Spider Control.......sounds like a load of old conkers to me!!
No seriously, for a natural enviromental friendly method, place two conkers on the window sills and the spiders will stay away.
A customer told me he heard it on Radio Two, tried it and when I cleaned his windows ..my god there were no spiders. Tried it at home all around my conservatory and it works !!
Apparently, the conkers contain some sort of natural oil which keeps the spiders away.
Now how much is a fair price for conkers, £1 each ??
