold, right? Same logic applies here. Once you know what's eating your pecans, you can choose the right solution.
Animals That Eat Pecans

Squirrels: The Obvious Culprit
Let's start with the most common troublemaker. Squirrels are relentless. They don't wait for the nuts to ripen — they start harvesting as soon as the pecans begin to develop. One squirrel can easily damage or carry off about half a pound of pecans per day. That adds up fast when you have a family of them living nearby.
I've seen squirrels chew through plastic netting, squeeze under metal guards, and even gnaw through thin branches to get at pecans. They're smart, persistent, and incredibly efficient. If your pecans are being eaten and you spot small bite marks on the shells or half-eaten nuts scattered on the ground, squirrels are your prime suspect. To manage them, try installing a metal baffle on the tree trunk at least 6 feet off the ground — this stops them from climbing up. You can also trim overhanging branches that give them a jumping-off point from nearby trees or buildings. Another trick? Provide a separate food source, like a corn feeder placed far from your pecan tree. This won't stop them entirely, but it might distract them enough to save some of your crop.
Birds: Crows, Blue Jays, and More
You might not think of birds as pecan eaters since the nuts are so big, but they absolutely are. Birds don't usually attack until the shucks split open — that's when the nut inside becomes exposed. Once that happens, a flock of crows can devastate your entire harvest in just a few days. Each crow can eat up to one pound of pecans per day.
I remember a story from a gardener in Texas who lost nearly 80% of his crop to a group of crows over one weekend. Blue jays are also known to steal pecans, though they eat less per bird. But here's the thing: birds work together. One crow will call out to others, and within minutes, you have a whole flock feasting on your tree. If you notice pecans being eaten right after the shucks split, birds are likely the cause. To protect your tree, try covering it with bird netting before the nuts mature. You can also hang reflective tape or old CDs from the branches — the flashing light scares birds away. Motion-activated sprinklers work surprisingly well too, and they're humane. Just remember to set them up before the damage starts.
Other Animals: Raccoons, Possums, and More
Birds and squirrels aren't the only animals that enjoy pecans. Raccoons are particularly crafty — they can climb trees, open latches, and even work together to knock nuts to the ground. Possums are less destructive but will still help themselves to fallen pecans. Mice, hogs, and even cows have been known to eat pecans if they have access.
Let me share a quick comparison to help you identify which animal is causing the trouble. Raccoons leave behind broken branches and scattered shells, while possums usually just eat the nuts that have already fallen. Hogs can root up the ground around the tree, disturbing the roots. If you live near farmland, cows might wander over and nibble on low-hanging branches. Each animal leaves different signs, so pay attention to what you find. For raccoons, a sturdy fence around the tree or electric wire can help. For mice, keep the area clean of fallen nuts and debris. Prevention is always easier than cleanup, so start early.
| Animal | Daily Pecan Consumption (approx.) | Signs of Damage | Best Prevention |
|---|---|---|---|
| Squirrel | 0.5 lb (227 g) per squirrel | Bite marks on shells, half-eaten nuts on ground | Metal baffle on trunk, branch trimming |
| Crow | Up to 1 lb (0.5 kg) per crow | Split shucks, missing nuts from upper branches | Bird netting, reflective tape, motion sprinklers |
| Raccoon | About 0.3-0.5 lb per visit | Broken branches, scattered shells, tracks | Fence with electric wire, secure trash |
| Blue Jay | Less than 0.2 lb per day | Small pecks on exposed nuts | Netting, decoy predators |
Other Pests That Eat Pecans

Squirrels: The Obvious Culprit
Not all damage comes from animals with fur or feathers. Insect pests can be just as destructive, and they're harder to spot. The pecan weevil is one of the worst. Female weevils puncture the nuts in late summer and lay eggs inside. The larvae then develop inside the pecan, eating the kernel from within. By the time you notice a problem, the nut is already ruined.
