Chipmunks eat a wide variety of plants, including flowers, vegetables, and young seedlings. If you’ve noticed small bite marks or missing plants in your garden, you might be asking yourself: do chipmunks eat plants? The short answer is yes, they do. These small, striped rodents are opportunistic feeders, and your garden can be a prime target for them.
Understanding what chipmunks eat and how they behave is key to protecting your plants. This article will cover everything you need to know about chipmunks and their plant-eating habits, plus practical ways to manage them.
Do Chipmunks Eat Plants
Chipmunks are not picky eaters. They are omnivores, meaning they eat both plants and small animals. However, plants make up a large part of their diet, especially during spring and summer. They are known to eat seeds, nuts, fruits, and green vegetation. But when it comes to your garden, they often target tender young plants and bulbs.
They are especially drawn to newly sprouted seedlings. If you’ve just planted seeds or transplants, chipmunks may dig them up or nibble the stems. They also enjoy flower buds, ripe fruits, and even some vegetables like tomatoes and strawberries.
What Plants Do Chipmunks Prefer
Chipmunks have clear favorites. They tend to go for soft, moist plants over tough or woody ones. Here are some common plants they eat:
- Flowers: Tulips, crocuses, and other spring bulbs are often dug up and eaten. They also like pansies and petunias.
- Vegetables: Tomatoes, cucumbers, peppers, and leafy greens like lettuce and spinach are popular.
- Fruits: Strawberries, blueberries, and raspberries are easy targets. They may also eat fallen apples or peaches.
- Seedlings: Young sprouts of almost any plant are vulnerable, including sunflowers and beans.
They also eat seeds from bird feeders, which can bring them close to your garden. If you have a bird feeder, you might notice chipmunks gathering underneath it.
How Chipmunks Damage Plants
Chipmunks don’t just eat plants; they can also damage them in other ways. They dig burrows near plant roots, which can disturb the soil and harm the plant. They may also eat bulbs whole, leaving empty holes in your garden.
Another common issue is that they clip stems and leaves. This can stunt growth or kill young plants. They are also known to eat fruit before it’s fully ripe, ruining your harvest.
Signs of Chipmunk Activity
If you suspect chipmunks are eating your plants, look for these signs:
- Small, shallow holes in the soil near plants or bulbs.
- Missing or partially eaten fruits and vegetables.
- Chewed stems or leaves, often at ground level.
- Small droppings that look like dark rice grains.
- Burrow entrances near garden beds or under rocks.
These signs can help you confirm whether chipmunks are the culprit, rather than other pests like squirrels or rabbits.
Why Chipmunks Eat Plants
Chipmunks eat plants for several reasons. First, they need energy to survive. Plants provide carbohydrates, vitamins, and moisture. During spring and summer, they are actively gathering food to store for winter. They have cheek pouches that allow them to carry large amounts of seeds and bulbs back to their burrows.
Second, chipmunks are territorial. They often eat plants that are close to their burrows. If your garden is near a rock wall, woodpile, or dense shrubbery, it’s more likely to be visited.
Third, they are curious and will sample new plants. This means that even if you plant something they don’t normally eat, they might still take a bite out of curiosity.
Seasonal Eating Habits
Chipmunks change their diet with the seasons. In early spring, they eat fresh green shoots and bulbs. As summer progresses, they switch to fruits and seeds. In fall, they focus on gathering nuts and seeds for winter storage.
During winter, chipmunks hibernate but wake up occasionally to eat from their stored food. This stored food often includes plant parts like seeds and bulbs. So even if you don’t see them in winter, they may have already taken from your garden.
How To Protect Your Plants From Chipmunks
If you want to keep chipmunks from eating your plants, there are several methods you can try. Some are simple, while others require more effort. Here are the most effective strategies:
Physical Barriers
Barriers are one of the best ways to stop chipmunks. You can use:
- Wire mesh or hardware cloth: Place it over soil or around bulbs. Make sure the holes are small enough that chipmunks can’t squeeze through.
- Row covers: Lightweight fabric that lets sunlight and water through but keeps animals out.
- Fencing: A fence that is buried at least 6 inches deep and stands 2 feet tall can help. Chipmunks are good climbers, so a smooth surface like plastic or metal is best.
You can also use netting over fruit bushes or vegetable beds. Just be sure to secure it tightly so chipmunks can’t get underneath.
Repellents
There are many repellents on the market, but their effectiveness varies. Some common ones include:
- Predator urine: Fox or coyote urine can scare chipmunks, but it needs to be reapplied after rain.
- Hot pepper spray: Mix cayenne pepper with water and dish soap. Spray it on plants, but avoid getting it on edible parts.
- Garlic or onion sprays: Strong smells can deter chipmunks, but they may not work for long.
Natural repellents like these are safer for pets and children, but they often need frequent reapplication.
Habitat Modification
Changing your garden environment can make it less attractive to chipmunks. Here are some tips:
- Remove rock piles, woodpiles, and dense brush where chipmunks can hide.
- Keep grass short and trim bushes to reduce cover.
- Seal gaps in foundations, walls, and under decks to prevent burrowing.
If you have bird feeders, place them away from your garden. Use trays to catch fallen seeds, or switch to seeds that chipmunks don’t like, such as safflower seeds.
Trapping And Relocation
Trapping is a more direct method, but it should be done carefully. Check local laws before trapping, as some areas have restrictions. Use live traps baited with peanut butter, sunflower seeds, or fruit. Place the trap near burrows or along their travel routes.
Once caught, relocate the chipmunk at least 5 miles away in a suitable habitat. Wear gloves when handling the trap to avoid disease. This method can be time-consuming, but it works well for small infestations.
Natural Predators
Encouraging natural predators can help control chipmunk populations. Owls, hawks, snakes, and foxes all eat chipmunks. You can attract them by:
- Installing owl boxes or perches for hawks.
- Leaving some areas of your garden wild for snakes.
- Avoiding pesticides that harm predators.
Keep in mind that predators may also eat other animals you want to protect, so weigh the pros and cons.
Common Misconceptions About Chipmunks And Plants
There are many myths about chipmunks and their eating habits. Let’s clear up a few:
- Myth: Chipmunks only eat nuts and seeds. Fact: They eat a wide range of plants, including flowers and vegetables.
- Myth: Chipmunks are the same as squirrels. Fact: While related, chipmunks are smaller, have stripes on their face, and are more ground-dwelling.
- Myth: Chipmunks don’t eat mature plants. Fact: They will eat mature fruits and vegetables, especially if they are soft and easy to reach.
Understanding these facts can help you better identify and address chipmunk damage in your garden.
When To Call A Professional
If chipmunks are causing significant damage and home methods aren’t working, it may be time to call a wildlife control professional. They can assess the situation, use humane trapping methods, and help seal entry points. This is especially important if chipmunks are burrowing near your home’s foundation, which can cause structural issues.
Professionals can also advise on long-term prevention. They may recommend habitat changes or exclusion techniques that you might not have considered.
