About Dairy Fly Control & Parasites

Dairy Fly Parasites is a website exclusively devoted to providing Fly Parasite control to dairies large or small - anywhere in the USA. Our company Useful Farm Products has been supplying fly parasites to dairies and other livestock farms for over 35 years. Our parasite mixture is especially designed for dairy use.

Dairy Fly Parasites are incredibly effective - easy-to-use and shut down the flies breeding cycle without any damaging effects to your livestock, environment or you. If you have used Fly Predators, Fly Eliminators or Fly Parasites before, you know how effective these methods can be.

Don’t wait to Stop Flies: If your animals and family are already bothered by flies act quickly. Each adult female fly can to lay up to 500-1000 fly eggs. It won’t get any better until you start taking action and stop the fly cycle. Fewer flies mean higher milk production.

Our fly parasites are shipped in units. Each unit has approximately 10,000 parasites. We recommend weekly shipments for best protection against fly development or fly outbreaks. We can customize plans specifically for your dairy. Call us at 888-771-3276.

Our experts are available for any questions and guidance as you implement your fly control plan.

Fly parasite plans shown here for dairies can also be used for stockyards and hog farms. If you desire fly parasites for horses, deer, or other livestock please go to flyparasitesforlivestock.com.

The best fly is a dead fly. Even better is no fly!
