For convenient and discreet fruit fly trapping, the InVite Fruit Fly Trap is an effective, leave-behind tool — even for difficult-to-control dark-eyed fruit flies and phorid flies. The trap employs a two-part lure system: liquid in the pouch activates the powder pre-loaded in the trap to create an irresistible attractant. It uses a non-toxic, non-pesticidal formula that can be used in food areas. The trap is designed to be placed in any orientation, including upside down on the underside of counters or tables with no spills. A clear backing makes monitoring quick and easy. The trap may be lightly sprayed with a microcap product to kill flies that are attracted but may not enter the trap. InVite Fruit Fly Traps are sold in cases of 12.
