8 Most Prevalent Mosquito Breeds in Texas

According to the Agriculture and safety Unit of Texas, about 85 mosquito species are identified in the state. The common types that you most likely encounter are:

1. Yellow fever mosquito (Aedes Aegypti)

These mosquitoes usually reside along the Texas coasts, notably in the metro area of Houston, and take refuge in homes, imposing the danger of disease transmission to humans. They’re petite insects with black bodies and white-banded legs, and white patches in the center of their bodies when fully matured. These mosquitoes are ideal vectors and transmitters of the deadly Zika Virus and dengue fever and can cause skin irritations when they bite. While in homes, they breed in canvas sheets, flower pot trays and vases, and pails. They bite during the day and only appear in well-lit areas during the night. The Green Mosquito is used to combat this.

2. Asian tiger mosquito (Aedes Albopictus)

Also dubbed the ‘forest mosquitoes,’ these breeds aren’t endemic to Texas since it originates from Southeast Asia. However, they’ve established considerable populations in central Texas, in regions spanning across Austin, San Antonio, and some parts of Dallas. When fully grown, their white single white stipe shows from the head to the back. These mosquitoes carry and transmit disease viruses, including Zika virus, West Nile, Dengue fever, and Chikungunya, deadly to humans. They refuge inside artificial containers and tall grass where they breed and multiply before invading homes as the female anopheles seek to suck blood during the daytime.


3. Southern mosquito (Culex quinquefasciatus)

This mosquito, also known as Culex fatigans, is found in almost every part of Texas, with high concentrations in the southern parts of San Antonio and Bowmansville. They are also in large numbers in the southeastern sides of the state; in Pine Springs, San Angelo, and Alpine. In their adult phase, these mosquitoes have brown bodies, with their tarsi having a darker shade of their body color and their heads being lighter brown. Southern mosquitoes are also notorious carriers of the West Nile and St. Louis Encephalitis viruses which are detrimental to humans and other mammals. Like the rest of the breeds found in homesteads, these mosquitoes also find refuge in tall grass and plants but breed inside artificial containers with water up to one-inch depth. These mosquitoes prefer hunting for blood during the night to nourish their eggs.


4. House mosquito (Culex pipiens)

These mosquitoes are unwanted companions present in Texas homes throughout their lifespan and are a nuisance due to their loud and perturbing buzzes. In Texas state, these mosquitoes are distributed through the northeastern zones of FT. Worth and Dallas, with less concentration in the south part of the state. Mature house mosquitoes can be challenging to differentiate from the southern mosquito since they also have brown bodies and transmit similar diseases. However, their crucial variation is their buzzing sound, which is louder and disturbing for house mosquitoes. House mosquitoes live in homes and perch on walls and darker surfaces or shaded areas during the day and come out in the night to look for blood.


5. Dark rice field mosquito (Psorophora columbiae)

These mosquitoes prefer sucking blood from animals rather than humans and are common in the Texas state countrysides, with vast pasturelands and livestock. Their superb flying prowess suits their long-distance travels across regions of vast pastures as they look for breeding grounds. They’re typically large and have dark and silver-colored bodies with long striped legs and more rigid probes for piercing through hides. Dark rice field mosquitoes are notorious vectors for Encephalitis and breed in waterlogged rice fields and flood lands covered with grass. Since females only seek blood to nourish their eggs, they prefer feeding on nectar from small grass flowers. Their active feeding time is usually throughout the day and fancy sucking blood during the early mornings and late afternoon.


6. Upland floodwater mosquito (Aedes vexans)

Upland floodwater mosquitoes are common in the United States and are found in the Texas state in considerable numbers. They’re endemic to the state and are hugely concentrated in the northern and southeast sides in Elpaso and Marfa, as well as north Amarillo and Childress. Generally, they have brown bodies with lighter and stripped abdomens, especially in the underbelly. The vector Dog Heartworm pathogens are a subsequent cause of the disease responsible for heart failure, severe lung diseases, and death in cats, dogs, and other pets. An excellent breeding ground and habitat for these mosquitoes are roadside ditches and makeshift rain-filled pools and peek noses in homesteads to suck blood from people and animals.


7. Western encephalitis mosquito (Culex Tarsalis)

The Western Encephalitis mosquitoes are typical to Texas’s southwestern to southern coasts in Van Horn, Langtry, Uvalde, Laredo, and Bowmansville. They are typically small with a distinguishable white banded proboscis and black bodies. These mosquitoes transmit the most disease as their counterparts making, them the most hazardous. There are ideal vectors for the West Nile Virus, the St Louis Encephalitis, and the Western Equine Encephalitis diseases that impose threats to humans. The mosquitoes are also abled flyers and can move up to 10 miles from their breeding grounds. They are night feeders and are active within a few hours after sunset, where they feast on blood from birds and other mammals.


8. Eastern saltmarsh mosquito (Aedes sollicitans)

Eastern salt marsh mosquito breeds are medium-sized and located in most parts of the southwestern and southeastern coasts of the state. They also traverse the remote areas of the northern state but are mildly available in the Northeastern parts of Texas.

These mosquitoes have a golden-colored upper side of their thoraces and banded legs. They also are notorious vectors for Dog heartworm disease and the Eastern Equine Encephalitis that are harmful to humans and most mammal pets. These mosquitoes prefer biting and sucking blood from most mammals at twilight but are nagging day biters as well.


Texas is among the states in the United States with the most breeds of mosquitoes responsible for the most threatening diseases. These large numbers are because of the constant rainy weather that creates stagnant water while filling empty artificial containers creating their ideal habitats.
