We would not recommend using Quick Draw Fly Bait near your patio. Quick Draw Fly Bait is something you would use near dumpsters, trash area, barns and other commercial areas. It would most likely bring the flies closer than you like. We recommend using either the Flies Be Gone fly traps or the Advantage Fly traps about 30 feet from the patio. This will help draw the flies to other areas and away from you and your guests. Fly traps should be deployed about a week before the gathering to be effective. Using fans on the patio is also helpful as most flies cannot fly against a wind current and would simply be kept out of the area. Nothing is fool proof when you are dealing with flying insects but the tips and hints we have provided should help tremendously.
