I think also while they’re in there you can’t sample(feed your OT) anything after midnight, to avoid early mutation… 
(@PeteRabb , Don’t tell anyone I’m being serious, but I think you just need to open up you OT and carefully take the spiders out anyway you can. I think I would use some sort of anti-static cloth and maybe a q-tip, but I wouldn’t go as far as alcohol, and compressed air can sometimes leave a residue. Don’t use a vaccum because it creates a lot of static. I’d be super careful about all of this, and only do it when you are ready and feel comfortable in your decision, in other words, don’t blame me if you break it! 
If it were me I’d also make sure to safely relocate them…
