Hot Shot MaxAttrax Roach Bait kills both large and small roaches and they eggs they carry. The attractant draws roaches to the bait stations, then the roaches eat the bait and crawl away to die. This product contains 12 child-resistant bait stations, with each bait station lasting up to 6 months. Hot Shot MaxAttrax Roach Bait starts killing in hours! Break bait stations apart from each other, then place in areas where roaches have been seen or in out-of-the-way places near walls, in cabinets, under sinks and refrigerators and in closets. Replace baits every six months for continued control or sooner if infestation is heavy.
