How to Get Rid of Thrips in Fire Stick Plant

Updated: May 7, 2022

Fire stick plant, also known as pencil cactus or Euphorbia tirucalli, is a popular houseplant with striking red and yellow coloration. However, it’s not uncommon for this plant to become infested with thrips, tiny insects that can damage the leaves and sap the plant’s energy. If you’re dealing with a thrip infestation in your fire stick plant, here are some steps you can take to get rid of them.

Step 1: Identify the Problem

Thrips are tiny insects, usually only about 1-2mm long. They are slender and have fringed wings, which makes them look like they are covered in fur. You might not see thrips on your fire stick plant immediately, but the signs of their presence will become apparent over time.

Thrips feed by puncturing the leaves of plants and sucking out the sap. This causes small, silvery spots on the leaves, which can eventually turn brown and crispy. If you notice these spots on your fire stick plant, you may have a thrip problem.

Step 2: Isolate Infected Plants

If you have multiple plants in your home or garden, it’s essential to isolate any plants that show signs of thrip infestation. Thrips can easily spread from one plant to another, so keeping infected plants away from healthy ones is crucial.

Step 3: Cut Back Infected Parts

If you notice thrip damage on your fire stick plant, it’s essential to remove any infected parts as soon as possible. Use sharp pruning shears to cut off any stems or leaves that show signs of damage. Be sure to dispose of these cuttings carefully and avoid composting them, as this could spread the thrips.

Step 4: Use a Natural Insecticide

There are several natural insecticides that you can use to get rid of thrips on your fire stick plant. One of the most effective is neem oil, which is derived from the neem tree. Neem oil can be sprayed directly onto the plant to kill thrips and other pests.

Another natural insecticide is insecticidal soap, which is made from potassium salts of fatty acids. Insecticidal soap works by dissolving the protective coating on thrips, causing them to dehydrate and die.

Step 5: Monitor Your Plant

After taking steps to eliminate thrips from your fire stick plant, it’s important to monitor the plant carefully for any signs of re-infestation. Check the leaves regularly for new damage or silvery spots. If you notice any signs of thrip activity, repeat the treatment process.


Can thrips kill my fire stick plant?

Thrips can cause significant damage to fire stick plants, but they are not usually fatal. However, if left untreated, a severe thrip infestation can weaken the plant and make it more susceptible to other pests and diseases.

How do I prevent thrips from infesting my fire stick plant?

The best way to prevent thrips is to keep your fire stick plant healthy and stress-free. Provide adequate water and sunlight, avoid over-fertilizing, and keep the plant free of dust and debris. You can also use sticky traps or neem oil spray as a preventative measure.

Are thrips harmful to humans?

Thrips are not harmful to humans and do not bite or sting. However, they can cause skin irritation in some people who are allergic to their saliva.

In conclusion, thrips can be a nuisance for fire stick plant owners, but with proper care and attention, you can get rid of them and keep your plant healthy. By following these steps and monitoring your plant carefully, you can enjoy the beauty of your fire stick plant without the worry of thrips.
