Mosquitoes fill DC, VA, and MD yards every summer. Ever wondered what they actually eat and why they bite? Knowing their diet helps you understand why they show up and how to get rid of them.
In my family’s own backyard, dense shrubs and standing water fed swarms that drove us indoors all season. That hands-on experience shaped how we treat mosquitoes for our customers today.
What Do Adult Mosquitoes Eat?
The answer depends on whether you’re looking at males or females.
Most adult mosquitoes eat nectar from flowers and plant sap for energy. This sugar fuels their flight. Both males and females drink nectar throughout their lives.
Male mosquitoes never bite. They live entirely on plant sugars. They’re harmless to people and animals.
Only female mosquitoes bite people and animals. They need protein from blood to produce eggs. After a blood meal, females lay their eggs in standing water.
Female mosquitoes find hosts by sensing carbon dioxide, body heat, and skin chemicals. Their tube-like mouthpart (proboscis) pierces skin and draws blood.
See our guide on male vs female mosquito differences for more on biting habits.

What Do Mosquito Larvae Eat?
Mosquito larvae live in standing water and feed at the surface. They eat algae, bacteria, and bits of decaying plants. According to Virginia Tech, larvae feed nonstop to fuel their growth. Learn more in our pest library.
Larvae molt four times as they grow. Each stage eats microbes and organic debris from the water. LSU research shows that what larvae eat affects how big the adults get.
During the pupal stage, mosquitoes stop eating entirely. They rest and use up energy stored from their larval phase. Adults come out in a few days.
The Mosquito Life Cycle and Food
The mosquito life cycle has four stages:
- Eggs: Laid on water or damp surfaces. When they hatch, larvae start feeding right away.
- Larvae: Grow in standing water for 4-14 days, eating algae and bacteria.
- Pupae: Don’t eat. They rest for a few days before becoming adults.
- Adults: Must drink sugar (nectar) within a day of emerging to fuel flight. Females then seek blood meals.
Mosquito Species in Our Area
Different species feed and breed in different ways.
Aedes mosquitoes breed in containers and floodwater. Species like Aedes albopictus (Asian tiger mosquito) feed on nectar and bite during the day. Some can carry La Crosse encephalitis.

Culex species breed in polluted, stagnant water. They bite at dusk and are the main carriers of West Nile virus in our region.
Anopheles mosquitoes breed in ponds and wetlands. They bite at dusk and can carry malaria, though this isn’t a risk in our area.
What Affects Mosquito Feeding
Temperature: Mosquitoes are most active between 70-90°F. Below 50°F, most go dormant.
Humidity: High moisture helps mosquitoes avoid drying out. They feed more on humid days.
Wind: Strong wind stops mosquitoes from flying well, which cuts down bites.
Time of day: Many species prefer dawn and dusk. Aedes bite during the day. Culex and Anopheles bite at night.
How Their Diet Shapes Our Treatment
Knowing what mosquitoes eat helps us target treatments at the right life stage.
Larvicides in standing water: Products like Bti kill larvae while they feed. According to the Extension Service, Bti works well around ponds and birdbaths.
Barrier sprays on plants: We spray shrubs and ivy where mosquitoes rest and feed on nectar. When they land on treated leaves, they pick up the product and die. Research on attractive toxic sugar baits shows sugar-based lures can kill adult mosquitoes very effectively.
In2Care system: We use In2Care traps that contaminate adult mosquitoes with larvicide and fungus. They then spread these agents to other breeding sites on their own.

Tips to Reduce Mosquito Bites
A few simple steps make a big difference in how many bites you get.
- Dump standing water weekly: flower pots, birdbaths, gutters, pet bowls
- Mow your lawn and trim dense shrubs where mosquitoes rest
- Wear light clothing and use EPA-registered repellents (DEET, picaridin)
- Stay inside at dawn and dusk when many species are most active
- Fix screens on windows and doors to keep mosquitoes out of your home
Here’s what worked in our own backyard.
Knowing what mosquitoes eat and where they breed helps you target pests with better results. Our pest control services tackle mosquitoes year-round with larvicides, barrier sprays, and In2Care traps across Alexandria, Reston, and Herndon.
