Identification
Aedes aegypti mosquitoes are small, measuring about 1/8 inch in length. They have black bodies with distinctive white markings on their legs and a lyre-shaped marking on their thorax. Their wings are clear, and they have long, slender legs adapted for quick movement.
Lifecycle & Reproduction
Aedes aegypti undergo complete metamorphosis, progressing through four stages: egg, larva, pupa, and adult. Females lay eggs in stagnant water, which hatch into larvae within a few days. Larvae develop into pupae before emerging as adults in about 7 to 10 days. Females require a blood meal to produce eggs and can lay hundreds of eggs in their lifetime.
Habits, Diet & Behavior
These mosquitoes are primarily active during the daytime, with peak feeding occurring in the early morning and late afternoon. Females feed on human and animal blood, while males consume nectar. They are known vectors of several diseases, including Zika virus, dengue fever, and yellow fever.
Where You’ll Find Them / Typical Locations
Aedes aegypti mosquitoes prefer warm, humid environments and are commonly found:
- Near standing water in containers, puddles, and clogged drains
- In urban and suburban areas with high human populations
- Inside homes, particularly in shaded, cool areas
- Around potted plants, birdbaths, and neglected swimming pools
- In tropical and subtropical climates
Threats & Danger
Aedes aegypti mosquitoes are primary vectors of serious diseases such as Zika virus, dengue fever, chikungunya, and yellow fever. Their bites cause itching and irritation, and they can quickly multiply in residential areas if water sources are not managed.
Prevention
- Eliminate standing water by regularly emptying containers and drains
- Use insect repellents containing DEET, picaridin, or oil of lemon eucalyptus
- Install window screens and use mosquito nets in sleeping areas
- Wear long sleeves and pants to reduce skin exposure
- Treat outdoor water sources with larvicides to prevent mosquito breeding
Signs of Infestation
- Frequent mosquito bites, particularly during daytime hours
- Presence of small, black mosquitoes with white markings indoors or outdoors
- Larvae or pupae in standing water sources
- Buzzing sounds near water or shaded areas
- Reports of mosquito-borne disease outbreaks in the region
How to Get Rid of It
- Remove standing water and improve drainage around properties
- Use mosquito traps and electric zappers in high-activity areas
- Apply insecticides or natural repellents in breeding zones
- Introduce mosquito-eating fish in ponds and water containers
- Seek professional pest control services if infestation persists
