Helping the environment is important to everyone, including those who care for horses. There are beneficial biological control methods to control flies and mosquitoes around your stable that will help not only to protect your horses from these annoying pests, but also protect them from the deadly diseases carried by these insects.
Parasitic wasps can be purchased through mail order and are easy to use, safe and relatively inexpensive. When using this method of insect control, there is no need for overhead sprays and direct sprays to the manure pile.
The little fly predators disrupt the life cycle of the insects by seeking and destroying the pupal flies before they ever reach adult stage.
You can find out more information about these beneficial fly eliminators and other beneficial insects at Arbico's website and even watch a video about how the fly eliminators work.
