If you’re seeing small flies near the drains then chances are it’s a drain fly. Many people often mistook drain flies and fruit flies due to their similar size. Also, these two fly species hang out on walls and in groups. You can differentiate the two by their appearance on closer inspection. Drain flies are actually fuzzier and resemble moths than flies. Fruit flies on the other hand aren’t fuzzy and look more like miniature houseflies. Anyway, we’re going to take a deeper look on how you can stop a drain fly infestation from becoming worse. There will be also tips on how to prevent from happening again.

How to find the exact location of their breeding ground

It’s really easy to spot the location of the drain flies’ breeding ground. If you see the adult flies flying around on a certain then the breeding grounds are near. Another clear indicator that the drains are the source of the drain fly infestation is larvae. It’s obvious that a larva coming out of the drains means that particular drain is where the flies inhabit. You may have to do further investigation if the drain flies are on an area that has multiple drains. First of all, you need to have a transparent tape. Stick the tape on the drain but don’t fully cover the drain. If you cover the drains then the flies will find another area to get out. This will leave you with no evidence of the flies presence on the drain. After you have placed the tape; you just have to leave it for a few days. Leaving the tape overnight may not supply you with concrete evidence since the breeding cycle of the flies will differ.

Taking out the flies

If you have already found where the drain flies are coming from then it’s time to do a lot of work. The reason why these flies turn your drains into a breeding ground is because of organic matter stuck in the drain lining. Basically, clogged residue and debris are causing the drain fly infestation. You need to remove the clog with all the drain-clearing tools and supplies in your arsenal. Below are the steps and the equipment you need to clear the drains.

  1. First of all, pour hot water into the drain. Ideally, you can pour 2-4 litres of boiling water into the drain. This process will help dislodge sticky residue. It’s important to take note that you shouldn’t use this method if ever you’re clearing a drain that has a garbage disposal.  
  2. You can use a drain stick or metal pipe brush to clear off the clogs. You can also a drain snake for better clearing.
  3. After you have cleared off the drain pipes. You should pour a solution that will help remove remaining debris and kill off bacteria. There are many options for your drain-cleaning solution. Enzyme drain cleaners are great alternatives to chemical-based products. Bleach is also recommended. If you want something less corrosive; then baking soda and vinegar mixture is what you need.
