How to get rid of cluster flies in loft?

My loft is an annual roost for cluster flies, thousands of them...

I could smoke bomb the whole loft, and/or use a slow release insecticide.

Does anyone know of a "bat friendly" way of getting rid of these flies as the above may be a bit harsh on any potential bats that may be living in my loft..

PS, not sure if this is the right forum so will post in other forums too, moderator please feel free to move the topic....

Would fly paper work? It would trap flies but not bats I would have thought. We use the paper in our kitchen , not pretty I'll admit but clean and effective.

No I don't think fly paper would work, the tpe of flies (cluster flies) don't have the same "flight pattern" as the housefly that will and on certain places if you see what I mean. Cluster flies are real dozy, lazy flyers and randomly bumble about. An insectocuter may work but it is the sheer volume of flies too...

Still I do have some papers and will give it a whirl, nothing ventured and all that...

Was really after a spray or smoke bomb that is bat friendly..

Do you know for sure that you have bats in the loft?

If you have, they should do a reasonable job of eating their way through the pests.

I have found them in there from time to time but not sure if they have taken up permanent residence there. They may be in the soffits or the cavity and stray into the loft now and then.....

Just looking for a "bat friendly" insecticide to fog the whole loft if anyone knows of one??

Ok another try.
As you are worried about the bats and rightly so a "smoke" type of fumigation may not be ideal as is the case with a lot of insectasides.
You could try asking somebody like Rentokil who will probably be able to advise on a specfic product.
In the meantime , and this may sound daft but I've done it and it does work to reduce their numbers , you could try a vacuum. Using a vacuum cleaner such as a Henry type with a long nozzle simply suck the little beasties out of the air. If you only have one light on it will tend to attrach them and that's where they will meet their doom. Granted it will be unlikely to remove them all but what have you to lose?
