What Kills Stink Bugs on Tomato Plants?

Stink bugs are a common problem that many tomato growers face. These bugs feed on the fruit, causing significant damage to the plant's yield. To prevent stink bug infestations, it is essential to take the proper precautions early on in the growing season. However, if you already have an infestation, there are several methods you can use to eliminate stink bugs on tomato plants.

Handpicking

Handpicking stink bugs is one of the most traditional ways to remove them from tomato plants. This method involves physically picking bugs off the foliage and dropping them into a bucket of soapy water. It is effective for small-scale infestations, as it can be time-consuming for larger gardens. To avoid harming the plant, handle tomato foliage with care, and avoid damaging the fruit.

Natural Predators

Encouraging the presence of natural predators is an effective way of controlling stink bugs on tomato plants. Common predators of stink bugs include birds, spiders, and praying mantises. You can attract these predators to your garden by planting flowers that attract pollinators, like sunflowers, or keep bird feeders near your tomato plants.

Insecticide Sprays

Insecticide sprays can be effective in controlling stink bugs on tomato plants, but they should be used with caution. Some insecticides can harm beneficial insects and pollinators, so it is essential to choose a product that is labeled safe for use on edible plants. Always read and follow the instructions carefully, and avoid spraying during peak pollinator activity.

Neem Oil

Neem oil is an organic and effective way to kill stink bugs on tomato plants. This oil is derived from the seeds of the neem tree and is safe for use on edible plants. Mix a tablespoon of neem oil with a quart of water and spray the mixture on the foliage of the tomato plant. Neem oil works by disrupting the insect's natural hormonal balance, causing them to stop feeding and eventually die.

Diatomaceous Earth

Diatomaceous earth is a powdery substance made up of fossilized algae. When insects come into contact with it, it damages their exoskeleton, leading to dehydration and death. To use diatomaceous earth, apply a light dusting of the powder to the foliage of the tomato plant. Be sure to reapply after rain or watering, as it can be washed away quickly.

Conclusion

Stink bugs can cause significant damage to tomato plants, but with the right precautions, you can prevent their infestation. If you already have an infestation, start with handpicking and attracting natural predators. If that doesn't work, then consider insecticide sprays, neem oil, and diatomaceous earth. Whatever method you choose, remember to read and follow the instructions carefully to avoid harming beneficial insects and pollinators.
