flies on cow face

Around Concentrated Animal Feeding areas, major fly breeding/resting areas have a lot to do with EDGES!

  • Fence lines where manure mixed with wet soil accumulates
  • The edge of feeding aprons where moisture and manure accumulate
  •  Edges of potholes, in pen corners, and around gates;
  •  Along pen drainage channels or edges of holding ponds
  • Wet areas around water troughs
  • Underneath feed bunks were stale feed accumulates
  • The bottom side of fence boards
  • In corners of feed bunks where stale feed accumulates
  • Manure accumulation under fences/facilities in corral/animal handling areas
  • Edges of stored manure and silage.
  • Edges around hay storage and damp areas under bales.
  • The edge between dark and light are good resting areas (1/2 way in a barn, underneath fences)

These are places can be a focus of sanitation and/or pesticides. Flies cannot develop in dry materials.

  • Use clean gravel and other fill to eliminate low spots in feedlots and dry lot areas.
  • Proper tiling can reduce wet barnyards.
  • Cut weeds and control excessive plant growth around facilities. This will also reduce odor problems
  • Wet Feeds: Various flies (e.g. stable fly) can develop in plant material, such as old silage in and around feed troughs and trench silos.
  • Don’t provide them crop residues, discarded in piles during and after harvest Spread this material thinly for quick drying.
  • Uneaten hay where animals are fed in the fields provides fly breeding areas.
  • Uneaten grain in or around feed troughs (poor bunk management) or storage bins should be cleaned up on a regular basis.
