Put away the sprays and swatters - nature has provided biological control for flies in the form of fly parasites! These tiny USDA-approved beneficial insects seek out fly pupae and lay their eggs inside them as a natural process of their reproductive cycle. The fly parasite larvae then consume the pest fly’s larvae. Fly parasites attack several species of flies commonly associated with animals. These beneficial insects live near manure and waste disposal sites, completely unnoticed by humans or animals. Works on 15-40 cows or horses (approximately 40,000 parasitized fly pupae). The flies are shipped in the stage where they are inside the pest fly’s pupae. Allow extra delivery time.
