What two materials are commonly used to treat roaches found in electrical outlets?

The use of dusts and baits is a highly effective strategy in managing roach infestations, especially in hard-to-reach areas like electrical outlets. Dusts are designed to adhere to surfaces and can effectively penetrate cracks and crevices where roaches tend to hide, providing prolonged contact with the insecticide. This ensures that even those roaches that are not actively feeding on bait receive the treatment.

Baits are also essential in this context, as they attract roaches to consume the poison, which then spreads throughout the population when they return to their nests, potentially impacting others that did not directly encounter the bait. This dual approach—using both dusts for immediate control and baits for ongoing management—creates a comprehensive pest management strategy that is particularly suited for the unique challenges presented by electrical outlets, where safety and effectiveness are paramount.

In comparison, the other options may not provide the same effectiveness in this specific scenario, as granules typically require contact with moisture to activate and are less effective in confined areas. Foams and pastes can be good for certain applications, but they may not penetrate as deeply as dusts, and liquid sprays might pose a safety risk when applied near electrical outlets due to the risk of electrical shorts.
