To eliminate cockroaches, we must first ensure environmental sanitation, clean up in time, including toilets and sewers, and clean up garbage in time. Don't leave a sanitary corner at home, don't put food in the open air in the kitchen, don't leave stagnant water at home, and block the gap in time to prevent cockroaches from breeding. Check carefully, even the old computer case. People living in a building had better act in unison, so that cockroaches have nowhere to hide.

The natural enemies of cockroaches are spiders, scorpions, centipedes, ants, toads, lizards and geckos. There is a bird, commonly known as Cucarachero (scientific name Troglodytes audax), which also preys on cockroaches. In addition, cats, monkeys and rats also prey on cockroaches, which are their natural enemies. Biological control is the most effective way to kill cockroaches.
