Cockroaches: the creatures that give everyone the creeps. As the weather warms up in 2026, these pests become increasingly active. It is often said that if you see one cockroach, there are likely a hundred more hidden away. To win the battle and eliminate them from your home, you need to act fast.

The most famous cockroach insecticide in Japan is “COMBAT.” Produced by KINCHO, a leading manufacturer of insecticides, this product is designed to eliminate entire colonies just by being placed in strategic areas.

ToggleThe “Domino Effect”: Kill the Whole Colony
Unlike traditional sprays or glue traps that only target individual roaches, COMBAT provides a root-cause solution. All you have to do is place it in the area where cockroaches tend to appear. When one cockroach eats the toxic bait in “COMBAT”, it goes back to its nest and dies there. Cockroaches eat the carcasses and feces of other roaches. The residual insecticides contained in the carcass can also kill other cockroaches. It works on eggs that female cockroaches carry, preventing more cockroaches to be born. The domino effect of “COMBAT” lasts for six months to one full year covering an entire season.
COMBAT works on every kind of cockroach in the world
While some believe local pests require local solutions, COMBAT is formulated to be effective against all major cockroach species found worldwide. It even works on “super roaches”—the stubborn, resistant strains that have developed immunity to weaker sprays. Once placed, you can often see results within a single day.
Why you need to act fast?
Most cockroaches cannot survive the winter outdoors, but they thrive and breed rapidly once indoor temperatures rise above 25°C. It is best to exterminate them when their numbers are few. Place COMBAT in early spring, and you won’t have to deal with them when summer arrives!

Highly effective, yet small enough to be hidden anywhere
Place “COMBAT” in every gap including a kitchen cabinet below the sink, behind the fridge, and the TV, under the washing machine, and the porch. You won’t see cockroaches anymore. “COMBAT” is small enough to fit in small gaps.

An enemy of the human race: cockroach. Don’t you want to say goodbye to them forever and start a comfortable life? If you are still annoyed with cockroaches, you should try KINCHO “COMBAT”. If you have any friend or family having trouble with cockroaches, how about buying “COMBAT” as a practical souvenir!
