Moth flies, scientifically known as Psychoda spp., are small, dark-winged insects resembling tiny moths. They thrive in damp, organic-rich environments—perfect for bathrooms with poor ventilation, leaking pipes, or standing water. Their rapid life cycle allows populations to explode quickly, making early detection essential.

Signs of Moth Fly Activity in Bathrooms

Visible moth flies are often the first clue; however, their larvae leave telltale signs—tiny black specks in shower corners, grout lines, or around sink drains. These larvae feed on mold and decaying matter, indicating hidden moisture issues that must be addressed to prevent recurring infestations.
