  • When should I buy Fly Parasites?

    Created by Kristy Asao on

    I live in California, the Los Angeles County area. For the fly parasite, what is the best time to release them? Thank you!

    Kristy –

    Fly Parasites should be released whenever pest flies are present at the following rates:

    • large animals (horse, cow, etc.) – 500 parasites per animal
    • medium animals (sheep, goat, etc.) – 250 parasites per animal
    • small animals (birds, rabbits, etc.) – 5 parasites per animal
    • manure/compost piles – 5 parasites per cubic foot

    For best results, start releasing before flies become a problem!
