We have 3-10 large black flies daily that only appear in one room that has 5 drains connected to a septic system. No other rooms in the house have this problem. Are there more than one type of drain fly? Most of the articles I've read reference small flies and these are large house flies.
We really would like to know what type of flies you are dealing with and more information. Please call us at 866-581-7378 so that we can better assist you in treating this matter. We look forward to speakoing with you soon!
