How to Get Rid of Spider Mites in Devils Trumpet Plant

Updated: October 6, 2022

The Devil’s Trumpet plant, also known as Datura, is a beautiful and exotic plant that has been used in traditional medicine for centuries. Unfortunately, it is also a common target for spider mites, a tiny pest that can cause extensive damage to the plant if not dealt with promptly. In this article, we’ll discuss how to identify spider mites, the damage they can cause, and most importantly, how to get rid of them.

Identifying Spider Mites

Spider mites are tiny pests that are difficult to spot with the naked eye. They are usually about the size of a grain of sand and can be red, brown, or yellow in color. One of the easiest ways to identify spider mites is to look for small webs on the undersides of leaves or at the base of the plant. These webs are created by the mites as they move around the plant.

Damage Caused by Spider Mites

Spider mites feed on the sap of plants, which can cause significant damage over time. The first signs of damage are usually yellow or brown spots on the leaves, which can eventually lead to leaf drop. As the infestation progresses, the plant may become stunted and stop producing flowers.

Getting Rid of Spider Mites

There are several effective methods for getting rid of spider mites in Devil’s Trumpet plants. Here are some of the most popular options:

1. Pruning

If you notice an infestation early on, you may be able to remove the affected leaves or branches by pruning them off. Be sure to dispose of these cuttings away from other plants to prevent the mites from spreading.

2. Water Spray

Spider mites thrive in dry environments, so one way to combat them is to increase humidity around your plant. You can do this by misting the leaves with water or placing a saucer filled with water near the plant. Be careful not to overwater the plant, as this can lead to other problems.

3. Insecticidal Soap

Insecticidal soap is a safe and effective method for controlling spider mites. It works by suffocating the mites and preventing them from reproducing. To use insecticidal soap, mix it according to the instructions and spray it directly onto the affected areas of the plant.

4. Neem Oil

Neem oil is another natural pesticide that can be used to control spider mites. It works by disrupting the mites’ reproductive cycle and preventing them from laying eggs. To use neem oil, mix it according to the instructions and spray it onto the affected areas of the plant.

Preventing Spider Mite Infestations

The best way to deal with spider mites is to prevent them from infesting your plants in the first place. Here are some tips for preventing spider mite infestations:

  • Keep your plants well-watered to increase humidity
  • Avoid over-fertilizing your plants, as this can attract pests
  • Keep your plants clean by regularly wiping down leaves with a damp cloth
  • Inspect new plants carefully before bringing them indoors


Can spider mites be harmful to humans?

Spider mites are not harmful to humans, but they can cause allergic reactions in some people. If you have sensitive skin, it’s best to wear gloves when handling infested plants.

How often should I apply insecticidal soap or neem oil?

Follow the instructions on the product label for best results. In general, you may need to apply these treatments every 7-10 days until the infestation is under control.

Will pruning my Devil’s Trumpet plant harm it?

Pruning is generally safe for Devil’s Trumpet plants, but it’s important to only remove affected leaves or branches. Cutting back too much can harm the plant and prevent it from blooming.

Can I use chemical pesticides to control spider mites?

Chemical pesticides can be effective against spider mites, but they can also harm beneficial insects and pollinators. If you do choose to use a chemical pesticide, be sure to follow the instructions carefully and avoid using it near other plants or bodies of water.
