## Overview

Black Flag Flying Insect Killer is a powerful aerosol spray designed to eliminate a wide range of flying insects including houseflies, fruit flies, and mosquitoes. It works instantly on contact and provides up to 12 weeks of residual protection on treated surfaces. Suitable for both indoor and outdoor use, it features a clean scent and can be applied as a surface or space spray, targeting common insect breeding areas for maximum effectiveness.

## Description

Black Flag Flying Insect Killer kills fast – plus, it kills bugs landing on treated surfaces up to 12 weeks (excluding mosquitoes, wasps, hornets and yellowjackets). This formula is effective against houseflies, fruit flies, mosquitoes, wasps, hornets, yellowjackets, gnats, skipper flies and small flying moths and can be used both indoors and outdoors. Contains a clean, fresh scent. Indoors, use as a surface spray on window sills, window and door frames and other indoor surfaces where listed insects may land. You may also use as a space spray: Close all doors and windows, and spray upward into the center of the room with a slow, sweeping motion. For an average room, spray 5 to 10 seconds, moving toward the door. Outdoors, allow the fog to drift over the treatment area. Direct the spray toward bushes or grass from at least 4 to 6 ft away. Pay special attention to breeding areas, like garbage cans and compost piles. For best results, spray when the air is calm and allow a few minutes for the product to take effect.

Review: Highly recommend - Love it. It is the best. It has a less toxic smell and kills really well.
Review: See It Work - Easy to use and you can see dead flies so you know it works perfectly. Make sure if spraying inside to have a window open while applying tho.
