Maxforce FC Magnum is the newest and fastest-acting roach bait ever by Maxforce. With Maxforce Magnum you get five times the fipronil, plus a new technology called ContactX(TM) which kills roaches by contact as well as ingestion. That combined with Maxforce Magnum's irresistible formulation attracts even the most finicky roaches, and you've got the next generation in roach killer bait gel. Maxforce FC Magnum comes in a 33-gram syringe, with 10% more bait than other bait gels that only come in 30-gram sizes. Whether roaches eat it, touch it, or share it, Maxforce Magnum kills more roaches faster than any other Maxforce product.
