The Mosquito Life Cycle
A mosquito has four stages of life:
1. Egg: Once laid in water, eggs will hatch in 2 to 3 days.
2. Larva: A mosquito larva looks like a tiny wiggling worm in the water.
3. Pupa: A larva becomes a pupa and the adult mosquito develops inside.
4. Adult: Total development time from egg to adult can be less than 1 week during periods of warm weather. The average mosquito will live for about 2 weeks.
Mosquito fish are an effective and natural method of controlling mosquitoes. They are small, freshwater fish (1-2 inches long) that eat mosquito larvae. Mosquito fish are ideal for controlling mosquito larvae in backyard ponds, birdbaths, fountains, animal troughs, unused swimming pools and other standing water sources.
Mosquito fish should never be placed in any natural habitat such as lakes, streams, rivers or creeks. They are greedy eaters, so by placing them into natural waterways, they may impact natural species and disrupt the balance of life.
Mosquito fish may be picked up free of charge at different locations throughout San Diego County.
