Triangular-Shaped Mouse Bait Station Mouse-size PROTECTA RTU, a staple of the industry since 1991, holds 1 oz., 28g, 20g and 15g BLOX baits. Triangular-shaped with angled entry holes, PROTECTA RTU fits flush against a wall or in a corner where mice travel. Mice do not hesitate to enter and once they’re inside, the station’s interior baffles lead them to the bait. Compact PROTECTA RTU fits in tight baiting places under pallets, in cupboards or behind appliances. It is made of heavy-duty, injection-molded plastic to withstand tough baiting situations. This tamper-resistant bait station automatically locks when closed, keeping bait away from children and non-target animals. Yet, a simple motion with the PROTECTA 2-prong key unlocks the device, reducing service time by as much as 75 percent. Service labels are included in each case. Restrictions: Only 1 key per 12 stations will be shipped, please contact us directly…. Compact PROTECTA RTU measures 5 1/4′ (l) x 1 1/4′ (h) x 3 3/4′ (w).
