Tomatoes, with their juicy sweetness and vibrant color, are a staple in gardens and kitchens worldwide. But humans aren’t the only ones who find these fruits appealing. A wide variety of animals, from tiny insects to larger mammals, enjoy snacking on fresh tomatoes, much to the dismay of many gardeners. Understanding which animals are likely to target your tomato plants and the damage they can inflict is crucial for protecting your harvest.
Identifying Tomato-Loving Animals
Knowing your enemy is the first step in defending your tomato plants. Different animals leave different signs of their presence and feeding habits. Identifying the culprit allows you to implement targeted control measures.
Insects: Tiny Tomato Thieves
Many insect species are drawn to the lush foliage and ripe fruit of tomato plants. Their small size often allows them to go unnoticed until significant damage has already occurred.
Tomato Hornworms: These large, green caterpillars are notorious for their voracious appetites. They can quickly defoliate entire tomato plants, leaving behind only bare stems. Look for their distinctive horn on their rear end and black droppings on the leaves.
Aphids: These tiny, sap-sucking insects cluster on stems and undersides of leaves, weakening the plant and causing distorted growth. They also secrete a sticky substance called honeydew, which can attract ants and promote the growth of sooty mold.
Whiteflies: Similar to aphids, whiteflies suck sap from tomato plants, causing yellowing and wilting. They are small, white, and fly up in a cloud when disturbed.
Flea Beetles: These tiny, jumping beetles create small, round holes in tomato leaves, giving them a shot-hole appearance. While their damage is usually minor, heavy infestations can weaken young plants.
Spider Mites: These tiny arachnids are difficult to see with the naked eye, but their presence is revealed by fine webbing on the undersides of leaves. They suck sap, causing leaves to become stippled and eventually turn brown.
Birds: A Peckish Problem
Birds, attracted to the bright red color and juicy flesh of ripe tomatoes, can cause significant damage to your harvest. They often peck at the fruit, leaving unsightly holes and making them susceptible to rot.
Robins: These common garden birds are known for their love of tomatoes. They often peck at ripe fruit, especially when they are seeking moisture during dry periods.
Starlings: Starlings are opportunistic feeders and will readily consume tomatoes if they are available. They tend to feed in flocks, causing widespread damage.
Mockingbirds: Mockingbirds are territorial birds that may peck at tomatoes to defend their territory or simply out of curiosity.
Mammals: Larger Tomato Predators
Larger mammals can inflict more extensive damage to tomato plants and fruits. Their feeding habits can range from nibbling on leaves to consuming entire fruits.
Squirrels: These nimble rodents are notorious for raiding gardens. They are attracted to the sweetness of ripe tomatoes and can quickly decimate a harvest. They often take a few bites out of multiple tomatoes rather than consuming one completely.
Rats and Mice: These rodents are opportunistic feeders and will readily consume tomatoes if they are available. They can also damage tomato plants by gnawing on stems and roots.
Raccoons: These nocturnal animals are highly intelligent and adaptable. They are attracted to the sweetness of ripe tomatoes and can wreak havoc in gardens, often knocking over plants and scattering fruit.
Deer: Deer are herbivores that can consume entire tomato plants, including leaves, stems, and fruits. Their browsing habits can quickly devastate a garden.
Groundhogs (Woodchucks): These large rodents are voracious eaters and can consume large quantities of tomatoes and other garden vegetables. They often dig burrows near gardens, making them a persistent problem.
Chipmunks: Similar to squirrels, chipmunks are attracted to the sweetness of ripe tomatoes and may nibble on them, causing damage.
Identifying Damage and Diagnosing the Culprit
Pinpointing the animal responsible for damaging your tomato plants is crucial for implementing effective control measures. Observing the type of damage, the time of day it occurs, and any signs of animal presence can provide valuable clues.
Holes in Leaves: Small, round holes typically indicate flea beetles. Larger, irregular holes suggest caterpillars, such as tomato hornworms.
