Why do I have drain flies?
Drain flies, also known as moth flies, sewage flies, and filter flies, like to lay their eggs in wet organic matter. Organic matter can typically be found in clogged and greasy drain pipes in kitchens and bathrooms, storm drains, moist compost, and septic tanks.
Adult drain flies feed on decomposing organic matter and sewage. Their larvae feed on bacteria, fungi, and other microorganisms that develop in drains, standing water, and even sewage treatment beds. If food runs out, drain fly larvae may eat each other.
How worried should I be about drain flies?
Drain flies are not known to bite or transmit any diseases to humans. However they can trigger bronchial asthma in susceptible individuals and their larvae can cause myiasis, a parasitic infestation in which the larvae grow inside human tissue.
Unfortunately, female drain flies deposit anywhere from 30 to 100 eggs, so an untreated infestation will eventually lead to hundreds of flies in your home or business.
Home remedies, such as pouring boiling hot water or bleach on drain flies, do not solve the problem. Without the removal of clogs and appropriate cleaning of the pipes, adult flies will repopulate in the very same drain.
To effectively eradicate a drain fly infestation for good, you need the help of a professional pest control service, that can ensure all unsanitary conditions and potential breedings and feeding grounds are properly eliminated.
How can I prevent drain flies invading?
Clean toilets, sinks, bathtubs, shower and floor drains, Remove rotting produce immediately, Move dumpsters as far away as possible, Areas must be kept as dry as possible, Repair broken or loose ceramic floor tiles, Install fans at entrance points, Fix leaks and remedy condensation, Eliminate standing water and mold
