House flies
Best fly traps
The best fly trap depends on where the adults are. A ribbon in a barn, porch, or kitchen catches House fly adults while you find the bin, the carcass, or the dirty drain. An outdoor bag baited with a stink lure will pull flies to the door if you hang it on the door. Hang it downwind of the patio, at the distance the product suggests, or you bait the seats.

Which one to buy
Hardware
Sticky fly ribbon
Best indoor trap — Hang ribbons where flies rest, out of head height. They fill up. They do not find the dead mouse in the wall that blow flies are using.
Hardware
Rescue outdoor fly trap bag
Best outdoor bag — Rescue-style disposable bags. Far from doors. Empty or replace them before they rupture. A bag is not a cluster-fly attic treatment. Cluster flies are a wall-void and sealant job in fall.
Hardware
TERRO fruit-fly trap
Wrong trap to avoid — If the insects are tiny and hover over fruit, buy a fruit-fly trap instead. A barn ribbon is the wrong scale.
Traps skim. Breeding sites decide.
House flies breed in decaying organic matter: garbage, manure, a forgotten mop. Blow flies often mean a dead animal. Cluster flies enter in fall to overwinter and do not breed in the trash. Buying one trap for all three wastes the week. Match the fly, then buy the ribbon or the bag, and still remove the source.
Common questions
What is the best indoor fly trap?
A sticky ribbon placed where adults rest, plus a closed trash can. Ultraviolet traps are a commercial option this catalog does not need for a house.
Where should I hang an outdoor fly bag?
Away from the door and the table, so the lure does not invite flies into the seats. Follow the hang distance on the package.
Will a fly trap work for cluster flies?
Poorly. Seal the wall and the attic entry they use in fall. A ribbon catches a few. It does not empty a void.
