How long does it take for an egg to turn into an adult?

The life cycle of the Aedes aegypti mosquito is only about 10 days. The female mosquito will lay eggs on moist surfaces near water (mostly in areas where people are).  In order to turn into adults, the pupae need water to emerge from their cocoons. Once they emerge, they become adults that look for food sources (namely humans).


What does the full life cycle look like?

Aedes albopictus mosquitoes, also known as the Asian tiger mosquito, are not known to carry the virus. They will feed on humans, but they do not typically live in people's houses like A. Aegypti does. The eggs of this mosquito are laid outside in water containers such as buckets or animal dishes where they can survive for days waiting for hatching. The larva hatch from the eggs, pupate and then emerge as adults to mate and start laying eggs again.


How many eggs do they lay?

After taking a blood meal, female mosquitoes use their proboscis to pierce the skin of their victim. They then inject an anti-coagulant (which is what causes the red bump) as well as an anticoagulant that prevents clotting. Female mosquitoes can lay up to 200 eggs in batches of 50 at one time. Aedes albopictus, another species of mosquito, lays up to 400 eggs at one time.


How hard are they to get rid of?

The Aedes albopictus mosquito is notoriously difficult to control. The reason for this is that they are highly adaptive and can develop resistance to pesticides over time. They also feed on humans, which makes them more likely to be found close to human populations than other species of mosquitoes. For these reasons, the Aedes albopictus mosquito is one of the most important disease vectors in the world.


Where are they most likely to be found?

Aedes aegypti mosquitoes are found in warm climates, such as the southeastern United States. They usually live in humid areas near water sources, but they can also be found in dry areas with standing water. The eggs hatch within 3-5 days if they're placed in moist soil or sand. A mosquito larva has three life stages (larva, pupa, and adult). Larvae feed on algae, bacteria, decaying organic matter, and other microorganisms.


Why should we get rid of them if they kill mosquitoes too?

The Aedes aegypti mosquito is an aggressive, invasive species of mosquito that transmits deadly diseases such as Zika, Dengue fever, Chikungunya, and yellow fever. Although these mosquitoes also prey on other mosquito species that carry similar illnesses, Aedes aegypti plays an important role in the proliferation of these diseases. 

This particular species is known for its rapid population growth due to its ability to successfully adapt to new environments through multiple generations per year.


What happens when you remove them from your property?

Mosquitoes must be eliminated from your property in order to stop the life cycle. Eliminate standing water sources, like old tires or rain barrels, so the eggs cannot hatch. If you have wetlands on your property, consider installing mosquito fish (Gambusia affinis) to help control larvae populations. They breed well in still water and eat mosquito larvae as food.
