Deer Fly Management for Homeowners
A bite from a deer fly (Family Tabanidae) is a truly unpleasant experience. It is not only painful but many people have an allergic reaction that results in a swollen itchy welt at the sight of the bite. Although there are not many management techniques, homeowners can make a trap to help limit some activity in the backyard.

Remember never to use motor oils or other unlabeled products in managing these insects that could have harmful consequences to other animals or our environment.
