The Centers for Disease Control has provided updated guidance on rodent control, and the latest version cautions that environmental management programs and pest control services may receive reports of “unusual or aggressive rodent behavior” amidst pandemic-related closures.
The new guidance, which has been updated to reflect pandemic closures, warns that rats may be missing out on restaurant scraps and commercial business garbage, causing them to scatter off to new places in search of food.
“Rodents rely on the food and waste generated by these establishments. Community-wide closures have led to a decrease in food available to rodents, especially in dense commercial areas,” said the CDC guidance. “Some jurisdictions have reported an increase in rodent activity as rodents search for new sources of food. Environmental health and rodent control programs may see an increase in service requests related to rodents and reports of unusual or aggressive rodent behavior.”