Here's how you can tell if weevils are the reason your pecans are being eaten: look for small, round holes in the shell — these are exit holes where adult weevils emerged. You might also see black spots or a soft, mushy texture on the outside of the nut. I've seen entire crops lost to weevils in a single season if left untreated. The best defense is to apply an insecticide specifically labeled for pecan weevils in late July or early August, depending on your region. You can also use sticky traps around the tree trunk to catch adult weevils before they lay eggs. Timing is everything — if you spray too early or too late, you'll waste your effort. Check with your local extension office for exact dates in your area.
Pecan Nut Casebearer and Hickory Shuckworm
Two other insect pests cause serious damage: the pecan nut casebearer and the hickory shuckworm. The casebearer's larvae feed on developing nuts in spring, causing them to drop prematurely. The shuckworm larvae tunnel into the shuck (the outer husk), cutting off the flow of nutrients and water to the nut inside.
You might ask: Why are my pecans falling off the tree before they're ripe? That's often a sign of casebearer or shuckworm damage. I've seen trees where half the young nuts dropped in May, and the owner had no idea insects were the cause. Inspect your tree weekly during spring and early summer. Look for small holes in the shucks or tiny caterpillars near the nut clusters. For casebearer, applying a Bacillus thuringiensis (Bt) spray at the right time can kill the larvae without harming beneficial insects. For shuckworm, you might need a targeted insecticide applied during the shuck-split stage. Don't wait until you see damage — by then, it's often too late to save the affected nuts.
Stinkbugs and Leaf-Footed Bugs
Other bugs use piercing and sucking mouthparts to feed on developing kernels. Brown and green stinkbugs, as well as leaf-footed bugs, are common culprits. They poke a hole in the pecan shell and suck out the juices, causing the kernel to shrivel and turn black or brown. The nut might look fine from the outside, but when you crack it open, you find a shriveled, discolored mess.
How do you know if these bugs are causing your pecans being eaten? Look for dark, sunken spots on the shell, or sticky residue (called honeydew) on the leaves and nuts. I've found that stinkbugs are especially active during hot, dry weather. They're hard to spot because they blend in with the bark and leaves. To manage them, keep the area around your tree free of weeds and debris where they hide. You can also use insecticidal soap or neem oil sprays, but you need to cover the entire tree thoroughly. Another tip: plant trap crops like sunflowers or millet nearby to attract the bugs away from your pecans. It's not a perfect solution, but it can reduce the damage significantly.
How to Identify the Signs of Pecan Damage
Photos provided by pixabay
Squirrels: The Obvious Culprit
You don't need to be a detective to figure out what's eating your pecans. Just look at the evidence left behind. If you see nuts on the ground with bite marks that look like tiny teeth, that's usually a rodent or squirrel. If the shells are still intact but the nuts are hollow, you're dealing with insects like weevils or stinkbugs.
Let me walk you through a quick checklist. Check the tree trunk for scratch marks — raccoons and squirrels leave claw marks when they climb. Look at the branches: broken twigs often mean a larger animal was scrambling around. Inspect the shucks: if they have small round holes, that's likely weevil damage. If they're split open but the nut is gone, birds are your culprit. Don't forget to look at the ground — tracks, droppings, and scattered shells tell a story. I always tell new gardeners to take photos each week. Over time, you'll spot patterns that make identification easy. Once you know the signs, you can act fast and save more of your harvest.
What Time of Day Matters
Pests don't work on a 9-to-5 schedule. Squirrels are active during the day, especially early morning and late afternoon. Raccoons are nocturnal, so damage that appears overnight is likely their doing. Birds feed at dawn and dusk. Insects are active during warm daylight hours.
Here's a practical tip: spend 10 minutes at different times of day watching your tree. I've caught squirrels red-handed at 6 AM and watched crows sweep in at sunset. If you see pecans being eaten overnight, set up a motion-activated camera or light to scare off nocturnal visitors. Knowing the timing helps you choose the right control method. For daytime pests, visual deterrents like reflective tape or scarecrows work. For nighttime pests, try motion-activated sprinklers or lights. Consistency is key — you need to keep up the pressure until the pests move on to easier food sources.
