Mosquito Larvae (Wigglers)
Mosquito larvae, often called "wigglers," are:
- Small, worm-like aquatic organisms
- Usually 1/4 to 1/2 inch long
- Move with a wiggling motion in water
- Hang upside-down at the water surface to breathe
- Visible to the naked eye in standing water
Mosquito Pupae (Tumblers)
Mosquito pupae, often called "tumblers," are:
- Comma-shaped organisms
- Typically darker than larvae
- Move with a tumbling motion when disturbed
- Rest at the water surface
- The stage just before adult mosquitoes emerge
When looking for mosquito larvae and pupae, check standing water sources like:
- Swimming pools
- Bird baths
- Buckets or containers
- Drainage ditches
- Plant saucers
- Rain gutters
If you see small creatures moving in standing water, there's a good chance they're mosquito larvae or pupae.
