Moth flies are commonly found around which area?

• A. Bathrooms
• B. Drains
• C. Kitchens
• D. Living rooms

Answer: (B)

Drain flies breed in the slimy, organic film that can build up inside drains and sewer lines. They lay eggs in that film and the larvae feed on it, so adults emerge right around the drain outlets. That’s why you’ll usually find them near plumbing fixtures like sinks, showers, and toilets. Bathrooms tend to be a common spot because of the persistent moisture and readily accessible drains, but the key factor is the drain itself as the breeding site. Keeping drains clean and free of buildup, using enzyme cleaners to break down the film, and eliminating excess moisture helps prevent their numbers from growing.
