Surviva, IDK if you are still having issues with spiders but the way to beat them is to stack traps and lure them into the traps. Three or four at a time and it should take less than a minute or two to kill a level 3 nest. The spider eggs can be planted near your camp to make a new level 1 nest. Just don't let the nests get past level 3 or they will turn in to spider queen bosses and fuck your shit up. I think 2 or 3 spider nests planted a couple of screens away from your camp should provide you with all the glands and silk you'll ever need. I read somewhere that you can put pig houses next to the nests and they will auto farm but I haven't tried this yet.
