IME acrylic walls are just slippery, and my jumping spiders have all had some issues with getting a good grip at times. It gets worse when they are full (as they weigh more, and have more to hold up) and when they are older and their grip is worn out, but also when they're closer to molt. At this point, I'm personally just not leaving any walls without some assistance on them. Here's some examples (note that I am not endorsing any particular seller of these items, I am just linking to the first good example of these that I found)-This kind of mesh, comes up if you just search "jumping spider mesh"-3D printed climbing walls, there are lots out there you can print yourself if you have access to a printer, too.-Tulle-hot gluing small ledges to the walls so if they slip they don't fall far-just lines of hot glue on the walls-use an xacto blade or a pin or other sharp object to etch small grooves into the acrylic directly:
