What are the most widely used formulations for cockroach control?

Baits are the most widely used formulations for cockroach control due to their effectiveness and ease of use. Baits attract cockroaches, which then consume the toxic substance contained within and transfer it back to their nesting sites. This method not only reduces the immediate population of cockroaches but also targets the issue at its source by impacting those individuals in the nest.

Unlike sprays, which may provide immediate knockdown of visible cockroaches but do not guarantee long-term control, baits continue to work over time as cockroaches share the bait with others in their habitat. Traps, while helpful for monitoring and assessing infestations, are not as effective at reducing overall populations. Granules, on the other hand, might not be suitable for cockroaches in their typical environments since they primarily thrive indoors and often avoid areas where granules are used. Therefore, the long-lasting and effective nature of baits makes them the preferred choice in cockroach control strategies.
