A few of my customers used a product called 'Cluster Buster' found on Amazon. They all recommended it.

Are they in a loft or a certain space? If so a chemical fogging treatment. If building up in windows then cluster buster traps stuck to the glass. Normally treat em in autumn and spring. 2-3 times will normally break the cycle

Once gone ,use a scent disrupter to break the pheromone trail that lures em back every year. Cheap car air fresheners and  household scent nuetralisers will do.

I don't know about any you could buy without being registered with the pest control suppliers and having ticket for it. 

I would guess emptying a couple of cans of fly spray up there would do it. I bet they have all gone by now anyway as its got warmer?

Exactly what I did. Sprayed the hibernating flies in the  roof space with shop bought fly spray and haven't seen them since.
