These flies are hatching somewhere in my kitchen. I don't know where, but this is the 3rd yr in a row they have infested my kitchen. They hatch en masse and I end up with thousands at a time. Could someone let me know what they are?

Sure they are not coming in through sink overflow pipe, hatching in the drain?

These hatch in earthworms.

These hatch in earthworms. They don't live in drains. At this season they are coming inside looking for a place to hibernate.

Cluster flies

If you google Cluster flies, you will find there are masses of sites with advice on how to deal with them, local council sites often. It is a common problem and nothing much to worry about, though a nuisance, undoubtedly.

Cluster flies

Thanks so much for your comments, and thinking about it they could be hibernating in the feather-board cladding on the outside of my barn. It's impossible for me to seal cracks etc, and there is a lot of access for flies.

They are a nuisance, but at least I know what they are now and that they are nothing to worry about. Even though it's horrible it's astounding to see the numbers (it takes a lot of clearing up too!)
