The Nattaro Scout Monitor is a bed bug detection trap which holds the Nattaro Scout Lure (sold separately). The Lure contains a unique blend of bed bug aggregation pheromones which draw both sexes as well as nymphs and adults to the trap. Once inside, the bed bugs cannot climb out. The detection trap is designed to be used for early detection of a bed bug infestation and to verify a successful result following a bed bug treatment. Can be placed on the floor, inside furniture and storage areas as well as between the mattress and box spring. The Lure should be replaced every 21 days.
