However, this last Halloween I went batty (pun intended) and cut creepy-crawlies-and-flyies from scrap cardstock and hung them around the room with thread and tape. (My favourite trick is to tape them on the inside of a lampshade so they surprise you when you turn on the light. GAH! SPIDER. Oh right, I did that.)
Oh course, the cats removed them, one-by-one, so all I had to do after Halloween was pick them off the floor and put them in the trash.
