The 2nd Civil Engineer Squadron pest management uses a variety of pesticides to control populations of rodents, insects and other nuisance animals at Barksdale Air Force Base, La., Nov. 30, 2017. A lot of effort also goes into the control of these pesticides when they are used to reduce any negative results such as pollution or wrongful termination of other animals.
