Attractant Traps

There are innumerable different traps available on the market. The key point to understand is that there are different traps for different species of flies. There is no one trap that catches all species. Most of the traps sold in feed, farm and hardware stores are for House Flies as they are the most common pest fly. Many can have an effective attracting radius of about 100-150 feet. Trap placement is important. If the farm has a small or moderate fly problem, traps placed close to the home or in the barn can attract flies from all over the area and make the problem worse. Attractant traps will not catch Fly Predators or other beneficials.

Sticky Fly Traps and Tapes

Most Sticky Fly Traps, tapes and paper, unlike Attractant Traps, can be hung in barns as they do not draw House Flies from afar. Put Sticky Trap in a barn locating them in areas with sunlight, not in dark areas and down low. The exception would be when placing them directly over your cows in a milk parlor or walkway.

Stable Fly Traps

If you want to catch these bad boys you need Stable Fly traps. Fly Predators will control Stable Flies, but you need to put them where Stable Flies reproduce, see page 11. Starbar offers the Bite-Free Stable Fly Trap™ which is available in feed stores. Unlike House Fly traps, which use smell to attract the flies, Stable Fly traps attract their target by visual means. So place these traps at least 10ft. outside of your barn, in sunny areas, where they can be seen by the flies. Stable Flies stay near the ground so put traps low, approximately 2 to 3 ft. high.

Poison Fly Baits

If you are not averse to or prevented from using poison fly baits, they can be effective and are a far preferred alternative to area aerosol pesticide spraying when using Fly Predators.

This is because the attractants in fly bait do not interest either Fly Predators or any of the other beneficials whereas most sprays are indiscriminate and kill all the good beneficials more effectively than the pest flies. This will make your fly problem worse in a few weeks. Normally baits will only be needed to quickly reduce an existing House Fly population if starting a beneficial program late, or if extra control is needed for an outbreak of adult flies due to weather or other temporary factors.

Your vet, local feed store or county AG advisor is the best source of information for what baits are effective now in your area. Understand that flies quickly develop pesticide resistance so “old favorites” may not be as effective as newer products. ALWAYS read and carefully follow the instructions.
