What formulation is least used for cockroach control?

Traps are less commonly used for cockroach control compared to sprays, dusts, and baits. While traps can help in monitoring and capturing cockroaches, they are not as effective for active infestation control as other methods.

Sprays provide immediate knockdown of crawling insects and are useful for quick population reductions. Dusts can penetrate cracks and crevices, delivering long-lasting residual control. Baits, which contain attractants that lure cockroaches to toxic substances, allow for maintenance of control over a longer period since they target the cockroaches' feeding behavior.

In contrast, traps mainly serve as a detection tool rather than an effective means of managing a significant cockroach population. They do not address the underlying infestation but rather capture a few individuals that come into contact with them, making them less utilized as a primary method for control.
