How to Get Rid of Mosquito Larvae in Fishbone Prayer Plant Water

Updated: December 23, 2022

If you have a fishbone prayer plant, you may have noticed mosquito larvae in the water. These larvae can be a nuisance and potentially harmful to your plant’s health. Fortunately, there are several ways to get rid of mosquito larvae in your plant’s water.

Why Are Mosquito Larvae in My Plant’s Water?

Mosquitoes lay their eggs in standing water, including the water in your plant’s pot. The larvae hatch from these eggs and feed on microorganisms in the water. While they don’t harm the plant directly, they can cause problems if left unchecked. Mosquito larvae can clog the roots of your plant, leading to root rot and other issues.

How to Get Rid of Mosquito Larvae

1. Change the Water Frequently

One of the easiest ways to prevent mosquito larvae from growing in your plant’s water is to change the water frequently. This will prevent any eggs from hatching and will also help keep the water clean and fresh for your plant. Aim to change the water at least once a week, or more often if you notice any larvae.

2. Use Mosquito Dunks

Mosquito dunks are small tablets that contain a bacteria called Bacillus thuringiensis israelensis (BTI). This bacteria is harmless to humans and pets but is deadly to mosquito larvae. Simply drop one or two dunks into your plant’s water, and they will dissolve over time, releasing the BTI bacteria into the water. This will kill any mosquito larvae present and prevent new ones from hatching. Mosquito dunks can be purchased at most garden centers and online.

3. Add a Mosquito Fish

If you have a larger container or pond, you may want to consider adding a mosquito fish. These small fish feed on mosquito larvae and can help keep the population under control. Mosquito fish can be purchased at pet stores or online and are relatively easy to care for.

4. Use a Mosquito Netting

If you don’t want to change the water frequently or use chemicals, you can cover the surface of the water with a fine mesh mosquito netting. This will prevent mosquitoes from laying their eggs in the water, and any larvae that hatch will be trapped under the netting and unable to reach the surface. This method is best suited for smaller containers or plants.


Are mosquito dunks safe for my plant?

Yes, mosquito dunks are safe for most plants. The BTI bacteria is harmless to plants, animals, and humans.

How often should I change my plant’s water?

Aim to change the water at least once a week, or more often if you notice any mosquito larvae.

Can I use bleach to kill mosquito larvae?

Bleach can be effective at killing mosquito larvae, but it can also harm your plant if used in high concentrations. It’s best to use a more targeted solution like mosquito dunks or a mosquito fish.

How do I know if my plant has mosquito larvae?

Look for small, wriggling larvae in the water of your plant’s pot. They may also be visible on the surface of the water.

In conclusion, getting rid of mosquito larvae in your fishbone prayer plant’s water is essential for your plant’s health and your own comfort. By changing the water frequently, using mosquito dunks, adding a mosquito fish, or using a mosquito netting, you can keep these pests under control and enjoy a healthy plant.
