How to Get Rid of Mosquito Larvae in Citronella Plant Water

Updated: April 10, 2022

Citronella plants are known for their ability to repel mosquitoes with their strong scent. Many people use citronella plant water as a natural insect repellent, but sometimes mosquito larvae can still be found in the water. Here are some tips on how to get rid of mosquito larvae in citronella plant water.

1. Change the Water Regularly

One of the easiest ways to prevent mosquito larvae from thriving in citronella plant water is to change the water regularly. Mosquitoes lay their eggs in stagnant water, so by changing the water every few days, you can disrupt their breeding cycle and prevent them from multiplying.

2. Clean the Container

If you notice mosquito larvae in your citronella plant water, it’s important to clean the container thoroughly before refilling it with fresh water. Use a brush or sponge to scrub the sides and bottom of the container, and rinse it with clean water.

3. Add a Mosquito Dunk

Mosquito dunks are small tablets that contain a bacteria called Bacillus thuringiensis israelensis (BTI), which is toxic to mosquito larvae but safe for humans and pets. Simply drop a mosquito dunk into your citronella plant water and it will release BTI over time, killing any mosquito larvae that may be present.

4. Use a Fine Mesh Screen

Another way to prevent mosquito larvae from entering your citronella plant water is to cover it with a fine mesh screen. This will prevent adult mosquitoes from laying their eggs in the water and also stop other insects from contaminating the water.

5. Avoid Overwatering

Overwatering your citronella plant can lead to stagnant water that is prone to mosquito breeding. Make sure you only water your plant when the soil is dry and avoid leaving standing water in the saucer underneath the pot.

By following these tips, you can keep your citronella plant water free of mosquito larvae and enjoy its natural insect-repellent properties without any unwanted visitors.