Prevention Strategies That Actually Work
Physical Barriers Are Your Best Friend
In my experience, physical barriers work better than any spray or repellent. Bird netting is cheap and effective if you install it before the nuts mature. Wrap it around the entire canopy and secure it at the trunk. For squirrels, a metal baffle on the trunk stops them from climbing up. I've seen homeowners reduce damage by 70-80% with just these two methods.
Let me give you a real-world example. A client in Oklahoma had lost almost all her pecan crop for three years straight. We installed a 4-foot-wide metal baffle on each tree trunk and covered the canopies with bird netting before the shucks split. That fall, she harvested over 50 pounds of pecans — the most she'd ever gotten. The initial cost was about $100 per tree, but she saved hundreds of dollars in lost nuts. Other physical barriers include fencing around the tree base to keep out raccoons and hogs, and using sticky bands on the trunk to catch crawling insects. Start early, and you'll thank yourself later.
Cultural Practices That Reduce Pest Pressure
Sometimes, the best prevention is good housekeeping. Rake up fallen nuts and debris regularly — they attract rodents, insects, and birds. Prune lower branches so animals can't reach the nuts from the ground. Keep the area around your tree clean and free of weeds where pests hide.
I can't stress this enough: a clean orchard is a healthy orchard. When you leave fallen pecans on the ground, you're basically inviting every squirrel, mouse, and insect in the neighborhood to a buffet. I recommend cleaning up at least once a week during harvest season. Compost the debris away from the tree or dispose of it in sealed bags. Also, consider planting companion plants that attract beneficial insects — they'll help control weevils and stinkbugs naturally. Good cultural practices don't cost much, but they save you a lot of frustration. Think of it as setting up a no-pest zone around your tree.
Common Myths About Pecan Pests
Myth: Only Squirrels Eat Pecans
This is one of the biggest myths I hear. People blame squirrels for everything, but the truth is that birds, raccoons, and insects cause just as much damage. If you focus only on squirrels, you might miss the real culprit. I've seen cases where 60% of the damage was from crows, but the homeowner was setting traps for squirrels and wondering why nothing changed.
You really need to look at all the evidence. Don't assume it's one pest. Check for signs of insects, look for bird droppings, and inspect the ground for tracks. Broad-spectrum prevention is usually more effective than targeting a single animal. For example, netting and baffles work against both squirrels and birds. Insecticides handle the bugs. A layered approach covers all your bases.
Myth: Pesticides Are the Only Solution
Many gardeners think they have to drench their tree in chemicals. That's not true at all. Physical barriers, cultural practices, and biological controls can be just as effective. Pesticides should be a last resort, not your first line of defense. Overusing chemicals can harm beneficial insects and even pollute your soil and water.
Here's my personal advice: try non-chemical methods first. Netting, baffles, and good sanitation will solve most pest problems. If you do need to use an insecticide, choose one that's specific to the pest you're dealing with and apply it at the right time. Always read the label and follow safety instructions. Your health and the environment matter more than a few extra pecans.
Seasonal Pest Calendar for Pecan Trees
Spring: Watch for Early Invaders
In spring, pecan nut casebearer larvae are active. They start feeding on young nuts in April or May, causing them to drop. This is also when stinkbugs emerge from overwintering sites. Inspect your tree weekly during this period.
What should you do? Apply a Bt spray if you see casebearer activity. Keep the area clean to discourage stinkbugs. Early detection is crucial because once the nuts are damaged, they won't recover. I always set a reminder on my phone for mid-April to do a thorough inspection. It takes just 15 minutes but can save you hours of frustration later.
Summer: The Peak Pest Season
Summer is when most damage happens. Pecan weevils lay eggs in July and August. Birds and squirrels are actively gathering nuts. Raccoons become bolder as the crop ripens. This is the time to have your barriers in place.
If you haven't installed netting or baffles by now, do it immediately. Check for weevil damage by looking for small holes. Apply insecticide if needed, but only after confirming the pest. Remember: prevention is always easier than cure. Spend the time now, and you'll enjoy a much better harvest in the fall. I've learned this the hard way — trust me, you don't want to wait until you see damage.
