A candle fly, also known as moth fly or drain fly, is a small, winged insect belonging to the family Psychodidae. It is characterized by its slender body and long, hair-like antennae, similar to a moth. Candle flies are usually brown or gray in color and measure about 1 to 5 millimeters in length.
These flies are commonly found near moist and decaying organic matter, such as in drains, sewage systems, and compost heaps. They are attracted to the organic material, particularly if it is moist and fermenting, as it provides them with a suitable environment for breeding and feeding. The name "candle fly" originates from their behavior of flying around light sources, such as candles or lamps, at night.
Candle flies undergo a complete metamorphosis, starting as eggs that are laid in organic matter. The larvae, also known as drain worms, hatch from the eggs and feed on the decaying matter. They thrive in areas with high humidity and are often found in large numbers in infested drains or sewage systems.
While candle flies are considered a nuisance due to their presence in homes and ability to contaminate food, they do not pose a direct health risk to humans. However, their presence may indicate unsanitary conditions or plumbing issues that require attention. Effective control measures for candle flies include eliminating breeding sources, improving sanitation practices, and using insecticides if necessary.
