RAID DOUBLE CONTROL SMALL ROACH BAITS PLUS EGG STOPPERS roaches are tough to control because they reproduce so quickly—one roach can lay 40 eggs at a time. Raid Double Control Small Roach Baits Plus Egg Stoppers stop roaches from reproducing to break the roach life cycle. One to two weeks after application, you will begin to see roaches with crinkled wings, showing the initial effects of the Egg Stoppers. Roaches do not have to come into direct contact with the Egg Stoppers to become affected—the unique egg stop system penetrates to areas where roaches hide, controlling cockroach populations over time.
