What is the recommended action after identifying the location of cockroach harborages?

Placing baits directly into the harborages is a highly effective strategy for managing a cockroach infestation. Cockroaches tend to hide in dark, damp areas, which are their preferred habitats, known as harborages. By placing baits in these locations, you target the cockroaches where they are most likely to encounter the bait.

Baits typically contain an insecticide combined with an attractant that lures the cockroaches in. Once they consume the bait, they will be eliminated, and because cockroaches often return to their harborages, placing the bait where they reside increases the chances of effectively controlling the population. This method not only addresses the immediate issue of visible cockroaches but also helps minimize the likelihood of the infestation spreading.

Addressing the other options: Ignoring the harborages would allow the infestation to persist and worsen. While removing potential food sources is important for overall pest management, it is primarily a preventative measure rather than a direct action against existing infestations. Applying a broad-spectrum pesticide might affect a larger area but lacks the targeted efficacy that baiting does when used in conjunction with identifying specific harborages. Therefore, implementing baits directly into the harborages is aligned with best practices for effective cockroach control.
