What’s the Best Way to Kill Cockroaches: Baits & Gels vs. Sprays

Let’s face it: there is nothing more satisfying than spraying a cockroach and watching it writher on the floor in its death throes. Unfortunately, your satisfaction at a single bug’s demise will be fleeting because while you have successfully killed one cockroach, it’s likely that hundreds or even thousands more remain unharmed, ready to propagate and skitter all around your home at night.

For more effective cockroach killing power and control, you need an insecticide that targets cockroaches at their source. Unlike spray insecticides, Combat baits and gels are not contact killers. Instead, Combat is formulated with irresistible attractants disguised by food. Roaches readily ingest Combat and bring it back to the nest where their mucus, feces and carcasses spread the poison, dispatching the entire cockroach infestation in a powerful, exponential domino-like effect.

That brief gap between ingestion and death is important because it gives roaches the time necessary to carry the insecticide back to the nest where it’s spread amongst the rest of the pests.

Spray and aerosol insecticides, on the other hand, are designed to kill on contact. While they provide short-lived satisfaction by killing the cockroaches you see, they do nothing to solve the larger issue of the roaches you don’t. As long as the nest or colony remains intact, your cockroach problem will, too.

Placing Combat baits in multiple locations simultaneously can accelerate overall control. Combat gels are especially well-suited for hard-to-reach areas, such as behind refrigerators or in cracks and crevices where you suspect cockroaches may be entering the home from the outside.

When you compare spray insecticides with Combat baits and gels, you’ll see that the difference comes down to killing a few roaches immediately or completely eliminating the cockroach infestation altogether. If your real goal is to eliminate a cockroach infestation completely, the only way to truly do it is to target cockroaches at their source.
