In reply to lone:
In the UK, mtfu.... would be the insensitive suggestion, and as a non arachnophobic who doesn't get the fear of spiders thing.
In other countries, maybe consider face climbing rather than cracks?
Or, make an eliminate so the spiders work isn't destroyed, but some spiders make new webs daily - so how to tell if its still in use?
The jumpy out of crack things tend to be silverfish. Ladies have a worse time than gents with these little surprises.
