Rodents are No Small Problem 

Rodents are one of the most widespread pests, infesting approximately 21 million U.S. homes each winter. These potential intruders may be small in size, but they can pose big problems once inside. While most homeowners might be generally familiar with rats and mice, people usually don’t understand or realize the dangerous impacts they can have on our wellbeing and homes until it is too late.

Their long, flexible and cylindrical body shape allows them to fit through tiny cracks and crevices. In fact, rats can maneuver through holes as small as a quarter and mice can squeeze through openings the size of a dime.
