How to Get Rid of Mosquito Larvae in Freshwater Plant Water

Updated: March 25, 2023

Mosquitoes are not only annoying, but they can also carry harmful diseases. While many people use insecticides to get rid of adult mosquitoes, it’s important to also address the issue of mosquito larvae in freshwater plant water. Here are some effective ways to eliminate mosquito larvae from your plant water.

1. Remove stagnant water

Mosquitoes lay their eggs in stagnant water, so the first step is to remove any standing water in your plant containers. This includes emptying any saucers or trays that may have collected water. Make sure to do this regularly, at least once a week.

2. Use mosquito dunks

Mosquito dunks are small tablets that contain Bacillus thuringiensis israelensis (BTI), a naturally occurring bacteria that kills mosquito larvae. These are safe for use in freshwater plant water and can be found at most gardening stores.

To use mosquito dunks, simply drop one tablet into the water of each plant container. The tablet will slowly dissolve and release the BTI over time, effectively killing any mosquito larvae.

3. Add fish to your plant water

Certain types of fish, such as guppies and goldfish, are known to eat mosquito larvae. Adding these fish to your plant water can help keep the mosquito population under control.

Keep in mind that adding fish to your plant water requires careful consideration of the size of the container and the type of plants you have. Some plants may not tolerate fish or may require specific types of fish.

4. Use essential oils

Certain essential oils have been found to repel mosquitoes and their larvae. These include citronella, lavender, peppermint, and eucalyptus oil.

To use essential oils, add a few drops to your plant water. Be sure to research the appropriate amount for your specific plant and container size, as too much oil can harm your plants.

5. Keep your plant water clean

Regularly cleaning your plant containers and changing the water can help prevent mosquitoes from laying their eggs in the first place. Make sure to also remove any dead leaves or debris from the surface of the water.

FAQ

Can mosquito larvae harm my plants?

Mosquito larvae do not harm plants directly, but they can indirectly harm them by attracting other pests that may feed on the larvae.

Is BTI safe for my plants?

BTI is safe for most plants when used in the recommended dosage. However, it’s always best to research the specific needs of your plants before using any products.

Can I use insecticides to kill mosquito larvae?

Insecticides are not recommended for use in freshwater plant water as they can harm beneficial insects and other wildlife. Additionally, many insecticides contain harmful chemicals that can be toxic to humans and pets.
