Living on a cattle and arable farm we are always fighting the flies away, last year at Burghley I bought the smaller 100ml Simply Green Bugs Away diffuser and at the start of lockdown the flies began making their way from the fields through the door chains and into the farmhouse kitchen – fly swats in hand I searched out the bottle . The bottle has now been in place for 2 1/2 months and I can count on one hand the number of flies which have navigated their way into the kitchen, to say I’m amazed is an understatement. Over the past 28 years living in this farmhouse I’ve tried everything, UV zappers, smelly outdoor traps, window stickers and NOTHING has ever coped with them before . I can’t believe how effective the Simply Green diffuser has been. I’ve just had delivered two of the larger 400ml bottles as well as a candle to use for the BBQ.
