Why Rodent Issues Become Problematic Within And Around Homes Following Storms
According to University entomologists and experts with the Centers for Disease Control and Prevention, rodent pest issues increase in and around homes after heavy storms, particularly during flash floods and following hurricanes. During heavy rainstorms, water pools around rodent nests and ground burrows in the natural environment, prompting the pests to move to higher ground. The ground surrounding most homes slopes downward from foundations in order to prevent rainwater from flooding into basements and crawl spaces. Therefore, it is no surprise that rodents often invade homes in order to escape rainwater. Crawl spaces, garages, sheds and even vehicles provide rodents with adequate shelter during typical rainstorms, but the pests tend to seek shelter in the upper levels of structures during particularly heavy bouts of rainfall that result in flash floods. Attic spaces are most ideal for rodents during heavy bouts of rainfall, and once they gain access to a home’s foundation, pests are easily able to travel upwards through wall voids in order to secure shelter within attics.
The abundance of tree branches and other forms of plant matter that can be seen littering the ground in residential areas following storms provide rodents with ideal nesting sites in close proximity to homes. Once rodents establish a nesting site on a property, they are reluctant to give it up. Also, violent storms may pull weak and/or dead trees out of the ground, leaving behind a natural burrow where rodents can make themselves at home on a property. Strong winds and flowing water may knock foundation screens loose, allowing rodents access into a structure, and structural damage caused by storms may create easily accessible exterior entry points into wall voids and other concealed indoor areas. Norway rats will not always wait for storm damage to create entry points into houses, as the rats often chew through siding, plaster and insulation in a frantic effort to secure warm and dry shelter during life-threatening storms. Once a storm has ended, homeowners should remove all debris from their yards and seal or patch any exterior structural damage that can provide rats access into homes.
