The Combat Max 12 Month Roach Killing Bait is designed to effectively control roach infestations with its quick kill formula. The active ingredient, Fipronil, is known for its potency in exterminating roaches.

The product is user-friendly with child-resistant bait stations, making it safe to use in homes with children and pets. There are no messy applications, vapors, fumes, or odors, contributing to an easy and hassle-free experience. These bait stations are ready to use out of the box and can be conveniently placed in various locations around the house where roaches are commonly found, such as near doors, windows, baseboards, pet food storage, and inside cabinets and drawers.

The product offers continuous protection for up to 12 months, which is excellent for long-term roach control.
