Keep Midge and Filter Flies Under Control with Strike Products

Primarily used in wastewater treatment facilities, Strike products can also be applied in any facility that uses water as part of its process. Midge and filter flies can invade your location if your facility has a water reuse system such as lagoons, lakes, ponds, or retaining basins. Strike products are the perfect, low-maintenance solution to help keep midge and filter flies under control.

Midge vs. Filter Flies

Midge Fly

Midge flies alter water quality, clog pipes, and in extreme cases, transmit pathogens. Adult midge flies resemble mosquitoes in appearance with “bushy” antennae, and are ready to mate and lay eggs within days of emergence.

Filter Fly

Operations also need filter fly control they can count on to combat both the nuisance factor and the potential health risks. Adult filter flies are known for their “hairy” appearance and pointed moth-like wings.
