Weather Impact

Demand for mosquito control services was high last year.

Most PMPs (60%) said the number of requests for these services increased significantly or somewhat at their locations, found the 2026 PCT State of the Mosquito Control Market survey.

In follow-up interviews, PMPs said weather played a role in the severity of mosquito outbreaks. Conducive conditions caused more customers to call for service. Mosquitoes need moisture and warm temperatures for eggs to hatch. And in many parts of the country, conditions were ideal for the pests to reproduce.

That included South Florida. “As hot and humid as it is, it is very good for mosquitoes. And then with the rainfall and all the inter-tidal areas we have being a peninsular state, we have a lot of [pest pressures] going against us,” said Ben Gillenwaters, Hulett Environmental Services.

Big storms moving up the East Coast, including a hurricane last year, caused mosquito populations to grow in and around Augusta, Ga.

The pressure spikes after big storms, said Mike Rogers, Kathleen’s Lawn & Shrub Pest Control.

“We had to deal with the white-footed mosquitoes that came in from Savannah,” he said. “We normally don’t have those in our area, but the hurricane blew them up here.”

Different or invasive mosquito species are a concern for 52% of PMPs, who worry about them becoming established in their markets.

Due to storms, Rogers had to reschedule and add service visits to some accounts. Still, the wetter-than-normal conditions made for “a good year overall” for mosquito revenue.

Wind affects mosquito pressure in Hawaii.

“We have a constant trade wind. It’s pretty steady from the same direction and speed, and as long as those trade winds are blowing, you mostly don’t notice the mosquitoes,” unless you’re in a swampy area or wooded valley, said Steve Russo, branch manager, Sandwich Isle Pest Solutions, a Rentokil Terminix company in Honolulu.

“But when you get the weather change, the different winds shove the mosquitoes up and towards your home,” he said.

Mosquitoes are more noticeable in fall and winter when the trade winds are replaced by Kona conditions. This is when the wind switches direction and blows from the South, bringing warm, humid air, said Russo.
