You aren't alone there mothra.
Way I see it ? It is a challenge .. overcome your fear.
A fear which is really quite irrational, 'cos they don't really know you exist, and YOU are much more powerful than they. Put a duster to them and they try to escape. Wipe 'm up and put'm outside.!
I don't kill critters normally. They have their place. Outside.
Mind you I have a few Daddy-Long Legs in residence. They are excellent bug catchers.
I live in a very dynamic and living environment. A Land For WildLife property, and the diversity of all manner of critters is astonishing. The fecundity of nature is astounding.
If you are seriously arachnophobic, make sure your windows and doors are screened, and effectively, in place. Don't leave unscreened doors or windows open.
They can't really hurt you. Only your fear does that.
