Horse and deer flies, although sometimes used interchangeably, are actually different species. They are both large, blood-sucking flies that can make spending time outdoors miserable. Here's a closer look at these summertime pests:
Appearance: Both horse flies and deer flies are large, robust flies with broad heads. Horse flies can grow up to an inch long, while deer flies are slightly smaller. Deer flies are typically brown or gray, while horse flies can be black, brown, or gray with spotted abdomens.
Behavior: These flies are strong fliers and can be quite aggressive, especially females who need blood to develop their eggs. They are attracted to dark colors and movement, and they will bite exposed skin on people and animals. Their bites are painful and can leave itchy welts.
Lifecycle: Both horse flies and deer flies lay their eggs in moist areas, such as near ponds, marshes, or wet woodlands. The eggs hatch into larvae that live in the mud or soil for several months before emerging as adults.
Habitat: Horse flies and deer flies are found throughout North America. They are most active during the day, especially on hot, humid days.
Control: There are a number of things you can do to reduce the number of horse flies and deer flies around your home:
Eliminate breeding sites: Get rid of any standing water around your property, such as in clogged gutters or birdbaths.
