Awww I totally understand your concern for spiders. Spiders are my all time worst feared creature!!! I hate them with a passion. Generally the only two spiders we have to worry about in our area (KS/OK) are the brown recluse and the black widow. I think by now if your baby were bitten by one of those you'd definitely see the effects of it in the form of tissue damage, or neurological effects. I am guessing her scratching her bum is from her hair cut or maybe she needs a visit to the vet to check her anal glands. If you are crazy paranoid, you are in good company here.
