Plague of flies

[UntamedWisteria]

... here. Think they are cluster flies.

Anyone else got them.

And tips to get rid ...

Yep, they are all congregating in our loft space and window frame seals.
We have just bought some fly bombs from the local farming shop to chuck into the loft and kill the bastards off. No idea what to do about the window ones though as as soon as you open the window to get rid of them, they all fly straight into the house

Not just us then!
