The Flies Are Coming!!
Fly Parasites for Livestock

The Best Fly is a Dead Fly.  Even Better is No Fly!

Goat Program

Every livestock farm, zoo or dog kennel knows flies come each year from natural sources such as manure, compost, wet feed areas, etc. Fly parasites will provide the best fly prevention because they will canvass your facility and reach areas where fly development is happening. These tiny pin head size insects nocturnally canvass an area and burrow down stinging fly pupa which kills it and stops fly emergence thus far fewer flies hatch to bother you or your animals.

Silent, unseen and deadly, they prevent fly emergence and are harmless to animals and the environment. A safe method without bringing chemical sprays and poisons to your facility.

Useful Farm Products has been supplying fly parasites to nationwide customers for 35 years. Unlike insecticides, poison chemicals or sprays fly parasites come with no warning labels because they are totally environmentally safe and effective. If you haven’t used them now is a good time to start a program. We have offices located in Florida, Michigan and Arizona to provide service and product.
