How to Get Rid of Millipedes in Potted Plants

Having millipedes in your potted plants can be a frustrating experience, especially when they start to damage your plants. Millipedes are arthropods that live in soil, and they usually feed on decaying organic matter. They are known to be harmless to humans, but they can cause damage to plants by feeding on the roots, which can lead to stunted growth or death. In this article, we will discuss some effective ways to get rid of millipedes in potted plants.

1. Remove the millipedes manually

If you only have a few millipedes in your potted plant, you can remove them manually. Use a pair of gloves and pick up the millipedes one by one, then dispose of them. This method is time-consuming and may not be effective if you have a large infestation, but it is a good starting point.

2. Dry out the soil

Millipedes thrive in moist soil, so one way to get rid of them is by drying out the soil. This can be done by allowing the soil to dry out completely before watering again. Make sure not to overwater the plant as this will create the perfect environment for millipedes to thrive. You can also add some sand to the soil to improve drainage and reduce moisture content.

3. Use diatomaceous earth

Diatomaceous earth is a natural powder made from the fossilized remains of diatoms, a type of algae. It is effective in killing millipedes as it dehydrates them. To use diatomaceous earth, sprinkle a thin layer on top of the soil and around the base of the plant. Make sure to wear a mask when handling diatomaceous earth as it can cause respiratory problems.

4. Apply insecticides

If the infestation is severe, you may need to use insecticides to get rid of the millipedes. Insecticides containing pyrethrin or permethrin are effective in killing millipedes. However, they are harmful to other organisms such as beneficial insects, pets, and humans. Make sure to follow the instructions on the label carefully and wear protective equipment when handling and applying the insecticide.

5. Keep the area clean

Millipedes are attracted to decaying organic matter, so keeping the area around your potted plant clean is important. Remove any dead leaves, debris, or other decaying matter around the plant. This will reduce the food source for millipedes and make the environment less favorable for them to thrive.

Conclusion

Millipedes can be a nuisance in potted plants, but there are several effective ways to get rid of them. You can remove them manually, dry out the soil, use diatomaceous earth, apply insecticides, and keep the area clean. By following these methods, you can keep your potted plants healthy and free of millipedes.
