State Extension Services Directory

University Extension Services are among the most trusted sources of pest control, gardening, agriculture, forestry, and Integrated Pest Management (IPM) information in the United States. These organizations are typically affiliated with land-grant universities and provide research-based guidance to homeowners, farmers, landscapers, businesses, and pest management professionals.
