Leafhoppers are a danger to your cannabis plants, and you should get rid of them as soon as you notice their presence. These pests feed on the cannabis leaves. Even if you cannot see them, there are symptoms that should alert you about their presence. These include leaves that have pale or brown spots. Even if the leaf hasn’t been eaten away, this should be a good sign.
Unfortunately, there are more than 20,000 species of leafhoppers and they can attack your plants in different forms. These pests tend to attack plants during the dry season as they seek out the moisture in the plants. Species don’t matter when getting rid of the leafhoppers. Most remedies will get rid of any species of leafhoppers.
How do you get rid of them and keep your cannabis plants safe?
You should make a point and check your plants all the time, especially during the dry season. The best prevention is to identify the pests as soon as they appear, so you can take preventive measures to keep them away.
Check all around the plants and under the leaves too.
- Beneficial Insects
These are insects that are good for your garden. They include ladybugs, parasitic wasps, lady beetles, and lacewings. These insects feed on the leafhoppers. While you can get beneficial insects like ladybugs and release them in your garden to eat the pests, they tend to fly away in a day or two.
- Insecticidal Soaps
One of the best options you have to deal with these pests is using insecticidal soaps or fatty acid salts. These usually make the outer shell of the pests weak.

These are insecticides that can be sprayed on different vegetable gardens. They are extremely toxic to humans, so you have to be careful when using them. Spray the leaves carefully, especially underneath. One of the problems with pyrethrin is that it’s dangerous to bees. Therefore, it’s advisable to use them only as a last resort.
