we had part of our rear garden paved last year, and this year we have an
abundance of small files which fly around the surface of the paving in
large numbers, probably no more than 7mm in length and remind me of pond
skaters, except without the pond. they're not afraid to enter the house
so we're unable to leave any of the back doors open.
the garden is northeast england, east facing and partially shaded by
overhanging trees.
any help in identifying these and convincing them to leave would be much
appreciated.
many thanks