Stippled Leaves with Webbing: This is a telltale sign of spider mites.
Yellowing and Wilting Leaves: Aphids and whiteflies can cause these symptoms by sucking sap from the plant.
Peck Marks on Fruit: Birds are the likely culprits.
Bite Marks on Fruit: Squirrels, rats, mice, and chipmunks may leave bite marks on tomatoes.
Missing Fruit: Raccoons, opossums, and deer may consume entire tomatoes, leaving little or no evidence behind.
Plants Uprooted or Knocked Over: Larger animals, such as raccoons and deer, can cause this type of damage.
Protecting Your Tomato Plants: Effective Strategies
Once you have identified the animals that are targeting your tomato plants, you can implement targeted control measures to protect your harvest. A combination of strategies is often the most effective approach.
Physical Barriers: Keeping Animals Out
Physical barriers are an effective way to prevent animals from accessing your tomato plants.
Fencing: Surrounding your garden with a fence can deter larger animals, such as deer, rabbits, and groundhogs. The fence should be at least 6 feet tall to deter deer and buried at least 1 foot deep to prevent animals from digging underneath.
Netting: Covering your tomato plants with netting can protect them from birds, squirrels, and other small animals. Choose a netting with small holes to prevent animals from getting tangled.
Row Covers: These lightweight fabrics can be used to cover tomato plants, protecting them from insects and other pests.

Companion planting involves planting certain plants near your tomato plants to repel pests or attract beneficial insects.
Marigolds: These flowers are known to repel nematodes and other pests.
Basil: Basil is a fragrant herb that can repel tomato hornworms and other insects.
Garlic: Garlic can repel aphids and other pests.
Beneficial Insects: Natural Predators
Attracting beneficial insects to your garden can help control pests that target tomato plants.
Ladybugs: Ladybugs are voracious predators of aphids.
Lacewings: Lacewings are also predators of aphids and other soft-bodied insects.
Parasitic Wasps: These tiny wasps lay their eggs inside pests, eventually killing them.
Other Strategies
Harvesting Early: Harvesting tomatoes as soon as they begin to ripen can reduce the risk of animal damage.
Cleaning Up Debris: Removing fallen leaves and other debris from your garden can reduce hiding places for pests and rodents.
Trapping: Trapping can be an effective way to control rodents and other small animals.
Specific Animal Control Measures
Each type of animal requires a slightly different approach to control. Understanding the specific habits and preferences of each animal will help you tailor your control measures for maximum effectiveness.
Controlling Insects
Handpicking: For large pests like tomato hornworms, handpicking them off the plants and destroying them is an effective method.
Insecticidal Soap: Insecticidal soap can be used to control aphids, whiteflies, and other soft-bodied insects.
Neem Oil: Neem oil is a natural insecticide that can control a variety of pests.
Bacillus thuringiensis (Bt): Bt is a bacterium that is toxic to caterpillars.
Controlling Birds
Netting: Covering tomato plants with netting is an effective way to prevent birds from accessing the fruit.
Bird Scare Devices: Reflective tape, scarecrows, and other bird scare devices can help deter birds from your garden.
Providing Water: Providing a source of water for birds away from your tomato plants may reduce their need to peck at the fruit for moisture.
Controlling Mammals
Fencing: A sturdy fence is essential for deterring larger mammals like deer and groundhogs.
Trapping: Live traps can be used to capture and relocate rodents and other small animals. Check local regulations regarding trapping and relocation.
Repellents: Commercial or homemade repellents can deter mammals from approaching your garden.
Guard Animals: Dogs or cats can deter some mammals from entering your garden.

Practice humane and ethical control methods, and avoid using harmful pesticides or traps that could harm non-target animals.
Growing tomatoes can be a rewarding experience, but it also requires vigilance and proactive measures to protect your plants from hungry animals. By understanding which animals are likely to target your tomatoes, identifying the damage they cause, and implementing effective control strategies, you can enjoy a bountiful harvest and coexist peacefully with wildlife. Remember, patience and persistence are key to success in the garden.
