Hi Suleyman –

It’s nice to hear from Uzbekistan! Fly Parasites are small beneficial insects that nature has programmed to attack and kill the immature pupal stage of pest flies. For goats, we recommend releasing 250 parasites per animal weekly, every other week, or even monthly. Multiple releases are important because the pest has a much shorter life-cycle than the predator and lays more eggs. Monitor the pest population closely and adjust releases as needed. Keep in mind that fly parasites do NOT attack adult flies so you should employ a combination of measures to achieve the best control. Here’s a few other recommendations.

• Sanitation is the most effective and important step in reducing pest numbers
• Seal garbage cans with tight fitting lids
• Use traps and baits outdoors and in shelters to reduce the number of adult pests during warm weather
• Follow proper manure management practices to reduce populations in animal facilities


Hope this helps!
