Fly Parasites

Nasonia Vitripennis (Nv)

Controls all types of flies that live in garbage, manure, or compost piles
 

ADDITIONAL INFORMATION:

Fly parasites are tiny wasps which attack several species of filth breeding flies commonly associated with livestock and garbage. Fly parasites attack immature fly pupue, killing them while they are immoble and helpless. Flies have very simple life cycle with a fast maturity rate. the adult female lays eggs which almost immediately hatch into larvae (maggots). After three or four days, these evolve into pupal shell, and this is where the fly parasites do their feeding.
It is also how the parasites are shipped.

Fly parasites live entirely within the manure, never becoming pests themselves. One must look closely in order to see them at all, and most of their activity occurs at night.
 

Release Rates: Aproximately 1,000 fly parasites per 100 sq. ft.
Large Animals: (horses and cattle) approximately 1,000 per head
Medium Animals: (pigs and sheep) 500 per head
Poultry: use approximately 10 per head

N. vitripennis attacks fly pupae and lays several Nv eggs within each one. The number of eggs vary according to the size of fly pupae, which averages about 5 to 7 eggs per host. Nv prefers moist habitats and is well adapted to poultry manure, wet hay or feeds, and garbage situations. It is less effective in very hot and dry areas, or in breeding areas that receive intense sunlight.
Nv are sold in colonies of 10,000 parasitized house fly pupae.
Yield: 50,000 + fly parasites.
