It's the little jumping spiders that I dislike. They seem to face you up with attitude. There are always lots in our garden and in the house. They give a sore bite
I do like the little lizards, unfortunately, so does our local cat who, when we are over leaves us little presents of dead lizards outside the door.
We also had a huge centipede crawling up the settee one night, it was horrible. but we did not kill it, we put it out in the fields. I believe they are quite harmful.
