What is a culex mosquito?
Scientific Name(s)
- Culex pipiens (Northern House Mosquito)
- Aedes aegypti (Yellow Fever Mosquito)
- Anopheles species (Malaria Mosquito)
Description
Mosquitoes are one of the most bothersome summertime pests. There are over 3,000 types of mosquitoes in the world, and at least 170 of them can be found in North America. Out of these thousands of mosquito species, only a couple are known to feed on human blood, including the Culex genus. This genus of mosquitoes (sometimes referred to as common house mosquitoes) encompasses several species which are capable of transmitting diseases such as West Nile virus and Japanese encephalitis.
Habitats
- Stagnant water sources (puddles, ponds, bird baths, clogged gutters)
- Damp areas around vegetation and trees
- Near lakes, rivers, and marshes
- Areas with poor drainage around residential or commercial properties
Behavior & Characteristics
- Active mainly during dawn and dusk
- Males feed on nectar, while females require blood for reproduction
- Mosquitoes are attracted to carbon dioxide, body heat, and certain scents
- Mosquitoes breed in standing water, laying their eggs on the water’s surface
- Mosquitoes can fly several miles in search of food and water sources
Health Risks
- Mosquitoes can transmit diseases such as malaria, Zika virus, West Nile virus, and dengue fever
- Their bites cause itching and swelling, potentially leading to skin infections

FAQs
Q1: Why do mosquitoes bite me?
Mosquitoes bite to obtain blood, which provides the necessary proteins for laying eggs. They are attracted to the carbon dioxide we exhale, body heat, and specific odors emitted by our skin.
Q2: Are mosquitoes dangerous?
Yes. Mosquitoes can transmit diseases such as malaria, Zika, dengue, and West Nile virus, which pose serious health risks, especially in areas with large populations of mosquitoes.
Q3: How can I prevent mosquitoes from breeding around my home?
To prevent mosquito breeding, eliminate stagnant water sources around your property, such as in bird baths, puddles, and clogged gutters. Regularly clean and maintain outdoor spaces to discourage mosquitoes from settling.

What do mosquitoes look like?
Culex mosquitoes can vary in color, typically appearing gray with white, silver, green or iridescent blue scales. They have two wings, a set of antennae, slender bodies and long legs. Culex mosquitoes are usually about 1/4 inch to 3/8 inch in length, although their body size can slightly differ depending on how recently they’ve fed. Individually, mosquitoes are very difficult to spot as they fly because of their small size and due to the fact that they are most active at dawn and dusk. Information Credit: pestworld.org
