BEATING THE BITE: Grand Forks Sprayed for Mosquitoes 50% Less Than in 2010

GRAND FORKS (WDAZ-TV) - There were fewer mosquito slaps this summer. Grand Forks sprayed half as much as it did last year.

It's one good thing that came from spring flooding.

High, fast-moving river water is not ideal for mosquito breeding. And mosquito numbers really never made it to where they have been in past years.

Mosquito Control Supervisor Todd Hanson is wrapping up his busy season, but it hasn't been quite as busy as past years.

The mosquito count on Wednesday was zero.

Hanson says he isn't surprised numbers have dropped off this early because the insects never got a good start.

"It was one of the years where spring flooding in the region was extensive. Grand Forks didn't suffer so much, but there was a lot of runoff. Probably ran off a lot of the flood water eggs," Hanson said.

Hanson says there were a total of nine city-wide sprays. That's half as many as last year.

But crews did do a lot of larviciding. That's where pellets are dropped in catch basins and places where there is standing water to prevent mosquitoes from becoming adults.

"We had areas on the lower trails on the greenway that we just couldn't get to. It was just too wet. And the river coming out of the bank, all that silt. It just didn't dry up," Hanson said.

Hanson says there were only a total of four cases of West Nile virus in humans across the North Dakota. None of the mosquitoes caught in Grand Forks traps this summer tested positive for the virus.

"The weather conditions and the larvaciding that the program is doing, that really kept the numbers downs," Hanson said.
