Attracts house flies with multiple feeding stimulants and a powerful sex pheromone,. Holds 10,000 flies. Can be hung or set on ground outdoors where flies are most active. Disposable. Not for use indoors.
this is what we have found to be the most effective, as well as the least expensive. although the traps come w/pheromones, we don't use them because what we use for bait is so effective.
follow the directions for adding water to the traps, then toss in a couple of raw chicken livers. as the liver decays, the traps become more attractive to the flies. we use hay-string to hang the traps from trees. (in the shade)
the traps are meant to be disposable, but we use each trap for 1-2 seasons before needing replacement. when the trap is full, DH puts on rubber gloves and takes all of the traps to his 'fly pile'. lol (he usually does the fly traps once a week) one at a time, he flushes the traps out clean with a garden hose, then pours salt onto the flies and maggots that have just been flushed out. the live flies are too wet and confused to make an escape, and the salt kills them. he puts the used livers into a zip-lock bag for proper disposal.
once he has all of the traps flushed, he checks the water level, tosses in fresh chicken livers, and rehangs the traps.
controlling the population is easier than killing them after the fact. we always put the traps out before the fly season starts and that seems to limit the problem through the warm months. we place one trap per acre, and two traps near individual livestock areas.
note: use raw CHICKEN LIVERS. we've tried every kind and cut of meat. NOTHING works as well as the chicken livers.
