For my friends not in the pest management industry, I wanted to write you an important note in case you were wondering why pest management companies are considered essential services. There are many reasons, but I want to tell you about one that specifically relates to COVID-19.

Not only do pest management professionals (PMPs) protect public health by controlling mosquitoes, ticks and other arthropods that spread disease, they actually help considerably to reduce the incidence of a condition that has been listed as a risk factor for severe cases of COVID-19. What’s the risk factor? Read on.
You probably know that domestic cockroaches are filthy. In fact, they are known to carry a number of bacterial, fungal and parasitic pathogens including E. coli, Candida sp., Salmonella sp., and Shigella dysenteriae. They can spread these as they travel from areas with waste or mold to areas of food preparation, or on to food itself. But that’s not the extent of their impact on human health. Cockroaches are known to enter and become lodged in human ear canals. Recent research also suggests that cockroaches may contribute to an increase in glaucoma risk. But there’s also a COVID-19 risk factor that cockroaches play a key role in: asthma.
Over 26 million people in the US, or about 1 out of every 12, suffer from asthma (CDC, 2016). For decades it has been established that exposure to cockroach allergens is a risk factor for developing the disease. It has also been widely demonstrated that exposure to cockroach allergens can trigger asthma attacks in many people with the condition.
A 2013 medical practice parameter from the Journal of Allergy and Clinical Immunology recommends that exposure to cockroach allergens be minimized to reduce the risk of cockroach sensitization and to reduce the risk of asthma morbidity in sensitized individuals. Furthermore, it recommends the use of Integrated pest management (IPM) to eliminate cockroach infestations and reduce exposure. Several studies have confirmed that intervention can reduce concentrations of cockroach allergens, and lead to better health outcomes.
Given the right conditions, and without proper pest management, the German cockroach can go from a small population to hundreds of thousands in a relatively short period of time. This would be disastrous for many people.
So when you see a PMP (if you’re out shopping or exercising), give them a wave or tell them (from 6 feet away or more) thanks for doing their job protecting the public health.
