Perhaps you might want to start a fly nest (let some fruit rot and you'll have 'em there faster than blinking ), you might be able to lure him back with this prospect of tons of food.
To put him back outside, put a piece of paper on the wall/surface he's crawling on, wait for spider to crawl onto it, clap a jar over spider, put spider-in-jar (paper holding jar's top closed) outside, tip jar on its side or turn right side up, remove paper. job done.
I sat there on the couch, with the sleeping cat, and watched that thing make it's way all the way around the room. I missed almost three episodes of CSI Miami over this. This is when CSI Miami first came on TV, not the 300th repeat they seem to show nowadays!!
It finally got round to where we were sitting, scurried down the wall, and across the floor - that is when Mademoiselle decided to dispose of it.
She quite likes them as crunchy snacks, more often than not in the morning I find the remainders of a half munched octopode on one of her various beds. Since we have her, we rarely have sighted a 'Wolfer' as we call them in Bernese Dialect
Not mine, he would move out rather than deal with a spider. He once had to suck one up in the vacuum cleaner when home alone and left it running all night so that the spider couldn't come back out again.
He's petrified of even the tiniest little spider so I deal with them all here. They don't bother me at all and I just pick them up and throw them out.
The cat is a pretty good spider catcher too but I try to get to them first as I prefer to release them alive outside.
