yes it will... i just sprayed a huge spider with Clorox spray and it died instantly... all its legs curl up and it drops. Eventually it might... maybe it depends on the spider. I sprayed a average sized spider and stood horrified as it twitched for a good 20 minutes. The bleach did at least immobilize it. Yes it does but it's not as effective as spider spray I guess. I sprayed a middle sized spider almost 10 times with Clorox before it stopped moving.
Definitely a writing spider they are peaceful and i think they are beautiful!
