Infestation of flies. Anyone help.

[notacooldad]

Yesterday I came home to find my living room window full of flies. The living room door and window was shut.
I got rid of them. An hour later they were back, all over interior the shuuer blinds.
This morning there was bnome there but by 11.00 oclock the window us covered again.

Theres none else where in the house Theres no food in the living room. The house is clean and tidy. Theres no chimney access. What the hell us going in and how can I get rid of them.
Has anyone got any ideas please?

Have you checked the whole room, under all furniture, in cupboards, behind radiators, gaps in skirting etc? . It doesn’t have to be coming from somewhere in or near the bay, it could be anywhere in the room, the flies will fly towards the window.

Maybe if you sit in there and watch long enough 🤢 you can see where they are coming from.
