How to Keep Caterpillars Off Your Tomato Plants

Caterpillars can be a major nuisance in the garden, especially when they start munching on your beloved tomato plants. Here are some tips on how to keep those pesky caterpillars away:

1. Handpicking

The most effective way to keep caterpillars off your tomato plants is to physically remove them by hand. Head out to your garden in the morning or evening when the caterpillars are most active and begin searching your plants for any signs of them. Pick them off one by one and dispose of them somewhere far away from your garden to prevent them from coming back.

2. Natural Predators

Encourage natural predators like birds, wasps, and spiders to come to your garden by planting flowers and shrubs. These predators are beneficial because they feed on insects and caterpillars that could harm your plants. Additionally, you can purchase beneficial insects like ladybugs or praying mantises to release into your garden as a natural pest control.

3. Neem Oil

Neem oil is a natural insecticide that can be sprayed on your tomato plants to keep caterpillars away. Simply mix a few tablespoons of neem oil with water and spray it onto your plants. The oil works by disrupting the digestive systems of insects, causing them to stop eating and eventually die off.

4. Bacillus Thuringiensis

Bacillus thuringiensis, or Bt for short, is a bacterium that is safe for humans but deadly to caterpillars. This bacterium can be purchased as a spray or powder and applied directly to your tomato plants. Once the caterpillars eat the treated leaves, they will stop feeding and eventually die off.

5. Companion Planting

Companion planting is an effective way to naturally repel caterpillars and other pests from your tomato plants. Interplanting herbs like basil or mint, or vegetables like onions or garlic, can help to deter caterpillars and other insects from your garden. Additionally, planting marigolds or nasturtiums around your tomato plants can also help to keep pests away.

6. Row Covers

Using row covers is another effective method of keeping caterpillars away from your tomato plants. Simply cover your plants with a lightweight fabric like cheesecloth or row cover material, and secure it in place with stakes. This will prevent the caterpillars from accessing your plants and causing damage.

By using these methods, you can keep caterpillars off your tomato plants and ensure that your harvest is healthy and plentiful. Remember to inspect your plants regularly and treat any signs of infestation promptly to prevent the problem from getting out of control.
