Can anyone help? We've been plagued with these flies for best part of a year...I'm at my wits end now! They congregate around our main living room window and I can hoover and clean them up to three times a day...but then another 20-30 appear. I keep a very clean house, my fruit is kept in the fridge and I have no house plants. I've tried all the traps for fruit flies thinking they would work to no avail! Also the fly hanging strips do work to an extent but they aren't all attracted to it. Please any advice or help is greatly appreciated!
