Flies in Wyoming: what the public record shows
Before you compare quotes, it helps to know which flies actually live in Wyoming, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.
New generations every 10 to 20 days in warm, humid conditions; eggs hatch in 1 to 2 days, larvae 3 to 5 days, pupae 6 to 8 days
Horn fly generation time in Wyoming
Even Wyoming's short high-elevation summer fits several full generations.
University of Wyoming ExtensionEach fly can take 24 to 38 blood meals per day; adults live about 2 to 4 weeks
Horn fly blood consumption
Explains the intensity of biting pressure on animals and people near infested herds.

National horn fly losses
The scale of the problem is why manure management is treated as pest control in ranching country.
University of Wyoming ExtensionFly species recorded in Wyoming
- House fly (Musca domestica) — Non-biting; breeds in manure, garbage, lawn clippings, decaying produce. 45 days at 60°F to 7 days at 95°F. Carries bacteria and viruses causing diarrhea, cholera, food poisonin…
- Stable fly (Stomoxys calcitrans) — Biting fly with bayonet-like proboscis; about 12 days egg to adult; peaks early summer.
When flies are busiest in Wyoming
Short high-elevation warm season with horn fly generations every 10 to 20 days; the final generation overwinters as pupae in manure.
University of Wyoming Extension frames cattle manure management as the crucial control step, since horn flies breed only in fresh dung piles.
