Combat® Source Kill vs. Combat® Source Kill Max

Combat Source Kill and Combat Source Kill Max are two different, yet both effective formulations of ant and roach baits. Both of their active ingredients kill ants and roaches at the source—the colony or nest.


Combat® Source Kill


Combat Source Kill is formulated with Hydramethylnon, one of the most thorough active ingredients on the market for ant and roach baits. Hydramethylnon is a slow-acting insect stomach poison that kills ants and roaches after ingestion. This delay allows bugs to deliver the poison back to the colony where it’s spread among the rest of nest killing insects in a domino-like effect, resulting in destruction of the infestation at the source.

When using Combat Source Kill correctly, you will typically begin to see a reduction of ants and roaches after 1-2 weeks. Initially, you will see an increase in ant and roach activity around the bait stations you have placed. This is natural and expected, and is an indication Combat is doing its job.


Combat® Source Kill Max


Combat Source Kill Max, on the other hand, is formulated with Fipronil, one of the fastest active ingredients on the consumer market for ant and roach baits and gels. Unlike Hydramethylnon, Fipronil is an insect nerve poison that kills ants and roaches by contact and ingestion. It starts killing insects within hours, so you begin to see results almost immediately.

Although Fipronil (Combat Source Kill Max) is a faster-acting poison than Hydramethylnon (Combat Source Kill), ants and roaches still have time to spread the poison throughout the rest of the ant colony and roach nest. This is how Combat Source Kill Max targets pests where they live, and eliminates the source of the infestation.

In addition to bait stations, Combat Source Kill Max also comes in gel form that ants and roaches find irresistible. Appearing to pests as an enticingly rich source of food and water, Combat gel is perfect for hard-to-reach areas, as well as cracks and crevices, where ants and roaches enter the house from the outside.
