If you have a spider in your tub or sink, it usually means they are thirsty. Throw a small drop of water on them they'll love it.

Also be sure to make a little ramp for them to get out if they're stuck. Do not put indoor spiders outdoors. They are adapted to indoors and may not survive outside. If you must relocate them, put them in a corner and they'll find a new spot. Spiders do not want to be near you. They know your pattern.

@creamqueen Won't this drown the spider?

@VirtuousVoyeur no just a little drop
