Combat Source Max Small Roach Bait Kill Max includes a case of 12 child-resistant bait stations designed to control German roaches and other small roaches. Each bait contains food attractants combined with the insecticide Fipronil, which begins killing roaches within hours. The bait stations target the nest by allowing roaches to consume and share the bait, eliminating the colony. These easy-to-use stations require no activation, produce no vapor, fumes, or odor, and provide up to six months of effective roach control. The product is suitable for use anywhere roaches are present.
