How to Get Rid of Ants in My Tomato Plants

Ants can be a nagging problem for gardeners, particularly those who grow tomato plants. While ants themselves do not typically harm the plants, they're often found 'farming' aphids or mealybugs, which feed on the tomato plants. Additionally, ants can disturb the soil, cause damage to the seedlings, and introduce other pests. Thankfully, there are several solutions to get rid of ants in your tomato plants.

Remove Food Sources

Before taking any drastic measures, try to remove any food sources that may be attracting ants to the tomato plants. Ants feast on plant nectar, sugary substances, and carbohydrates. Ripe or rotten fruit on the ground near tomato plants is also a significant attractant. Make sure to remove any fruit, weeds, or fallen leaves nearby. Additionally, properly deadhead tomato plants to prevent blooming unless necessary.

Sprinkle Diatomaceous Earth

Diatomaceous earth is a safe, effective, and chemical-free way to control ants in tomato plants. The product is available at most garden centers and is created by grinding up fossilized shells and algae into a fine powder. The powder's abrasive nature damages the insects' exoskeleton and dehydrates them until they die. Sprinkle onto the soil around the tomato plants and directly on top of any ant mounds.

Use Citrus Peels

Using citrus peels is another practical and eco-friendly solution to get rid of ants in tomato plants. Citrus fruit contains a high amount of citric acid, which is toxic for ants. Place orange or lemon peels around the base of the tomato plants and switch them out every two to three days. This method works best in combination with other solutions, such as diatomaceous earth.

Plant Companion Crops

Planting companion crops alongside tomato plants can help keep ants at bay. Marigold, allium, mint, and basil are some of the plants that naturally repel ants. You can also create a barrier around tomato plants made of such plants to prevent ants from approaching the plants. This method also attracts beneficial insects and pollinators.

Conclusion

Ants are a common problem for tomato plants. They can damage the plants and introduce other pests. However, several effective and eco-friendly solutions can help get rid of ants in tomato plants. Removing food sources, using diatomaceous earth and citrus peels, and planting companion crops are all effective in controlling an ant infestation. By following these methods, you can prevent ant damage to your tomato plants and help them grow healthy and fruitful.
