Something like this maybe?
I would call the city but the house is abandoned and being remodeled currently. The contractors doing the work are fumigating.
You can buy a bug bomb and super hit the bathroom.
You may have to go away for a weekend or something, we used to use them growing up but never in a bathroom.
Use like 3 of these. My buddy had spiders all over his house, used like 10 of them and now he has no more spiders.
Such an easy fix for this: https://www.amazon.com/dp/B0054NFWH4/ref=asc_df_B0054NFWH45197192
