Freddie's Family - the never ending story....

Well, I sprayed half a can of Paral on the places where the spiders were. The wind blew it back into my face, and after I had stopped choking thanks to the speedy use of my asthma spray, I looked outside and saw some cheerful spiders jumping up and down and thumbing their noses at me. What a waste of my good fly spray! After watching the merry antics of F's family for another 24 hours, I asked the girls on the scrapbooking forum over at DC if anyone had a hot tip for me. Sue B told me to try hair spray. As most hair sprays really smell awful, I thought that it was worth trying, even if it only stiffened the hairs on their little legs....Decided to do the evil deed this morning before I left for work. So I sneaked onto the balcony, armed with a pump bottle of super-hold hair lacquer from A*** (guaranteed to fix the most extravagant punky hair styles) and sprayed, under the motto, *Let us spray*. Well, it smelled even worse than the fly spray, but as there was no wind, it arrived at its destination in enemy headquarters. Then, cowardly as I am, I left them to their fate and went to work. I got home again at about 7.30 this evening. No spiders. No bungee jumping in front of my window. OMG, what have I done?? I still have a compulsive urge to look out of the window and see if they are there, but it's all quiet outside.
Anyone got a good tip for cleaning super-hold hairspray off the window??
