The moth fly can be found around which area?

• A. Windows
• B. Ponds
• C. Rooftops
• D. Drains

Answer: (D)

Moth flies are drawn to damp, organic material found in plumbing, especially the slime and biofilm that build up inside drains and sewer lines. They lay eggs in this residue, and the larvae feed on it, so the places with standing moisture and messy drains become their ideal breeding and resting sites. That’s why you’ll often see them fluttering around drains, sinks, and other plumbing fixtures. Windows, ponds, and rooftops don’t provide the same breeding environment, so they’re not where these flies are typically found. To reduce them, focus on cleaning drains and removing organic buildup, then keep drains dry and well-sealed.
