What Kills Ants in Potted Plants?

Ants can be beneficial in gardens as they aerate the soil and eat other pests like aphids. However, they can also become a nuisance when they start to invade your potted plants. Not only can they damage the roots and the plants, but they can also attract other pests like mealybugs or scale insects. So, what can you do to get rid of ants in your potted plants? Here are some solutions.

Boric Acid

Boric acid is a common insecticide that is effective in killing ants. It is a white powder that can be found in hardware or garden stores. Mix the boric acid with sugar and water to create a bait that will attract the ants. Once the ants consume the bait, the boric acid will start to disrupt their digestive system, eventually killing them. However, be careful when using boric acid around pets and children as it can be toxic.

Diatomaceous Earth

Diatomaceous earth is a natural product made from the remains of tiny marine organisms called diatoms. It is a white powder that is capable of killing ants and other pests by dehydrating them. Sprinkle diatomaceous earth around the base of your potted plants or directly onto the soil. When ants come into contact with the powder, it will stick to their bodies and cause them to dehydrate and die. Diatomaceous earth is safe for humans and pets, but make sure to use food-grade diatomaceous earth to avoid any harmful chemicals.

Vinegar

Vinegar is a natural and safe product that can repel ants from your potted plants. Mix equal parts of white vinegar and water and spray the solution around the base of your potted plants. The strong smell of the vinegar will discourage the ants from approaching your plants. However, be careful not to spray the solution directly onto your plants as vinegar can be harmful to some types of plants.

Cinnamon

Cinnamon is another natural product that can repel ants from your potted plants. Sprinkle ground cinnamon around the base of your potted plants or directly onto the soil. The strong smell of the cinnamon will discourage the ants from entering and damaging your plants. Additionally, cinnamon is a great natural fungicide and can protect your plants from fungal infections.

Insecticidal Soap

Insecticidal soap is a type of soap that can be used to control pests like ants in your potted plants. It is made from natural ingredients and is safe to use around pets and children. Spray the insecticidal soap onto your plants and around the base of your pots to kill any ants that are present. The soap works by suffocating the ants and disrupting their respiratory system, eventually killing them.

Overall, there are several natural and safe solutions to kill ants in potted plants. Using boric acid, diatomaceous earth, vinegar, cinnamon or insecticidal soap can help you get rid of ants while keeping your plants safe and healthy. However, prevention is always better than cure, so make sure to keep your plants clean and free of any excess food or moisture that may attract ants in the first place.
