Horse flies, black flies, fruit flies...there are many varieties of flies in the world, some of which bite, all of which are annoying when found in the home or swarming around your horses or other pets. While bombs and other fumigation methods kill flies as well as any other insects in your home, these strong chemicals also coat nearly everything in your home or barn. Try safer, yet very effective methods of fly control, such as fly traps and tape. Remove wet areas around your home and yard, such as around sump pumps, which serve as fly breeding grounds.
Purchase fly tape that contains pheromones, or sex hormones. Such tape is usually sold in rolls and can be purchased online or through home and garden supply stores or retail stores. The pheromones attract the flies to the tape, to which they subsequently stick and are unable to break free.
Hang the tape in high-traffic fly areas, including barns. The number of tape strips you are hanging up depends on the severity of the fly infestation.
Place additional fly traps around high-traffic fly areas if needed, such as glue board traps that also emit pheromones. Such traps feature UV lights, which attract flies in addition to the hormone scents. Flies fly into the traps, are stunned by a low-voltage grid within the trap and subsequent fall into a glue board, rendering them incapable of escape.
Release predator insects into barn and shed areas affected by flies, such as parasitic wasps, which feed on fly eggs as well as fly maggots.
