How to Get Rid of Mosquito Larvae in Christmas Plant Water

Updated: April 10, 2022

Christmas plants are a staple in many households during the holiday season. However, stagnant water in the plant’s container can become a breeding ground for mosquitoes. Mosquito larvae can develop in any standing water for more than four days, and they are not only annoying but also dangerous as they can transmit diseases. Here are some tips on how to get rid of mosquito larvae in Christmas plant water.

Change the water regularly

The most effective way to prevent mosquito larvae from developing in Christmas plant water is to change the water regularly. Mosquitoes need stagnant water to lay their eggs, and by changing the water frequently, you disrupt their breeding cycle. Ensure that you empty the entire container of water and refill it with fresh water.

Add mosquito dunks

Mosquito dunks are a safe and effective way to get rid of mosquito larvae in Christmas plant water. They contain a bacteria known as Bacillus thuringiensis israelensis (BTI), which is toxic to mosquito larvae but harmless to humans and pets. The bacteria release toxins that target the larvae’s digestive system, killing them within hours. Mosquito dunks can be purchased from hardware stores or online, and they come in small donut-shaped tablets that can be dropped into the plant’s container.

Use essential oils

Essential oils like lavender, peppermint, and citronella are known for their ability to repel mosquitoes. Adding a few drops of these oils to Christmas plant water can help deter mosquitoes from laying their eggs in the water. However, it’s important to note that essential oils can be harmful to pets if ingested. Therefore, use them sparingly and keep them out of reach of pets.

Keep the container covered

Covering the Christmas plant’s container with a lid or plastic wrap can prevent mosquitoes from accessing the stagnant water. This method works best if the plant is not in direct sunlight, as the plastic wrap can cause the water to heat up and promote bacterial growth.

Keep the plant indoors

If you’re struggling to get rid of mosquito larvae in Christmas plant water, consider moving the plant indoors. Mosquitoes prefer warm and humid environments, and bringing the plant inside can reduce their breeding opportunities.


Getting rid of mosquito larvae in Christmas plant water is essential for preventing mosquito-borne diseases. By changing the water regularly, adding mosquito dunks, using essential oils, keeping the container covered, or moving the plant indoors, you can effectively control mosquito populations.


Are mosquito dunks safe for pets?

Yes, mosquito dunks are safe for pets as they contain bacteria that are toxic to mosquito larvae but harmless to humans and pets.

How often should I change the water in my Christmas plant’s container?

You should change the water every three to four days to prevent mosquito larvae from developing.

Do essential oils repel all types of mosquitoes?

No, essential oils only repel certain types of mosquitoes. It’s best to do research on which essential oils are effective against the species of mosquitoes in your area.

Can I reuse a mosquito dunk?

No, mosquito dunks are designed for one-time use only. Once they dissolve completely in water, you need to replace them with a new one.
