If you’ve ever found neat little bites taken out of your ripe tomatoes, you might be wondering: do chipmunks eat tomatoes? The answer, unfortunately for gardeners, is a definite yes. These garden-loving little creatures are often the culprits behind those frustrating nibbles. While they’re charming to watch, their appetite for your hard-grown produce can test any gardener’s patience.
This article will help you understand why chipmunks target your tomato plants and, more importantly, how to protect your harvest using effective, humane methods.
Do Chipmunks Eat Tomatoes
Chipmunks are opportunistic omnivores. This means they eat a wide variety of foods, from seeds and nuts to insects and, yes, fruits and vegetables. A ripe tomato, with its high water content and sweet flesh, is a tempting source of food and hydration, especially in the heat of summer. They are most likely to go for fruits that are low-hanging or that have fallen to the ground.
Why Your Garden is a Chipmunk Buffet
Your vegetable plot provides everything a chipmunk needs. Understanding their motivations is the first step to managing them.
* Food Source: Tomatoes are an easy, nutritious meal. Chipmunks will also eat strawberries, peas, and even bulbs.
* Water Source: The juicy interior of a tomato provides vital hydration.
* Shelter: Dense foliage, woodpiles, and garden debris offer perfect cover from predators.
* Territory: Gardens often border their natural woodland or rock wall habitats, making your yard a simple extension of their foraging grounds.
Signs Chipmunks Are Visiting Your Tomatoes
Before you blame every garden pest on chipmunks, it’s good to confirm they’re the visitors. Here’s what to look for:
* Clean, small bites: Chipmunks leave behind distinct, curved nibble marks about the size of a pea.
* Partially eaten fruit: They often eat just part of a tomato, leaving the rest to rot on the vine or ground.
* Tiny footprints: Look for small, five-toed paw prints in soft soil.
* Burrows: Check for small, clean holes (about 2 inches in diameter) near garden borders, under sheds, or in rock walls.
Humane Strategies to Protect Your Tomato Plants
The goal is to deter, not harm, these native creatures. A combination of methods usually works best.
1. Create Physical Barriers
This is the most reliable way to keep chipmunks away from your plants.
* Use Hardware Cloth: Create cages or cylinders around individual plants using 1/4-inch mesh hardware cloth. Bury the edges at least 6 inches deep to prevent digging.
* Install Fencing: Surround your garden with a fine-mesh fence that is at least 18 inches tall and buried 6-8 inches underground. Bend the top outward to make it harder to climb.
* Protect Containers: For potted tomatoes, consider placing the pots on a smooth stand or wrapping the base with a slick material they can’t climb.
2. Make Your Garden Less Appealing
Remove the things that attract chipmunks in the first place.
* Clean Up Fallen Fruit: Pick up any damaged or overripe tomatoes immediately. Don’t give them an easy meal on the ground.
* Reduce Cover: Keep grass trimmed, move woodpiles away from the garden, and clear out thick ground cover where they might hide.
* Use Container Plants: Raising tomatoes in pots on a deck or patio can put them out of easy reach.
3. Try Natural Deterrents
Some smells and tastes can persuade chipmunks to dine elsewhere.
* Sprinkle Cayenne Pepper: Dusting plants and the surrounding soil with cayenne or a commercial hot pepper spray can deter nibbling. Reapply after rain.
* Plant Deterrents: Some gardeners have success with planting strong-smelling herbs like garlic, onions, or mint around the garden’s perimeter.
* Use Predator Scents: Granules or sprays containing fox or coyote urine, available at garden centers, can create a sense of danger. Their effectiveness can vary.
4. Employ Safe Trapping and Relocation
If you have a persistent problem, live-trapping may be an option. Always check your local wildlife regulations first, as relocating wildlife is illegal in some areas.
1. Buy a small, humane live trap.
2. Bait it with sunflower seeds or peanut butter.
3. Place the trap near the chipmunk’s burrow or along their travel path.
4. Check the trap frequently, at least twice a day.
5. Relocate the chipmunk to a suitable, wooded area far from your home (if permitted by law).
What Not to Do: Ineffective or Harmful Methods
Some common advice simply doesn’t work or causes more problems.
* Ultrasonic Devices: There is little evidence these work for chipmunks, and they can disturb pets.
* Mothballs: These are toxic to soil, pets, and children, and are not a registered pesticide for this use.
* Poison: This is inhumane and poses a severe risk to pets, birds of prey, and other wildlife that might eat a poisoned chipmunk.
Balancing a love for gardening with the presence of local wildlife is part of the gardening journey. With persistence and the right tactics, you can enjoy a bountiful tomato harvest while letting chipmunks play their role in the ecosystem—just somewhere else.
FAQ: Chipmunks and Garden Troubles
Q: Do chipmunks eat green tomatoes as well as red ones?
A: They typically prefer ripe, red tomatoes for their sweetness and softness. However, a hungry chipmunk might sample a green tomato, especially if other food is scarce.
Q: What other vegetables do chipmunks commonly eat?
A: Besides tomatoes, chipmunks are known to eat corn, berries, squash, cucumbers, and leafy greens. They also dig up and eat flower bulbs like tulips and crocus.
Q: Are there any plants that chipmunks avoid?
A: Chipmunks tend to steer clear of plants with strong smells or bitter tastes. This includes daffodils (which are toxic), alliums like garlic and onions, and some herbs like mint and lavender. Planting these around the border might help.
Q: Will a cat or dog keep chipmunks out of the garden?
A: The presence of a pet can deter chipmunks, as they recognize predators. However, a determined chipmunk will often just become more sneaky, foraging when the pet is indoors. It’s not a guaranteed solution.
Q: How can I tell if it’s a chipmunk or a bird eating my tomatoes?
A: Birds usually peck at tomatoes, creating irregular holes. Chipmunks leave cleaner, sharper bite marks. Also, birds rarely take bites out of low-hanging fruit, while chipmunks will.
