Cluster flies vs everyday house flies
Cluster flies often overwinter in wall/attic spaces and appear in waves on warm days. House flies usually tie more tightly to garbage and food waste. If you’re unsure, describe what you’re seeing when you call—or start on our general flies page.
How we help
Programs often include attic-focused work and timing around spring/fall pressure. Exclusion tips may help reduce re-entry; see seal-out and exterior treatment.
