How to Keep Tomato Worms off My Tomato Plants

Tomatoes are one of the easiest and most rewarding garden plants to grow. However, every gardener knows the frustration of coming across a tomato worm munching away at the ripening fruit. These green, plump caterpillars can quickly decimate your tomato crop, so it's important to take steps to keep them off your beloved plants. Here are some effective ways to keep tomato worms off your tomato plants.

Hand-pick the Caterpillars

One of the most straightforward methods of controlling tomato worms is to hand-pick them. Check your tomato plants daily, and remove any caterpillars that you find by dropping them into a bucket of soapy water. This method is effective but time-consuming, particularly if you have a lot of tomato plants to care for. Additionally, if you're squeamish about handling insects, this method may not be ideal.

Attract Beneficial Insects

Nature provides us with many beneficial insects that can help keep tomato worms under control. Ladybugs and their larvae are particularly effective at keeping tomato worms at bay, as they eat both the eggs and the caterpillars. Parasitic wasps lay their eggs inside tomato worm larvae, killing them as they mature. To attract beneficial insects to your garden, plant flowering herbs like dill, fennel, and parsley near your tomato plants.

Use Neem Oil Spray

Another method of controlling tomato worms is to use neem oil spray. Neem oil is a natural insecticide that is safe for humans and pets but can be lethal to tomato worms. Simply mix neem oil with water according to the instructions on the package and spray it directly onto your tomato plants. Be sure to cover both the top and bottom of the leaves, as tomato worms often hide underneath them.

Apply Diatomaceous Earth

Diatomaceous earth is a natural powder made from fossilized diatoms, and it can be an effective way to keep tomato worms off your plants. When the powder comes into contact with the tomato worm's soft body, it dehydrates and kills it. To apply diatomaceous earth, sprinkle a fine layer on the soil around the base of your tomato plants. Be sure to reapply after any rainfall or watering, as the powder loses its effectiveness when it gets wet.

Conclusion

With a little effort, you can keep tomato worms off your beloved tomato plants and enjoy a bountiful harvest. Hand-picking, attracting beneficial insects, using neem oil spray, and applying diatomaceous earth are all effective ways to keep these pests at bay. Experiment with different methods to find the one that works best for you and your garden, and enjoy the satisfaction of watching your tomato plants thrive.
