Small mammals pass through or under chain link security fences, triggering sensors and undermining facility infrastructure at sensitive military sites. Traditional methods of rodent control are not practical because of the vastness of land to be maintained with limited manpower. Permanent barriers (above and below ground) and low-maintenance, long-term bait stations offer potential permanent and cost-effective solutions to mitigate rodent intrusions. We assessed Richardson’s ground squirrel populations, activities, and burrows at Malmstrom Air Force Base, MT. We also conducted preliminary barrier trials in the outdoor rodent buildings of the USDA National Wildlife Research Center in Fort Collins, CO. Ground squirrels …

The National Wildlife Research Center (NWRC) and its predecessor laboratories have a long history of developing materials and methods for managing rodents and the damage they cause. The NWRC has been influential in exploring, developing, and maintaining legal uses of many traditional field rodenticides such as strychnine and zinc phosphide. Products have been developed for managing rodents in a variety of locales, and for managing a variety of species, from commensal rodents in urban areas, to pocket gophers and mountain beaver in forests, prairie dogs and ground squirrels on rangelands, and nutria and beaver in wetlands. Considerable research has also …