Final Thoughts on Protecting Your Pecan Harvest
You Can Save Your Pecans With the Right Approach
You don't have to let pests ruin your harvest. With a little effort and the right knowledge, you can protect your pecan tree and enjoy the fruits of your labor. Start by identifying the pest, then choose the appropriate prevention method. Remember: netting, baffles, and cleanliness are your best tools.
I've helped dozens of gardeners turn their trees from pest magnets into productive nut producers. The key is consistency. You can't just set up a baffle and forget about it — you need to monitor your tree, adjust your methods, and stay on top of the season. But it's totally worth it when you crack open a perfect pecan that you grew yourself. So don't give up. Use the tips in this guide, and you'll be well on your way to a successful harvest.
What to Do If You're Still Struggling
If you've tried everything and your pecans are still being eaten, don't hesitate to reach out for help. Your local agricultural extension office can provide specific advice for your region. They know what pests are common in your area and when to take action. Master gardeners and online forums are also great resources.
I always tell people: gardening is a learning process. You'll have good years and bad years. What matters is that you keep trying and learn from each season. Eventually, you'll find a system that works for your tree and your property. So take notes, stay patient, and enjoy the journey. Your perfect pecan harvest is waiting.

Summer is when most damage happens. Pecan weevils lay eggs in July and August. Birds and squirrels are actively gathering nuts. Raccoons become bolder as the crop ripens. This is the time to have your barriers in place.
If you haven't installed netting or baffles by now, do it immediately. Check for weevil damage by looking for small holes. Apply insecticide if needed, but only after confirming the pest. Remember: prevention is always easier than cure. Spend the time now, and you'll enjoy a much better harvest in the fall. I've learned this the hard way — trust me, you don't want to wait until you see damage.
Final Thoughts on Protecting Your Pecan Harvest
You Can Save Your Pecans With the Right Approach
You don't have to let pests ruin your harvest. With a little effort and the right knowledge, you can protect your pecan tree and enjoy the fruits of your labor. Start by identifying the pest, then choose the appropriate prevention method. Remember: netting, baffles, and cleanliness are your best tools.
I've helped dozens of gardeners turn their trees from pest magnets into productive nut producers. The key is consistency. You can't just set up a baffle and forget about it — you need to monitor your tree, adjust your methods, and stay on top of the season. But it's totally worth it when you crack open a perfect pecan that you grew yourself. So don't give up. Use the tips in this guide, and you'll be well on your way to a successful harvest.
What to Do If You're Still Struggling
If you've tried everything and your pecans are still being eaten, don't hesitate to reach out for help. Your local agricultural extension office can provide specific advice for your region. They know what pests are common in your area and when to take action. Master gardeners and online forums are also great resources.
I always tell people: gardening is a learning process. You'll have good years and bad years. What matters is that you keep trying and learn from each season. Eventually, you'll find a system that works for your tree and your property. So take notes, stay patient, and enjoy the journey. Your perfect pecan harvest is waiting.

FAQs
Q: Do squirrels really eat pecans, or is that just a myth?
A: No, that's not a myth at all — squirrels are one of the most common culprits when your pecans are being eaten. I've seen it happen time and again in backyard orchards. Squirrels don't wait for the nuts to ripen; they start harvesting as soon as the pecans begin to develop. One squirrel can easily damage or carry off about half a pound of pecans per day, and that adds up fast when you have a family of them nearby. The telltale signs include small bite marks on the shells, half-eaten nuts scattered on the ground, and scratch marks on the tree trunk. To stop them, I recommend installing a metal baffle on the trunk at least six feet off the ground — this prevents them from climbing up. You can also trim overhanging branches that give them a jumping-off point. Trust me, I've helped gardeners in Georgia cut their squirrel damage by over 70% with just these simple steps. Don't assume it's only squirrels, though — always check for other pests too.
Q: Is it true that pesticides are the only way to stop bugs from eating pecans?
