big horrible, dirty buzzy things. how can i stop them flying into the house through my open windows? is there some oil or scent that they hate, that i could put on the window sill - i heard that maybe mint or eucalyptus may work? thanks.
We get them coming in through the conservatory at night (along with various other beasties), and find citronella candles work well. You can pick 'em up really cheap at Wilkinsons.
