(NBC) - The official start of summer is just a few weeks away, which also means another season is beginning: mosquito season.
Experts say it's not the sun that brings these pesky bugs to life, but the rain.
How much time will you spend slapping, swatting, and spraying mosquitoes away this summer?
The pest control company Orkin recently ranked the Top 20 Mosquito Cities based on the number of mosquito treatment requests they got in 2013.
More rain means more mosquitoes, because the bugs like to breed in standing water. When experts studied cases of West Nile Virus, a potentially severe illness spread by mosquitoes, they found a certain area of the country tends to have the most cases.
Experts are quick to say it's impossible to predict how severe West Nile season will be, but they are predicting a new virus will make an appearance within the next two years.
Chikungunya was detected in the St. Martin in December. It was the first time it had been found in the western hemisphere. Now several Caribbean countries have reported cases.
You can lower your risk for mosquito bites by wearing a bug repellent that contains DEET, by staying inside during dusk and dawn, by wearing loose pants and long sleeves, and by eliminating all areas of standing water outside your home.
