Door Open - Flies In

We had thought that the season of flies was no and truly over as we relaxed out defences with them. But today they pounced back. As the warm weather had returned over the last week the flies must have been breeding as this evening we had a house full of flies. Our normal shut the door after you routine had diminished and we paid the price as we spent most of the evening being bombarded with dozy flies that had followed the light into the house with the from door wide open.
