Possibly a baby spider

6183 From Toronto: Found a huge black spider in the bathroom, could fit over a toonie, not hairy legs but thought it could be a black widow, sorry no pix, freaked out and just killed it. also next to it a speck of dust that moved, so a baby.. ID?

Number 6183 – I believe that it is extremely unlikely that your spider would
have been a black widow; it also is extremely unlikely that the moving
‘speck of dust’ would have been any baby spider.
