Fluid Refill for Big Stinky. Fluid is combined with a bit of lean meat or fish to activate the attractant. Flies enter and cannot find their way out and the trap quickly fills with a concoction that many users have found to be a great fertilizer. Use outdoors around patios, restaurants, recreation areas, kennels, stables and barns. When used with a sugary liquid, the trap will control wasps as well.

Big Stinky Fly Trap comes boxed, complete with instructions and 6 oz. bottle.
