How to Get Rid of Beetles on Tomato Plants

tomato plants image by JLycke from

There are several different types of pests that can bother your tomato plants. Beetles are one of those types. You may find blister beetles, Colorado potato beetles, or flea beetles on your tomato plants. These beetles mainly eat the leaves of the tomato plant, leaving behind small and large holes. If you see these beetles, you will want to get rid of them as soon as possible.

Pour water in your bucket. Then add the dish soap. This is the base of your homemade insecticidal soap.

Drip the vegetable oil and neem oil into your bucket. Mix all of the ingredients. The vegetable oil helps the insecticidal soap stay on the tomato plant, while the neem oil works as an all-natural pesticide to kill the beetles.

Transfer your insecticidal soap to an empty spray bottle.

Spray your tomato plants with your homemade insecticidal soap. Concentrate on the leaves as this is where you will find most of the beetles.

Repeat every four to five days, or after a rainfall. This insecticide will both kill the beetles that are on the tomato plants and keep new beetles from feasting on the leaves.

Homemade Natural Spray For Flea Beetles On Tomato Plants

A potent spray containing garlic and pepper can repel flea beetles and a variety of other pest insects. One spray that may repel or kill flea beetles is made by combining 2 parts rubbing alcohol, 5 parts water and 1 tablespoon of mild, biodegradable liquid dish-washing soap. You can also attach the trap to a wooden stake near the plant. Young plants are potentially protected using floating row covers, gauze or mesh. Flea beetles are especially drawn to plants in the cabbage family, so planting a few of these plants nearby can draw the pests away from the tomatoes. Using a handheld vacuum to remove flea beetles from the tomato plants daily can also reduce pest numbers.


Boric acid is another natural product you could use as an insecticide.


You can use chemical insecticides to get rid of the beetles on your tomato plants, but be aware that some of the chemicals may seep in to the plant. When you eat the tomato, you eat the chemicals.
