What Is Eating Large Holes in My Tomatoes

When you look forward to a ripe, sun-warmed tomato only to find it marred by unsightly, large holes, the disappointment can be great indeed. Something is feasting on your garden’s rewards and you’re left wondering, “what is eating large holes in my tomatoes?”

The culprits could be many, ranging from airborne pests to crawly critters. Figuring out who the offenders are is the first step in combating this issue and preserving your luscious tomato harvest.

What Is Eating Large Holes in My Tomatoes?

The most common pests that eat large holes in tomatoes are tomato hornworms, beetles, slugs, and rodents. Tomato hornworms are especially notorious for causing significant damage to tomatoes. Other possibilities could be larger creatures like birds or squirrels. It’s essential to identify the exact culprit for effective treatment.

– Ants

Description Insect with strong jaws, causing extensive damage to tomato plants by creating large holes.
Damage Damages: Leaf discoloration, stunted growth, weakened plant structure.
Control Use natural pest control methods like diatomaceous earth or sticky traps, remove affected leaves, and create physical barriers.

The holes in your tomatoes are likely being caused by ants. **Ants** can damage your tomatoes by their feeding activities which involve boring numerous small holes into the fruit. Once the skin is punctured, the fruit is exposed and becomes susceptible to secondary pests and diseases.

Solutions to the infestation involve multiple steps. It’s crucial to practice proactive gardening to prevent an ant invasion. Improving the general hygiene of the garden such as removing dead or diseased plants promptly can help reduce ant habitats. Using traps and baits with slow-acting pesticides can effectively control the ant population over time. Natural methods, like using beneficial insects such as ladybugs that prey on ants, can be employed as well. It’s also advisable to keep the garden mulched to conserve moisture, reduce weeds, and deter ants.

However, ants can sometimes facilitate the activities of aphids, mealybugs, and other pests, as they ‘farm’ these insects for the sweet secretions they produce. Hence, you should also look out for these pests in your garden and manage them accordingly.

Physical barriers could also be established to prevent ants from reaching your tomatoes. Tanglefoot Pest Barrier is a sticky substance that could be applied to stakes supporting your tomato plants. The ants become stuck in the substance and are prevented from reaching the fruits. Finally, if these methods do not curb the infestation, consider consulting with a pest control professional.

– Flies

Description Small black flies with transparent wings, laying eggs on tomato leaves and causing large holes in the foliage.
Damage Significant loss of foliage and fruit leading to reduced yield and plant health.
Control Implement physical barriers, such as netting or row covers, to prevent flies from accessing the tomato plants.

The culprit could be tomato hornworms or other types of caterpillars. These pests are known for their voracious appetites and can cause severe damage to your tomato plants. They usually start feeding from the top part of the plant, eating the leaves, stems, and fruits, leaving large, irregular holes in the tomatoes.

Prevention and Treatment: To control these pests, regular inspection of your plants is vital. Look for signs of their presence such as droppings and stripped foliage. Handpicking is an effective control method if the infestation is minor. If the problem persists, consider using a natural insecticide such as Bacillus thuringiensis (Bt). This is a bacterium that is harmful to caterpillars but safe for humans, animals, and beneficial insects.

For further prevention, you may also introduce natural predators like ladybugs and predatory wasps into your garden, which can naturally control the caterpillar population. Lastly, practicing crop rotation and proper garden sanitation can keep these pests’ population down.

Damage Leaves damaged and large holes in tomatoes.
Control Implement physical barriers such as fine mesh netting or row covers to protect tomato plants from pest damage.

There may be several reasons for large holes in your tomatoes, but the most common culprits are tomato hornworms, slugs, or birds.

Tomato hornworms are large, green caterpillars that can devour enormous amounts of foliage and fruits.

Slugs and snails are commonly known for their voracious appetites and will leave large, jagged holes in the vegetables, especially after a rainfall or during the night.

Birds can also cause damage, pecking at the ripe fruits to eat the seeds inside. They usually leave larger, more rounded holes compared to other pests.

To control tomato hornworms, a hand-picking method is often effective. Check your plants regularly, especially in the morning or late evening, and remove any you see. For long-term control, use beneficial insects like parasitic wasps or introduce Bacillus thuringiensis, a natural bacteria that serves as a biological pesticide.

For slugs, try to decrease moisture around your plants as slugs are attracted to damp conditions. You can also use beer traps, copper barriers, or commercial slug pellets to manage these pests.

Finally, in the case of birds, you can discourage them by using netting to cover your plants, or use visual deterrents such as shiny objects or garden spinners that move with the wind. Encouraging predatory birds, like owls and hawks, can help as well.

– Cockroaches

Description Small, nocturnal insects with flattened bodies, long antennae, and chewing mouthparts, causing extensive damage to tomato plants by creating large holes.
Damage Severe destruction to tomato plants caused by voracious feeding.
Control Use organic insecticide, remove infected leaves, place sticky traps, and encourage natural predators like birds and ladybugs.

Harm Caused: Cockroaches are omnivorous and can feast on your tomatoes, especially in the night or early morning hours. They bite large holes into the fruits leaving them damaged and unappealing. It can significantly reduce your harvest and is harmful as the roaches may also spread diseases to the plants thus affecting their health.

Solutions: Utilize cockroach traps, baits, or insecticidal sprays to control the roach population. Clean the garden area frequently to remove potential hiding spots and food sources. It is also beneficial to attract natural enemies of cockroaches, such as birds and toads, into your garden. For severe infestations, professionals may need to be contacted.
