black flies

[neil]

Damn - ever tried killing those little black flies that flutter onto your screen?

Some of them move really fast. Takes a few pokes of the finger to nail 'em.

you could try spraying the window frame with fly killer.
they can smell it on the way in and will then go and annoy your
neighbour instead.

Spray them with starch.
