For some reason bees keep coming in my room - like 3 a night if I have the window open, if I don't then it's fine. We've tried everything and keeping the window shut is the only solution, unfortunately it's getting a bit warm to do this now... so... I thought some kind of piece of net curtain covering just the open part of the window and velcro'ed on or something...
Closest after market product I can find is this:http://www.amazon.co.uk/Window-Filta/dp/B0028SF09I/ref=sr_1_23?ie=UTF8&s=kitchen&qid=1245090933&sr=8-23
Which as a hayfever suffer is probably a double benefit, however, 25 quid seems a bit steep for something I'm gonna stick across a 4-5 foot fanlight window!
Any ideas, or cheaper solutions?!
