Updated: June 11, 2022

Catmint is a popular herb in the mint family, known for its attractive foliage and delicate flowers. It’s also a favorite of cats, who love to rub against its leaves and roll in its fragrance. However, like any other plant, catmint is susceptible to pests that can damage or even kill it. In this article, we’ll explore the most common catmint plant pests, how to identify them, and the best treatment methods.

Spider Mites

Spider mites are tiny arachnids that can cause significant damage to your catmint plants. They are often found on the underside of leaves and can be identified by the fine webs they spin. Spider mites feed on plant sap, causing the leaves to turn yellow and fall off. To treat spider mites, spray your catmint plants with a stream of water to dislodge them. You can also use neem oil or insecticidal soap to kill them.


Aphids are small, soft-bodied insects that suck the sap from your catmint plants. They can be identified by their pear-shaped bodies, long antennae, and two cornicles or “tailpipes” on their backs. Aphids often congregate on new growth and flower buds, causing them to distort or curl up. To treat aphids, you can use insecticidal soap, neem oil or a strong jet of water to wash them off your plants.


Whiteflies are small, winged insects that feed on the sap of your catmint plants. They can be identified by their white wings and yellow bodies. Whiteflies excrete a sticky substance called honeydew that attracts ants and can cause fungal diseases on your plants. To treat whiteflies, use insecticidal soap or a strong jet of water to knock them off your plants.


Thrips are tiny, slender insects that feed on your catmint plants by sucking their sap and scraping their surfaces. They are often found on flowers and can be identified by their fringed wings and narrow bodies. Thrips can cause leaf discoloration, deformation, and stunting of plant growth. To treat thrips, use insecticidal soap or neem oil.


How can I prevent pests from attacking my catmint plants?

The best way to prevent pests from attacking your catmint plants is to keep them healthy and vigorous. Make sure they are planted in well-draining soil and receive adequate water and sunlight. You can also prune off any damaged or diseased leaves to prevent the spread of pests.

Are there any natural remedies for catmint plant pests?

Yes, there are several natural remedies for catmint plant pests, including insecticidal soap, neem oil, and horticultural oils. You can also use companion planting to attract beneficial insects like ladybugs and lacewings that will eat the pests.

Can I use chemical pesticides on my catmint plants?

It’s not recommended to use chemical pesticides on your catmint plants as they can harm beneficial insects and contaminate the environment. However, if you must use them, read the label carefully and follow the instructions for safe use.

In conclusion, catmint is a beautiful herb that requires careful attention to keep away pests. By following the identification and treatment guide provided in this article, you can keep your catmint plants healthy and thriving. Remember to always opt for natural remedies over chemical pesticides and preventive measures over reactive ones.
