Introduction

Blister bugs are small insects that can cause significant damage to tomato plants by feeding on their leaves and stems. They are named after the blisters they cause on human skin if they come in contact with it. In this article, we will discuss how to get rid of blister bugs on tomato plants.

Identifying Blister Bugs

The first step in getting rid of blister bugs is to identify them. Blister bugs are easily recognizable by their elongated bodies and characteristic black and white coloring. They are usually 1/2 inch in length and have long antennae. Blister bugs feed on the sap of tomato plants, causing the leaves to wilt and turn brown. If left unchecked, they can cause significant damage to the plant.

Preventing Blister Bugs

The best way to deal with blister bugs is to prevent them from infesting your garden in the first place. You can do this by using row covers to protect your tomato plants from these insects. Row covers are available at most garden centers and can be placed over young plants to prevent insects from reaching them. Another effective method is to plant companion plants that repel blister bugs, such as marigolds, petunias or calendula.

Manual Removal

If you already have blister bugs infesting your tomato plants, one option is to remove them by hand. Wear gloves to protect your skin and simply pick off the bugs and drop them into a bucket of soapy water. This will kill the bugs and prevent them from damaging your plants further. Repeat this process every few days to ensure all the bugs have been removed.

Organic Spray

If you would prefer not to remove the bugs by hand, you can use an organic spray to get rid of them. Mix one tablespoon of dish soap with one gallon of water and spray the solution onto the affected leaves of your tomato plants. The soap will coat the bugs, suffocating them and preventing them from feeding on your plants. Repeat this every seven to ten days until the infestation has been eliminated.

Chemical Insecticides

If you have a severe blister bug infestation, you may need to resort to chemical insecticides. These are available at most garden centers and can be effective at killing blister bugs. However, they should be used with caution, as they can also harm beneficial insects and pollinators. Be sure to read the label carefully and follow the instructions for safe use.

Conclusion

Blister bugs can be a nuisance for tomato growers, but they can be controlled by following the tips presented in this article. Prevention is the best way to deal with blister bugs, but if they do appear on your plants, manual removal or organic sprays can be effective. Chemical insecticides should only be used as a last resort.
