It is important to put the right type of trap in the right location. This might be the biggest mistake retailers and misinformed customers make. It can be a whopper of a mistake too. Place the wrong trap in the wrong place and you’ll catch nothing or bring every fly in the area to your barn.
Put Sticky Traps where you see flies. Flies are visually attracted to these traps so put them in areas with light, not the darkest part of a barn. Because House Flies generally rest higher up where it’s warmer, put Sticky Traps up high, above your critter’s reach. Sticky Traps are good for inside the barn because they’ll get the flies that are already there, but not bring more in. Sticky Traps work exactly how their name implies. They’re sticky so flies (and other not so lucky bugs) land on the trap they are stuck and can’t fly away.Odor TrapsOdor Traps lure and catch House Flies (but not Stable Flies) from a wide area. You never want to put Odor Traps in your barn or by your back door as you’ll draw all the files in the neighborhood to exactly where you don’t want them. The exception is if you’re drowning in gazillions of flies, then put Odor Traps where you see the flies, but only initially, to bring the population down. Then move the trap away from the barn to draw flies elsewhere. Unlike what you may have heard, you never, ever want to put these on or by your picnic table. Putting Odor Traps there is like inviting all the neighborhood flies to the party too.
