Dry Systems Feeders  Feed spillage Design, operate, and maintain feed systems (e.g., bunkers and troughs) to minimize the accumulation of decaying wastage Clean up spillage on a routine basis (e.g., 7- to 10-day interval during summer; 15- to 30-day interval during winter) X X AMIC – November 11, 1996, page 2 Insect Control Checklist for Animal Operations Source Cause BMPs to Control Insects Site Specific Practices Feed storage  Accumulations of feed residues Reduce moisture accumulation within and around immediate perimeter of feed storage areas by ensuring drainage is away from site and/or providing adequate containment (e.g., covered bin for brewer’s grain and similar high moisture grain products) Inspect for and remove or break up accumulated solids in filter strips around feed storage as needed Animal holding areas  Accumulations of animal wastes and feed wastage Eliminate low areas that trap moisture along fences and other locations where waste accumulates and disturbance by animals is minimal Maintain fence rows and filter strips around animal holding areas to minimize accumulations of wastes (i.e., inspect for and remove or break up accumulated solids as needed) Dry manure handling systems  Accumulations of animal wastes Remove spillage on a routine basis (e.g., 7- to 10- day interval during summer; 15- to 30-day interval during winter) where manure is loaded for land application or disposal Provide for adequate drainage around manure stockpiles Inspect for and remove or break up accumulated wastes in filter strips around stockpiles and manure handling areas as needed For more information contact: Cooperative Extension Service, Department of Entomology, Box 7613, North Carolina State University, Raleigh, NC 27695-7613.
