Drain Flies/Moths - Signs of Household Plumbing Leaks
Drain Flies aka Moth Flies
Drain flies or moth flies are small, dark winged gnats. They breed in standing water which makes home drains the perfect breeding grounds for these irritating insects. Most of the time they are noticed after you come back from a vacation or you have been gone away for an extended period of time. This is due to the water just sitting inside of your homes drain traps without any water moving through the pipe system.
If drain flies are noticed don't panic because they will usually disappear once normal household activities resume and the water in the home is once again being used daily. If you have not been away from home and you start to notice these flies you may have a plumbing problem that you are unaware of.
Drain Flies and Breeding
Drain fly larva need moisture to grow. The perfect places inside your home are the sink drains, toilets that are not used often, and anywhere in general that water may accumulate and sit for periods of time. It is a good idea to clean those types of areas consistently to avoid an infestation of these flies. Being that the larvae are so small it is hard to see them and they tend to be overlooked. By the time they are noticed they have already grown to adult flies.
In some instances the breeding area is outside of the home and the adult flies find their way in through windows, doors, etc. This can cause some confusion because you will be finding adult flies inside but you will not be able to locate water that they may be breeding in. So it may be a good idea to look outdoors as well for your source of standing water.
Drain Flies and Your Home
So you noticed drain flies inside of your home, what do you do? Well first you want to flush clean water through your homes drains and pipe system. You can run hot water down drains and flush all toilets. Also clean other areas where water may be laying such as; under the refrigerator, air conditioners, other appliances, and empty all standing water that is found outdoors. If the problems persists you may be facing a bigger issue.
Although drain flies are a nuisance they may also be a hero. I am sure some of you are saying "what, is she out of her mind", right now because you may have experienced these flies in the past. They can be a hero because you may have hidden leaks within the walls of your home or in some other place indoors that you do not check or see often. They will breed in any moist area that they can find. So if you are facing a drain fly infestation that you can not get a handle on you may want to look deeper for the cause of these insects. It could be stemming from a leaking pipe or drain under the sink or even a leaking pipe inside of your walls.
Once you find the cause of the drain flies you will be able to make any needed repairs and then rid yourself of these pests once and for all. But first I would suggest thanking them for saving you money by showing you to the plumbing problem before it was too late. Leaky pipes that are left to leak over periods of time can cause major problems to your home. The worst is causing the woodwork to rot away right in front of your eyes. Also a pipe that is leaking slowly can very quickly turn into a pipe that will flood your belongings and ruin every thing in sight.
Ridding Your Home of Drain Flies
Remember if you notice drain flies in your home you should start by flushing the drains and pipes with hot water. You should flush all toilets especially ones that are not used often. If problem persists for an extended period of time remember to look deeper for the problem. It make be caused by leaking pipes that are not visible. Also do not allow water to stand for periods of time in objects outside of your home because it may become a breeding ground.
Once the moisture problem is taken care of the drain flies should diminish. If the problem does not lessen or diminish you may want to contact your local exterminator for assistance.
