Flys Be Gone Trap is a great product to use to deter flyies from your home. Each trap is effective for up to four to six weeks and catches thousands of flies over an area of 50 to 100 yards. You want to place the trap approx 30ft away from the area you are experiencing flies. The bait will draw them away for 4-6 weeks.
