Thermacell Repellent's Fourth of July 2022 mosquito forecast calls for some areas to have extreme mosquito activity.Thermacell

Family and friends are not likely to be the only guests at Fourth of July weekend activities.

Make sure you have insect repellent handy because there also will be lots of mosquitos, according to Thermacell Repellents.

Thermacell Repellents says as heat and humidity increase so does the mosquito population.

“The second half of summer will likely be hotter than average for much of the central United States,” said Dr. Benjamin McMillan, senior biologist at Thermacell Repellents, Inc.

Thermacell said, “On the Atlantic side of the country, warm air from the central United States will push into cool air closer to the coast, resulting in increased humidity and rainfall.”

“These large-scale shifts in regional weather will support larger mosquito populations in areas where rain follows hot weather,” McMillan said. “Mosquitoes will come out of hiding when the humidity increases. Watch for mosquito populations to explode once rain brings relief to areas in need of a good soak!”

Working with meteorologists, entomologists, and forecasting data from AccuWeather.com, Thermacell said it uses a mosquito pressure index that predicts mosquito activity. The index ranks mosquito pressure on a 1-to-10 scale, with one indicating moderate pressure and 10 indicating extremely high pressure.

Thermacell is predicting extreme levels of mosquito activity for these 10 metropolitan areas for the holiday weekend:

“Key environmental factors for forecasting mosquito activity are precipitation and temperature. Rainfall and flooding stimulate the development of the eggs of many mosquito species. At the same time, warmer temperatures speed up the time it takes mosquitoes to become adults,” Thermacell said.

Thermacell “uses heat to diffuse highly effective repellent into the air creating a zone of mosquito protection. This zone creates an invisible, scent-free barrier to keep mosquitoes away up to 20-feet from the repeller so you can enjoy the first weekend of summer without mosquitoes.”

Fourth of July 2022 cookout will cost more than it did last year, farm bureau says.

Despite high gas prices, travel by car for the Fourth of July expected to break records, AAA says.
