MINNEAPOLIS (AP) — The Minnesota heat may be starting to subside, but a peskier weather-related problem is getting worse — mosquitoes.

The last few months have been good for mosquitoes: moist breeding grounds plus warm temperatures. That's led to about twice the typical mosquito population, at least by one measure.

A sampling of the Metropolitan Mosquito Control District's 134 traps recently found an average of 1,425 adult mosquitoes per trap. The nine-year average for that time of year is 643 mosquitoes per trap.

At the Fish Lake Acres Campground in Prior Lake, manager Tim Orf says the problem is "horrendous."

Jim Stark heads the Mosquito Control District. He says mosquitoes generally live only four to five weeks, but each round of rainfall breeds another round of mosquito families.
