• Distribute the material in heaps near to the places where the flies pupate
• Make sure the material is distributed on dry places or on dry(er) manure
• Place close to concrete or stable edges or in furrows
• If necessary lightly cover the Appiwasp pupae to protect them

Start introduction as soon as flies can be expected during the fly season. If a population peak of flies can be expected, a more frequent introduction may be necessary to ensure a constant release of wasps.

Environmental conditions
Efficacy reduces at low (under 15°C) or high temperatures (higher than 38°C). 

Storage and handling
• Use product upon arrival
• Storage after receipt: max. 5 days
• Storage temperature: 10-15°C/50-60°F
• In the dark

Adults: minute 2 mm black wasp
Other stages: develop inside host 

Mode of action
Female adult parasitic wasp parasitizes the fly pupa. 

Visual effect
When the adult parasitic wasp emerges (within 2-5 days after receipt of the product) from the pupal shells, they will start searching for fly pupae. After parasitism, wasps of the new generation can be expected in approximately 2-3 weeks. 

Parasitic wasps are just one tool in an integrated program to control stable flies. In order to have a successful program it is necessary to practice good sanitation to eliminate conditions that are favorable breeding places for flies. Keep manure as dry as possible and avoid spilling water and food. Because wasps only parasitize fly pupae, measurements to eliminate adult flies are also recommended.
