Dr. D.E. Williams of the USDA discovered that biting flies are attracted to sunlight as it shines through a particular translucence of fiberglass. Olson has designed a cylinder using this fiberglass that is coated with a clear sticky substance to create a perfect attractant and trap for the biting fly. The biting flies are attracted to the fiberglass glass but they cannot escape the stickiness.
One trap can catch as many as 5,000 flies! Olson's Biting Fly Trap attracts biting flies, stable flies, black flies, and bottle flies.
Suggested Use:Place anywhere biting flies are a problem - stables, kennels, zoos, compost piles, backyards, swimming pools, golf courses and beaches.
Each package contains the following: 1 fiberglass cylinder, 1 wooden stake, 2 brass fasteners, 2 giant paperclips, 1 sticky sleeve, 1 replacement sleeve and complete instructions.
Simply drive the wooden stake into the ground and place the fiberglass cylinder on the stake. Biting flies will be attracted to the cylinder and stick to the adhesive coating.
