Not sure if I should be more concerned that I have snakes around, or more concerned that I have spiders who are capable of hunting them and dragging them up into my garage roller doors. I have also found a scorpions almost a meter up from the ground in their webbing
I think spiders are pretty good engineers with their webs and have ways of using their webs to lift things that would surprise you.
Like attach some webs to the thing you want to lift and anchor them to several places that are close, then wrap another web around those webs and pull that wrap tight and you reduce the length of the webs holding the thing, so it lifts up. Then attach new webs to your main web at several places and wind another web around those ones to pinch them together. Repeat until the thing is as high as you want to get it.
And that’s assuming they don’t set up multiple pulley-like systems to lift heavy things like we do.
Apparently they do though: https://www.livescience.com/spiders-hoist-prey-with-pulleys.html