A: That's a common misconception, and I'm glad you asked. While pesticides can be effective, they're far from the only solution — and they shouldn't be your first line of defense. In my experience, physical barriers and good cultural practices work just as well, if not better. For example, installing bird netting before the nuts mature can stop crows and blue jays from stealing your crop, and a metal baffle on the trunk keeps squirrels at bay. For insects like pecan weevils or stinkbugs, you can use sticky traps around the trunk or apply targeted sprays like Bacillus thuringiensis (Bt) for casebearer larvae — these are much safer than broad-spectrum chemicals. I always tell gardeners to start with non-chemical methods: rake up fallen nuts weekly, keep the area clean, and prune low branches so pests can't reach. Overusing pesticides can harm beneficial insects like bees and ladybugs, and it might even pollute your soil. So, no, you don't need to drench your tree in chemicals. A layered approach — netting, baffles, sanitation, and spot treatments — is usually enough to protect your harvest. I've seen homeowners in Texas save 80% of their crop using just netting and a clean yard.
Q: How can I tell if birds or insects are the ones eating my pecans?
A: Great question — and the answer lies in the clues you find on and around the tree. Let me break it down for you based on what I've seen in dozens of gardens. If birds are the culprits, you'll notice the nuts disappearing right after the shucks split open in late summer or early fall. Crows, for instance, can eat up to one pound of pecans per day, and they often leave empty shells on the ground or in the branches. You might also see bird droppings or feathers near the tree. Insects, on the other hand, leave more subtle signs. Pecan weevils create small, round exit holes in the shells — look for these on fallen nuts. Stinkbugs and leaf-footed bugs cause dark, sunken spots on the shell, and when you crack the nut open, the kernel is shriveled and discolored. Hickory shuckworm larvae tunnel into the shuck, causing it to stick to the nut. I always tell gardeners to do a weekly inspection during spring and summer: check for holes, sticky residue called honeydew, or tiny caterpillars near the nut clusters. Take photos each week to spot patterns. Once you know the signs, you can act fast — whether that means putting up bird netting or applying a targeted insecticide. Don't guess; let the evidence guide you.
Q: What do I do if my pecans are being eaten by raccoons or possums?
A: If raccoons or possums are raiding your tree, you need a different strategy than for squirrels or birds. I've dealt with this myself and helped several homeowners in rural areas. Raccoons are nocturnal and very crafty — they can climb trees, open simple latches, and even work together to knock nuts to the ground. Possums are less destructive but will still eat fallen pecans. The key signs are broken branches, scattered shells, and tracks or droppings around the tree base. The best prevention is a sturdy fence around the tree, ideally with an electric wire at the top to deter climbers. For a single tree, you can also wrap the trunk with a smooth metal sheet or a cone-shaped baffle that raccoons can't grip. I recommend installing these before the nuts start to ripen in late summer. Keep the area clean of fallen nuts — raccoons are attracted to easy food sources. You can also use motion-activated lights or sprinklers to scare them off at night. I've seen these methods reduce damage by 50-60% in just a few weeks. Remember, trapping or relocating raccoons is often illegal or ineffective, so focus on exclusion instead. Start early, and you'll save yourself a lot of frustration.
Q: What's the best overall strategy to prevent my pecans from being eaten?
A: The best strategy combines physical barriers, good sanitation, and timely monitoring — and I've seen it work wonders for home gardeners. Start by installing a metal baffle on the tree trunk about six feet off the ground to stop squirrels and raccoons from climbing. Cover the entire canopy with bird netting before the shucks split, usually in late July or early August, to keep crows and blue jays out. Next, keep the area clean: rake up fallen nuts and debris weekly during harvest season, and compost them away from the tree — this removes food sources for insects and rodents. Prune low branches so animals can't reach the nuts from the ground. For insects, inspect your tree weekly from spring through summer. Look for small holes, sticky residue, or premature nut drop. If you spot pecan weevil damage, apply a targeted insecticide in late July or August — check with your local extension office for exact timing. I also recommend planting companion plants like sunflowers or millet nearby to attract stinkbugs away from your pecans. This layered approach — barriers, cleanliness, and spot treatments — can reduce your losses by 70-80% in my experience. It takes some effort upfront, but it's totally worth it when you harvest a full crop of perfect pecans.
