Two major changes have occurred in cockroach control since the early 1980s. First, we’ve learned a lot more about the health impacts of cockroaches over the past 25 years. Besides being unsanitary and capable of spreading disease pathogens, we now have solid evidence to show that cockroaches are major contributors to asthma morbidity, especially among children living in infested homes. Second, with the discovery of effective baits, we have much better tools for cockroach control today. The insecticides available to me in 1980 were mostly residual sprays and dusts that had to be applied directly to cockroach hiding places.
Today pest management professionals and even homeowners have access to technologies that are safer and vastly superior to the old insecticides. Although sanitation is still important for cockroach IPM, baits have shown an ability to suppress cockroach numbers even in cluttered and poorly maintained living quarters.
