Someone told me to put conkers in the corners of the room and this scares spiders off as they mistake them as big spiders. Now I HATE spiders so thought I would give it a try a few years back and you know what, I have not seen a spider in my lounge since! I had loads, live in the countryside with an open fireplace so they used to come in often but seems the 3 conks are doing their job.....or am I being a ****?
Worked for me, too.
