Mosquito Life Cycle by Mosquito Sheriff

Lifecycle of a Mosquito

Understanding the lifecycle of a mosquito can help in applying effective control measures to reduce their population and the spread of mosquito-borne diseases. The mosquito lifecycle consists of four distinct stages: egg, larva, pupa, and adult.

1. Egg Stage

  • Where Laid: Female mosquitoes lay their eggs on or near water surfaces, such as in ponds, marshes, or containers holding water.
  • Characteristics: Depending on the species, eggs can be laid singly or in clusters called rafts. They can hatch within 48 hours or remain dormant until favorable conditions arise.

2. Larva Stage

  • Hatching: Eggs hatch into larvae, commonly known as “wigglers” due to their movement in water.
  • Habitat: Larvae live in water and feed on organic material, microorganisms, and plant matter.
  • Development: They go through four growth stages known as instars, molting between each stage. This period can last from a few days to several weeks, depending on environmental conditions.

3. Pupa Stage

  • Transformation: After the larval stages, mosquitoes enter the pupal stage, referred to as “tumblers” because of their tumbling motion in the water.
  • Characteristics: Pupae do not feed and are primarily a transition stage where the mosquito develops into its adult form. This stage typically lasts a few days.

4. Adult Stage

  • Emergence: The adult mosquito emerges from the pupal case and rests on the water surface until it is strong enough to fly.
  • Feeding: Adult female mosquitoes seek blood meals to obtain the necessary nutrients for egg production, while males feed on nectar.
  • Lifespan: Adults can live from a few weeks to several months, depending on species, climate, and availability of food.

By understanding each stage of the mosquito lifecycle, targeted control measures can be applied to interrupt their development and reduce their populations. This is crucial in managing the risks associated with mosquito-borne diseases.


– Mosquitos are Coming is what my technician just called to tell me – thanks for the reminder.  I renewed my annual contract because once you’ve gotten rid of mosquitos you can’t go back!

Mosquitos Are Coming!

– I love what they are doing! Totally Behind them! If each spray can help other communities and also solve your problems too without any extra cost. What else one can ask for. I have booked them for the entire season. So Excited!!

– I was looking for a Non-Toxic/Natural way to handle the mosquitos and ticks problem as my children and pets are always in the garden, so my friend recommended me to this company, they shared a lot of information and insight and the process was easy to follow.
