Mosquitoes by State 2024

Mosquitoes by State 2024

Georgia

Mosquitoes are some of the most common insects, and pests, in the world. Mosquitoes love warm and humid weather, and their bloodsucking abilities are annoying for many travelers throughout the year, regardless of the location. Every year, mosquito repellents are purchased in extremely large quantities, especially for those that are looking to make the trek outdoors for such activities as hiking and fishing. Canoeing is one of the worst activities, as the slower speed when compared to other sports invites mosquitoes.

Atlanta, Georgia is one of the worst cities in the world for mosquitoes and ticks. Those who are looking to visit the state within the summer months are especially susceptible to mosquito attacks. Hiking in short sleeve shirts or short pants almost always results in multiple bites appearing, even if you didn't feel them. Most visitors that wish to visit this place during the summer for more traditional outdoor activities are always warned to come prepared with the proper equipment and repellents. There are advisory tips that help to relieve the bite of a mosquito, including natural home remedies.

Of course, the climate in Atlanta is extremely facilitative to the growth of mosquitoes and their attacks. The warm weather, ample woodland, and humid atmosphere give them a tropical haven to feed on unsuspecting travelers.

Texas

Texas, another state known for being warm and humid, is home to the most species of mosquito. From February to November, eighty-five different species of mosquito can be found across the state. Visitors and residents alike must be prepared with bug spray and protective clothing to combat the vast number of mosquitoes.

Florida

When a person thinks of a warm, humid environment, Florida is probably one of the first states that comes to mind. In southern Florida, mosquito season lasts from February to November. This means that there are only two months out of the year when mosquitoes do not plague the state. With about eighty different species of mosquito in the state, this insect is definitely a nuisance for those in Florida.

Other States With Many Mosquitos

It is no surprise that many of the states with the most species of mosquito are those that border the above three states. Alabama, Louisiana, North Carolina, and Virginia all also have high numbers of mosquito species. These states are generally warm and humid, providing the perfect home for mosquitoes to develop and thrive.

There are some other states that are surprising as home to many species of mosquito. South Dakota, Montana, and Oklahoma all have between 60 and 70 species of mosquitoes. These states do have much shorter peak seasons for mosquitoes, however. Montana’s peak season lasts from May to September while both Oklahoma’s and North Dakota’s begin in April.
