You know they're helpful creatures right?
All they do is kill other annoying insects inside your house. They're basically non-venomous so they pose no threat whatsoever.
You can probably just put them outside or ignore them.
You most definitely cannot ignore them! That's what they want you to think.
They may be 'helpful', but they also are very big and spidery, and have a nasty habit of sitting on walls looking like they are ready to jump on your head at any moment.
I may have told this story on the forums before. Many years ago, I had one living in the air con vent in my bedroom. Every evening I would watch in fear as his legs emerged from the vent and he parked himself on the wall above my door. Bain named him Fred.
One night he held me hostage in my room (it was clear he was waiting for me to try and leave so he could jump on my head). I was banging on the wall hoping to attract the attention of my parents downstairs (usually any such noise was greeted by one of them coming upstairs to put a stop to it). No one came. I was on the phone to Bain, who was trying to give me Fred's life story and telling me he had a family. Finally my dad came up stairs to go to bed, and I got him to come in and introduce Fred to the bottom of a shoe. I was once again free to leave my bedroom.
I will leave Daddy longlegs alone - unless they intrude on my shower. If they stay above the tiles, I will shower in fear while watching the wall. If they come down, they get splashed until they think better of the idea … if they're really dumb they get squashed with the shampoo.
