Can the drain flies come in from the Septic Tank?
Unless there is a crack in your drain pipes that lead to your septic tank, the drain flies will not come from that area. Use glue boards over the drains like shown in our drain fly video to make sure they are actually breeding in the drains, not just occasionally going down into them and then coming back out. You will want to treat with a drain gel that will eat away at any build up on the sides of the pipes that the flies can be leaving eggs/larvae behind in. Keep in mind, any area that holds moisture can be used as a breeding ground. Areas like inside toilet tanks, around seals of cauking on sinks and tubs, windows in bathrooms and kitchens, loose tiles that could be holding water underneath, and around kitchen sink hose sprayers, should all be cleaned and checked. You can check out our Drain Fly Kit and article on How To Get Rid Of Drain Flies for the best treatment methods. Feel free to contact us if you have any questions.
