Fall Flies in Lebanon, MO: Identification, Prevention & Professional Control

Why flies spike in fall
Shorter days and cooler nights push cluster flies to seek attic and wall voids for overwintering. House flies follow food/garbage and slip in through doors, screens, and utility gaps.

Quick ID Guide

Cluster flies (the attic drifters)

• Larger and more sluggish than house flies

• Often gather on sunny siding and windows

• Emerge from attics on warm winter days

House flies (the kitchen nuisance)

• Fast fliers; tied to trash and food residues

• Breed where organic material accumulates (bins, garages, livestock areas)

Drain flies (if you see tiny moth-like flies)

• Fuzzy wings; hover near sinks/tubs

• Breed in gelled organic slime inside drains         

  Why DIY Often Falls Short

  H3: Surface sprays miss the source
  Aerosols knock down adults but don’t touch larvae in drains, bins, or compost—or cluster flies hiding in voids. Without sanitation and void-targeting, flies rebound.

  Prevention That Works (Lebanon homes)

  Sanitation + exclusion

  • Seal doors/weather-stripping; repair window screens

  • Keep trash bagged and lidded; rinse bins weekly

  • Manage pet waste and fallen fruit; keep compost covered

  • For drains: scrub/flush, then use a bio-enzymatic drain cleaner (not bleach) nightly for 1–2 weeks

  • Outdoor tip: reduce attractants around patios; move bins away from entry doors
