Hi Lille

Swot them with an old tea towel like I do

We get lots of them - I think they're attracted to the compost caddy we keep in the kitchen

I've got a couple of the fly killers in the shape of sunflower that you stick on glass. They definitely work because the window sill resembles a grave yard - not very pleasant to look at but it's better than having them all flying around and there's no smell like there is with fly spray.
