Deer Flies | Homemade Traps to Get Rid of Deer Flies

Deer flies are bloodsucking insects; they’re harmful pests to humans and cattle also. They are big flies with enormous brightly colored compound eyes.

They are bigger than the common housefly and tinier than the horse-fly. There are almost 250 species of deer in the genus Chrysops. 

What do Deer Flies eat?

Female deer flies are chronic blood-feeders, but the males do not absorb blood. Instead, they exist by feeding on pollen and nectar from plants. Larvae are aquatic and feed mainly on organic debris. Pupae do not feed.

Deer flies are natural predators comprising frogs and toads,  wasps and hornets, spiders, dragonflies, and some bird species.

Where do Deer Flies live?

Deer flies are abundant in damp, wooded, or marshland environments such as marshes, ponds, and streams.

Reproduction & Life Cycle of Deer Flies

Female flies lay batches of 100 to 800 eggs on vegetation that stands over water or wet areas. Larvae hatch and fall below, where they feed on decaying organic matter or small species in the environment.

Larvae acquire through 6-13 larval stages, the mature larvae crawl to drier regions to pupate, and in duration of a few weeks, emerge as adults. Deer flies normally have a one-year life cycle, but some species may attain 2-3 generations per year.

Female deer flies must eat up a blood meal in order to produce fertile fly eggs.

What attracts deer flies?

Deer flies are mostly found around streams, ponds, damp groves, and marshlands. They are also attracted to farms and other properties that house livestock, horses, and distinct animals.

Both females and males feed on plant pollen and nectar. This implies that plants with an ample amount of flowering vegetation could attract deer flies. Deer flies are barely found living inside homes. 

Deer fly bites

The female deer fly bite comprises two pairs of mouth part “blades” that the fly uses to cut the skin. Once the skin is injured, blood starts to flow and the female then uses other mouth part elements to lap up and consume the exposed blood.

Deer flies will feed on a diversity of mammals that include humans, pets, livestock, and deer etc., The insects usually aim at upper parts of host’s body, such as the head or neck.

Also, deer flies like to attack a moving host.

The common signs and symptoms of deer fly bites:

  • Localized symptoms comprising swelling and an itchy red region around the bite.
  • Constant itching and scratching of bite wounds heading to secondary bacterial infections if the bite is not kept tidy and disinfected.
  • Since deer flies vaccinate anticoagulant-containing saliva during blood feeding, some life-threatening severe reactions may arise in people that are highly allergic to the anticoagulant compounds. Symptoms may comprise a rash on the body, wheezing, swelling around the eyes, swelling of the lips, and dizziness or deficiency.
