While roof rats are usually only found along the coast of Washington, exterminators are seeing an increase of reported sightings in other parts of the state, local news source Yakima Herald reports.
Officials have yet to determine whether the increase in roof rat calls pest management professionals are receiving is caused by a species population growth or migration. Despite the cause, the rodents are resulting in problems for homeowners throughout the area and an increase in calls to pest control professionals.
Roof rats are named after their tendency to dwell in structure attics, trees and vine-covered fences, the Internet Center for Wildlife Damage Management (ICWDM) states. These pests often enter buildings through roof openings and from overhead utility lines and nearby trees. Roof rats can be extremely troublesome for homeowners as they can gnaw through insulation and wiring, which can result in costly damage and potential health hazards for a family experiencing an invasion.
Preventing an infestation
To avoid luring roof rats into a home, residents can take precautionary measures to pest-proof their property. Because roof rats often eat the pulp of oranges, it's a good idea to clean up any fruit that may have fallen from yard trees. Residents should also trim branches near structures and eliminate brush on their property to eliminate hiding places and routes into the home.
These rats are attracted by water and materials that can be used to build nests. It's therefore a good idea to eliminate moisture and potential harborage throughout the home. Those homeowners who suspect the pests may have gotten into their homes are advised to contact rodent control specialists who can ensure the problem is taken care of promptly.
