Mosquito control in Covington, KY is a summer necessity. The Ohio and Licking rivers, the low ground and river bottoms, and the humid Ohio Valley heat give mosquitoes a long, productive season. Most of the mosquitoes biting you in the yard were not born at the river, though, they came from standing water within a couple hundred feet of your door: a clogged gutter, a saucer under a planter, an old tire, a tarp, a birdbath, a stopped-up alley drain. Asian tiger mosquitoes, the aggressive daytime biters with striped legs, are especially good at breeding in tiny containers around an old city lot. An experienced local exterminator reduces the breeding sites and treats the shaded resting areas where adults wait out the day.
Where the mosquitoes actually come from
Adult mosquitoes rest during the heat of the day in cool, shaded, humid vegetation, under decks, in ivy and dense shrubs, in tall grass along a fence line, and under porches. They breed in standing water, and it takes surprisingly little: a bottle cap's worth for some species, a week for eggs to become biting adults.
That is why a treatment that ignores your gutters, planters, tarps, and the low spot behind the garage will disappoint. The river drives the humidity and the long season; your yard supplies the nursery.
How mosquito treatment works
The exterminator walks the property to find and eliminate or treat breeding sites, then applies a residual barrier treatment to the shaded resting areas, the undersides of leaves, dense shrubs, fence lines, and under decks and porches, where adults spend the day. Where standing water cannot be drained, such as a rain barrel or a low spot, larvicide is used instead.
Because adults keep flying in from the neighborhood, mosquito control works best on a recurring schedule through the season, with the barrier refreshed as it weathers and new breeding sites checked each visit.
