I’ve been hearing this homepsun tip a lot recently - placing conkers in the corners of rooms keeps spiders away. It’s the time of year in the UK where they seem to be at their most visible. It sounds faintly ridiculous, but a google search turns up assorted hits saying that it does, in fact, work.
Time to get the SD. Past time in fact, given the arachnobeast currently in residence chez Scissors. Does it work, and if so, why does it work?
ETA: In case you’ve not seen a conker, it’s the fruit (?) of the horse chestnut tree. A hard brown nut-like sphere that schoolboys used to collect in days of yore.
