Fly Parasite Release Station (FPRS)


Helps you get the most out of your fly parasites.

  • Provides protected container for fly parasite wasps to emerge from pupae (they emerge over 3 week period)
  • Protects parasites from being trampled or being eaten by birds scratching in manure
  • Protects parasites for decomposer activity in manure
  • Fly parasites exit through plastic mesh
  • Made of tough plastic mesh which resists weather - sheds water
  • Low risk of animal injury
  • Economical - about $5 each

The release station can be mounted vertically or horizontally using the enclosed wire, plastic strap or screws (not included) out of the reach of animals.


If using screws or nails for mounting (not included), make a keyhole shaped hole in the side of the release station. Push the head of the screw or nail though the larger opening of the release station and lock in place by pulling down on the release station. Pictured are some suggestions for mounting the Fly Parasite Release Station.

Using Release Stations

  1. Place release stations every 50 to 100 feet where fly breeding takes place.
  2. Attach with tape or strap to pole or post, or hang 3 to 5 feet above ground.
  3. Lift lid, place a tablespoon or two of bulk fly parasites into the container each time shipment arrives.
  4. When release station is full, empty it and start over. The release station holds a quart volume.
  5. If ants find the station, coat the post with a 2 inch band of Stikem ant barrier above and below the station.
