How to Control Mosquito Larvae Without Chemicals

Mosquitoes are common yard pests that feed solely on blood. In addition to inflicting painful, itchy bites, mosquitoes also spread diseases like West Nile virus and parasites like wolf worm. Their larvae develop in shallow, stagnant water and develop into pupae that swim to the surface to breathe. By preventing or killing mosquito larvae in your yard, you lessen your likelihood of contracting a mosquito-borne illness as well as prevent annoying bites.

Things You'll Need

Apple cider vinegar
Citronella plants

Instructions

- 1
  Clean your gutters and clear your yard of debris like old tires, wood piles and dog toys. Mosquito larvae can develop in a very small amount of water, and debris tends to fill with water. Gutters are among the most common locations for mosquitoes to lay eggs because they provide a moist, quiet hiding place for the larvae to develop.
- 2
  Dump water from bird baths, dog bowls and other water receptacles daily. This discourages mosquitoes from laying eggs and kills any larvae that have taken up residence in the water.
- 3
  Pour a small amount of apple cider vinegar in areas where mosquito larvae are developing. This substance is nontoxic to animals but will kill the mosquito larvae. It will not harm plants so is safe to use liberally around the yard.
- 4
  Plant citronella around your yard. Mosquitoes hate the smell of citronella and will avoid yards with citronella plants. Larvae that hatch in these yards will quickly leave. Citronella herbs have a pleasant, slightly lemony smell. Create a barrier of these plants around your yard, planting them in any locations you commonly notice mosquitoes and their larvae.
