How to Kill Ants in Potted Plants without Harming the Plant

Ants are a common problem that many plant owners face. They not only create unsightly ant hills around the pot, but they can also damage the plant’s roots and even bring other pests along with them. While pesticides may seem like the easiest solution, they are not always a safe option for the plant or the environment. Here are some effective and natural ways to kill ants in potted plants without harming the plant:

Cinnamon

Cinnamon is a natural ant repellent that can help get rid of ants in your potted plants. Sprinkle some cinnamon powder around the base of the plant and on the soil surface, and it will deter ants from coming near. Ants have an aversion to the smell of cinnamon, and the powder suffocates them when they come in contact, making it an effective ant killer without harming your plant.

Vinegar

Vinegar is another natural deterrent against ants. Mix one-part vinegar with one-part water and spray it onto the soil surface around the plant, making sure not to cover the plant’s leaves. The vinegar smell will keep the ants away, and spraying the solution in the soil will kill ant eggs, larvae and adult ants.

Baking Soda

Baking soda can also be an effective way to get rid of ants in your potted plants. Mix equal parts of baking soda and sugar, and sprinkle the mixture around the base of the plant and on the soil surface. Ants are attracted to sugar, but baking soda will kill them once they consume the mixture. Repeat every few days for a few weeks until the ant population is eradicated.

Hot Water

Boiling water poured directly onto an ant hill can kill ants in the soil, but it could also harm the plant's roots. Instead, use hot water. Boil a pot of water and let it cool for a few minutes. Then, pour it onto the soil surface around the plant. The hot water will kill ants on contact and not cause any lasting damage to your plant if done carefully.

Diatomaceous Earth

Diatomaceous earth, a type of sedimentary rock made up of fossilized diatoms, is a natural insecticide that is safe for plants. Sprinkle a layer of diatomaceous earth on the soil surface and around the base of the plant. It dehydrates ants, causing them to die, but won't harm the plant. Use food-grade diatomaceous earth instead of swimming pool filter diatomaceous earth.

Conclusion

There are several effective ways to kill ants in potted plants without harming the plant. Cinnamon, vinegar, baking soda, hot water, and diatomaceous earth all work well and are natural, safe, and affordable alternatives to pesticides. Choose the option that works best for you and the extent of the infestation. With regular maintenance and application, you can keep ants out of your potted plants and protect the health of your plants.
