Let us help you to achieve the YODER EFFECT

Achieve the "YODER EFFECT"™ for your Poultry Farm

If manure is allowed to accumulate in a facility the flies will come and come fast and be very abundant. You can achieve the "YODER EFFECT"™ for your facility by using fly parasites. This is when the fly parasites take control and the flies are no longer a nuisance.

Let us help you achieve the "YODER EFFECT"™

What is the "YODER EFFECT"™

The following is a conversation I had with one of our Midwestern dairy customers who has a medium size dairy. Mr. Yoder said "I want to tell you a story that happened at my farm. We are Amish and on Sunday in July the congregation came to my farm after church for food and conversation. I was sitting in a chair when a retired dairy farmer approached me and said, "Yoder, there is something strange going on here, very different." Mr. Yoder said, "What do you mean?" The retired dairy farmer said, "Well there are no flies around, no flies by the food and I was down by the sows and there are very few flies down there. What's going on?" Mr. Yoder replied, "Well that's because I use fly parasites and I have for several years and they prevent flies from hatching." The retired dairy farmer replied, "Well they sure are working" and left.

So we call it the "YODER EFFECT"™ when fly parasites have taken control of the farm and destroy most of the flay larva before they can develop into flies. Flies then are no longer a bothersome nuisance on the premises. The "YODER EFFECT"™ works even better in poultry than in open dairies.

Why it happens:

The reason this happens is that when the female fly parasite hatches, she must feed and produce. To do that she seeks out fly pupa (fly eggs) and stings them then she lays her eggs inside the pupa shell. This process kills the developing fly. She will sting several pupa. The eggs she has laid in the pupa will hatch and the new female fly parasite will begin the process over again thus enhancing the process of continuing fly control. The "YODER EFFECT"™ can be achieved and maintained by adding new fly parasites throughout the summer and having the fly parasites reproduce. The fly parasites will colonize and take control.

If you have never used fly parasites, they are nature's way of controlling flies. First discovered in poultry houses over 40 years ago, these beneficial insects only source of food and reproduction is fly pupa (fly eggs). They are tiny pinhead sized insects. The female fly parasite will sting fly pupa and also lay their eggs in pupa. This process destroys the fly so it never emerges. Adding fly parasite periodically along with their ability to reproduce provides the control you need. The fly parasites will colonize and take control.
