Life Cycle of a Mosquito
Understanding mosquito biology can act as your first line of defense against these persistent pests. When you know how mosquitoes develop and reproduce, you can target them more effectively and protect your family from potential health risks.
How long do mosquitoes live?
The length of the mosquito life cycle varies between species and is dependent upon environmental conditions such as temperature and moisture. Male mosquitoes typically live only 6-7 days, feeding exclusively on plant nectar. Female mosquitoes, however, can live 6 weeks on average, with some surviving up to 5 months under ideal conditions. The life cycle of all mosquitoes is comprised of the egg, larval, pupal, and adult stages.

The Four Stages of the Mosquito Life Cycle
All mosquito species complete the same four-stage development process, known as complete metamorphosis. The first three stages require water, making moisture control essential for prevention.
Stage 1: Mosquito Eggs
Mosquito eggs appear as tiny, dark, oval specks, roughly 1mm long, barely visible to the naked eye. Depending on the species, females lay eggs either individually along water edges or in clustered rafts floating on the surface. Some eggs are highly resilient, capable of remaining viable for months, or even years, in dry conditions.
Most eggs hatch within 24-48 hours when exposed to water, but some species produce drought-resistant eggs that wait for ideal flooding conditions. This survival strategy explains why you might see sudden mosquito population explosions after heavy rains.
Stage 2: Mosquito Larvae
Mosquito larvae enter their aquatic phase immediately after hatching, spending this stage suspended head-down at the water's surface while breathing through siphons, small air tubes that function like snorkels. Known as the "wiggler" stage due to their characteristic swimming motion, larvae grow to about 5mm in length and remain in this stage for 4 to 14 days, depending on factors like temperature and food availability. Their development includes four distinct growth phases, called instars. When threatened, larvae instinctively dive deeper into the water using an "S"-shaped motion, a reflex designed to avoid danger.
Larvae feed on microorganisms, algae, and organic debris in the water. They're filter feeders, constantly consuming microscopic particles that help them grow and develop.
Stage 3: Mosquito Pupae
The pupal stage is the transformation period where larvae develop into adult mosquitoes. Pupae, often called "tumblers" due to their rolling escape movements, are comma-shaped with large heads. They do not feed but still require access to air at the water's surface, breathing through trumpet-shaped tubes. This stage typically lasts 1-4 days, and pupae are highly sensitive to disturbances like light and movement.
During this stage, the mosquito's body completely reorganizes. Wings, legs, and reproductive organs develop inside the pupal case, preparing for adult emergence.
Stage 4: Adult Mosquitoes
Once adult mosquitoes emerge from their pupal cases, they rest on the water's surface, allowing their wings to dry and harden. Within hours, they are ready for flight and reproduction. It's crucial to note that only female mosquitoes bite, as they require blood meals to produce eggs, while males exclusively feed on plant nectar and sugars. A single female can lay between 100 to 200 eggs per blood meal. Most species have a flight range of 1 to 10 miles, though some can travel up to 40 miles. Mating occurs rapidly after emergence, a necessity given their short adult lifespan.
Female mosquitoes locate hosts by detecting carbon dioxide, body heat, and specific chemical compounds humans and animals exhale. After feeding, they seek suitable water sources to lay their next batch of eggs, completing the cycle.

Mosquito Breeding Grounds Around Your Home
Almost any standing water can support mosquito development, including sources you might overlook:
Obvious breeding sites:
-
Birdbaths and pet water bowls
-
Rain barrels and water storage containers
-
Swimming pools (improperly maintained)
-
Ponds and water features
Hidden breeding locations:
-
Clogged gutters holding stagnant water
-
Corrugated downspout extensions
-
Flower pot saucers and plant containers
-
Tire swings and outdoor equipment collecting rainwater
-
Tree holes and hollow stumps
Professional Mosquito Control
Mosquitoes go through a rapid life cycle, from eggs laid in standing water to adults ready to bite in just days. Interrupting this cycle is key to effective mosquito control. If mosquitoes are making your outdoor spaces unbearable or you're concerned about health risks, contact your local Orkin branch for help getting rid of infestations. An Orkin Pro can assess your property, identify breeding sources, and implement comprehensive mosquito control program tailored to your specific situation.
