Flies in Iowa: what the public record shows

Before you compare quotes, it helps to know which flies actually live in Iowa, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

Three generations each summer; the final generation migrates to buildings during mid to late September

Cluster fly generations and migration date in Iowa

Iowa homeowners have a narrow window to seal the house before the September move indoors.

Houses on exposed hilltops or high ground are most attractive; flies cluster on warm sides of buildings by day and crawl in under eaves, around windows, and through siding gaps at night

Where cluster flies gather in Iowa

The same house gets hit every year, which is why owners assume the flies are breeding inside.

Larvae infest the carcass 5 to 10 days, then wander to pupate; maggots become adults in 5 to 7 days

Blow and flesh fly timing on a carcass

An indoor blow fly wave runs about two weeks from the death of the animal and does not reinfest.

Iowa State Extension: cluster flies hibernate inside walls and under insulation where treatments cannot reach, so seal under eaves and around windows during summer and, if needed, treat the exterior in mid-September.
