Pest Management

We are charged with the responsibility of managing nuisance pests of agriculture and human health. Many of these pests are recently introduced species that have become established despite the best efforts to keep them out. These include common pests such as ground squirrels, voles, gophers, and noxious invasive weeds that can be serious pests of agriculture and urban areas alike. We also conduct programs to establish and distribute biological controls for troublesome pests. There have been successful efforts to distribute tiny wasps to control Ash White Fly, and continuing efforts to control Yellow Starthistle, puncture vine, and Lerp Psyllid through the distribution of bio-control agents

Ground Squirrel Control: 

We also assist in controlling the population of those pests already present by: providing expertise and materials to producers and homeowners for the control of certain vertebrate pests which are causing damage; and identifying common pests for producers and homeowners.

Wildlife Services:

The mission of USDA APHIS Wildlife Services (WS) is to provide Federal leadership and expertise to resolve wildlife conflicts to allow people and wildlife to coexist. WS conducts program delivery, research, and other activities through its Regional and State Offices, the National Wildlife Research Center (NWRC) and its Field Stations, as well as through its National Programs. Program biologists apply the integrated wildlife damage management approach to provide technical assistance and direct management operations in response to requests for assistance. WS NWRC research scientists are dedicated to the development of wildlife damage management methods. The Program's efforts help people resolve wildlife damage to a wide variety of resources and to reduce threats to human health and safety. Funding for the WS Program is a combination of federal appropriations and cooperator-provided funds. Wildlife Services conducts its activities pursuant to Memoranda of Understanding, other agreements and legal authorities, and conducts environmental review processes to comply with the National Environmental Policy Act (NEPA).
