|Deer Fly biology, identification, image, control tips and
products for eliminating deer flies.
Deer flies are usually pests of domestic and
wild animals, but will annoy and bite humans as well. The Deer Fly feeds by sucking blood
from its host and
causes a painful bite. These pests are closely related to horse flies
and are often confused with Horse flies; Deer flies are a little smaller in
size than the horse fly.
The wings of deer fly have dark markings and their body is tan or dark in color.
The female Deer Fly feeds on animal
blood; male Deer Flies collect pollen. Deer flies deposit their eggs in
damp areas around bays, lakes, ponds or swamps. The larvae of this fly feeds on
insects and can be found developing in wet areas.
Since the best fly extermination program (for most fly species) involves ridding
the area of the fly's breeding and feeding source, biting flies are most
difficult to exterminate.
- The nature of this fly makes it impossible to eliminate
through spraying programs. If Deer
Flies are found inside a structure, make sure that all possible entry points have been
eliminated. If necessary, a pyrethrin
aerosol can be used in these rare instances.
- Horses, cattle and dogs can be sprayed
or washed with an approved Permethrin solution. Use only Permethrin
products that are labeled for animals.
- For extra protection from biting flies
(as well as chiggers, punkies, no-see-ums, etc.) there are products made for applying to
your skin and others for applying to your clothing. DEET is used extensively for
repelling or killing various insects on people but is not always as effective on biting
flies as it is on mosquitoes, ticks and a few flies. The best biting fly repellent
(for human use) is Sawyer's Broad Spectrum
Composite Spray. Broad Spectrum contains the perfect combination of DEET and
R-326 which is effective against biting flies.
