Your Guide to Mosquito Larvae: How to Identify and Help Kill Them

Mosquito larvae are small, wormlike pests that live in standing water and grow into the biting mosquitoes that bother New Jersey homeowners every summer. You can identify mosquito larvae by their wriggling movement and tube-like shape as they hang near the water surface. If you remove or treat the water where larvae develop, you can stop thousands of mosquitoes before they ever become adults. For ongoing protection, our mosquito control program keeps your yard protected all season.

What Are Mosquito Larvae?

Mosquito larvae are the immature stage of mosquitoes. According to the CDC, larvae hatch from eggs laid in standing water. They stay underwater and feed on algae and organic matter until they grow into pupae and later become biting adults.

Larvae are found in water sources as small as a bottle cap.

What Mosquito Larvae Look Like

You can identify mosquito larvae by these features:

• Wiggling movement when disturbed

• Small tube-like bodies

• A head that is darker than the rest of the body

• Visible breathing tube at the surface

• Usually hang just below the water line

They are sometimes called “wigglers” because of how they move.

Where Mosquito Larvae Hide and Thrive

Mosquito larvae only need a small amount of standing water. Common hotspots in New Jersey include:

• Buckets

• Old flowerpots

• Clogged gutters

• Birdbaths

• Tires

• Pool covers

• Wheelbarrows

• Drainage areas

• Trash can lids

• Kids’ toys

• Low spots in lawns

• Tarps that collect rain

Rutgers University confirms that standing water is the top cause of mosquito populations in residential areas.

How To Kill Mosquito Larvae in Water

Stopping larvae is one of the most effective ways to reduce mosquitoes on your property. Here are the best methods:

1. Remove Standing Water

Dump and clean water-holding items every 48 to 72 hours.

2. Scrub Containers

Scrubbing breaks mosquito eggs attached to surfaces.

3. Use Mosquito Dunks or Larvicides

These products use ingredients approved by the EPA and are safe when used correctly. They target larvae without harming pets or wildlife.

4. Fix Drainage Issues

Level low spots and clear gutters so water cannot sit for days.

5. Keep Pools and Ponds Circulating

Mosquitoes cannot breed in flowing or filtered water.

When larvae are controlled early, adult mosquito populations drop significantly. Homeowners often see the biggest improvement when they combine water removal with professional yard treatments.

Our EPA-approved mosquito barrier treatments help reduce adult mosquitoes and treat areas where they commonly rest. Licensed DEP technicians apply very low toxicity amounts safely and responsibly. Learn more about how we protect your yard with our mosquito services.
