Sioux Center, Iowa | Wondering if anyone has had good luck with the fly predator programs, where they send out fly predator larvae to be released on your farm every couple weeks? |

Michigan | Wife used them for her horses, 5-10 horses at any give time, in 2005 and 2006. Last year 2007, she skipped the program. Very few flies in the years she used it - last year flies were all over. It may have been just a bad year for flies or the predators are effective. They do not bite and you really never notice them. I think she ordered them for this year.
I don't know how they would work on a large operation or if it would be cost effective.
Just a note - if you use them, they come in a box in a larvae state. You are supposed to watch them and when they start hatching then you release them. Well she let them hatch in the entryway to the house (it had been below freezing and she brought the box in from the barn - forgot she put them there) - Anyway you are actually buying some type of insect as we found out (it seemed like there were millions of them). |

| I used them last will and will use them again this year. We only have 6 cows, 5 horses, 50 chickens, 3 dogs and numerous cats. Last year was a huge improvement over the previous year. We really didn't notice the flies at all. |

Chilliwack BC | We have used them for about 4 years and will continue to do so. As others have said, you can't really tell that they are working other than you physically notice there are less flies. It can be sort of pricey but sprays and sticky tapes are too and are more difficult to deal with. |

Van Meter IA | Suppose that it would keep the flies down in a 2600 head confinement building. Be really nice if it would. |

Chilliwack BC | I have no hog background so cant really say. We are dairy though and got the idea from our neighbor who has poultry, so the parasites do work in a confinement barn. |

| What are some of the names of companies selling a fly predator product? |

SW MN and Gold Canyon AZ | Chip , a I use a residual fly spray called Tempo. We spray it on everything after cleaning out the barn, and then respray about 1 1/2 months later. Also use a pit additive to keep the pit from crusting. We also spread some fly bait around the barn occasionally. Hardly any flies. |

Chilliwack BC | We order it through a horticulture fertilizer dealer. Offhand I dont even know the name of the company that supplies the wasps. I do think it comes from the States though. I googled "fly wasp parasite" and came up with this link.