What garden pests are most likely to eat my fresh tomatoes?
Several common garden pests are notorious for enjoying fresh tomatoes. These include various types of insects like tomato hornworms, aphids, whiteflies, and fruit flies. Additionally, larger pests such as squirrels, rabbits, and even birds can also cause significant damage by feeding on ripening tomatoes.
The damage caused by these pests can vary significantly. Insects often leave small holes or blemishes, whereas larger animals may take large bites or completely consume entire tomatoes. Understanding which pests are most prevalent in your area is crucial for implementing effective control measures.
Are there any animals that eat green, unripe tomatoes?
While ripe, red tomatoes are a favorite target, some animals will indeed consume green, unripe tomatoes. Slugs and snails are known to nibble on green tomatoes, leaving irregular trails of damage. Certain bird species, especially if thirsty or lacking other food sources, may also peck at green tomatoes.
The toughness and acidity of unripe tomatoes typically make them less appealing than their ripe counterparts. However, pests that are less picky or have limited food options will often resort to eating them. Protective measures are still necessary even before the tomatoes fully ripen.
How can I tell if squirrels are eating my tomatoes?
Squirrels are notorious for taking clean, almost surgically precise bites out of tomatoes, often leaving a half-eaten fruit still on the vine. They tend to target ripe or nearly ripe tomatoes, and the damage is often easily distinguishable from the irregular, messy holes left by insects or birds. You might also find tomato pieces scattered around the garden.
Another telltale sign is the presence of squirrel droppings nearby. Squirrels are also known to be active during the day, so you might even catch them in the act. Look for damage near the top of the plant, as squirrels can easily climb to reach higher fruits.
What can I do to protect my tomatoes from birds?
Protecting tomatoes from birds requires a multi-pronged approach. Covering your tomato plants with netting is a highly effective physical barrier. The netting should be fine enough to prevent birds from reaching the fruit but allow sunlight and air circulation. Another effective method is to use visual deterrents.
Shiny objects like aluminum pie plates or reflective tape can startle birds and discourage them from approaching your plants. Motion-activated sprinklers can also scare birds away. Remember to move deterrents regularly so birds don’t get used to them.
Are deer likely to eat tomato plants and their fruit?
Deer are opportunistic feeders and, unfortunately, they will readily consume tomato plants, including both the foliage and the fruit. They are attracted to the lush green growth of the plants and the sweet taste of the ripe tomatoes. Deer can cause significant damage overnight, often stripping entire plants bare.
To protect your tomato plants from deer, consider installing a tall fence around your garden. The fence should be at least 6-8 feet high to prevent deer from jumping over it. Deer repellents, available in both liquid and granular forms, can also be effective in deterring them.
What about slugs and snails? How can I prevent them from damaging my tomato plants?
Slugs and snails are common garden pests that can cause considerable damage to tomato plants, particularly the fruit closest to the ground. They typically leave irregular, shallow holes in the tomatoes, often accompanied by silvery slime trails. These pests are most active at night or during damp, overcast weather.
To control slugs and snails, try using physical barriers such as copper tape around your raised beds or individual plants. Beer traps, where slugs and snails are attracted to beer and drown, are also effective. Organic slug pellets containing iron phosphate are a safer alternative to traditional slug pellets that contain metaldehyde.
What natural predators can help control pests that eat tomatoes?
Encouraging natural predators into your garden is an excellent way to control pests that eat tomatoes. Ladybugs are voracious consumers of aphids, a common tomato pest. Lacewings also feed on aphids, as well as other small insects like whiteflies and spider mites.
Attracting birds to your garden can also help control insect populations. Birds will feed on caterpillars, including tomato hornworms, and other insects that damage tomato plants. Planting flowers that attract beneficial insects, providing a water source, and avoiding the use of broad-spectrum pesticides will help create a balanced ecosystem in your garden.
