I also loathe spiders, but I accept that they do a good job in keeping down insects in the house which would otherwise spread disease.
I always ignore spiders when I see them, I shudder, but i ignore them, because I know that within a day they will be gone, out of sight, and if i can;t see them, I don;t worry about them.
It is probably impossible to eradicte all spiders from a house - even if youo get rid of the current incumbents, there will be eggs to hatch, and new ones will come in.
Best just learn to at least tolerate them if you posibly can.
