What Gets Rid of Flea Beetles on Tomato Plants

Flea beetles are a common pest that can cause significant damage to tomato plants. These small, black or brown insects chew tiny holes in the leaves and can quickly ruin a crop. Fortunately, there are several ways to get rid of flea beetles on tomato plants without resorting to harmful chemicals. Here are some effective methods to consider:

1. Use Beneficial Insects

One of the most effective ways to control flea beetles on tomato plants is to introduce beneficial insects that prey on them. Two popular options are ladybugs and lacewings. These insects feed on flea beetles and will help keep their numbers under control. You can purchase them from garden centers or online retailers and release them in your garden when the flea beetles become a problem.

2. Install Physical Barriers

Flea beetles can be deterred by physical barriers that prevent them from reaching the tomato plants. One option is to install row covers made of lightweight fabric over the plants. This barrier will prevent the flea beetles from landing on the plants and will also protect them from other pests. Another option is to surround the tomato plants with sticky traps, which will trap the beetles when they land on them.

3. Crop Rotation

Crop rotation can be an effective way to prevent flea beetle infestations. Since these pests overwinter in the soil, moving tomato plants to a new location each year can disrupt their life cycle and minimize their numbers. Planting crops that are less attractive to flea beetles, such as beans or peas, in the tomato plant's former location can also help prevent a recurrence of the problem.

4. Use Natural Repellents

There are several natural repellents that can help deter flea beetles on tomato plants. One of the most effective options is diatomaceous earth, which is a fine powder made from the fossilized remains of algae. Sprinkling this powder on the soil around the tomato plants will create a barrier that the beetles will find difficult to cross. Another option is to plant herbs such as basil, mint or rosemary around the tomato plants. These plants emit strong odors that will repel flea beetles and other pests.

5. Handpick and Destroy

If your flea beetle infestation is mild, you may be able to control it by handpicking the insects off the plants and destroying them. This method can be time-consuming, but it is an effective way to remove the pests without the use of chemicals. Be sure to check the plants regularly and remove any adult beetles you find before they have a chance to lay eggs and start a new generation of pests.

By using one or more of these methods, you can effectively control flea beetles on your tomato plants without resorting to harsh chemicals or pesticides. With a little persistence and patience, you can enjoy a healthy tomato crop free of these pesky insects.
