Make 1 foundation and put 8 walls on it making a 2 high box without a lid, drop the spider into this funnel like trap, when you see it's legs show through the trap from the outside look at them directly and you can feed it, you do not need bug repellent for this
If you tame this creature outside a cave(especially revival tame etc.)Creatures on every cave will still argo you, if you want to be ignored and be vulnerable(unless u don't attack any of them) against cave creatures/caves, tame a araneo/arthroupleura inside a cave, once you've tamed it, no cave creatures will attack you(unless you won't attack them). idk if this work on pc, but works on mobile for me.:v
To tame these you will need bug repellent, as they aggro on you otherwise. Then, approach them carefully, making sure that you don’t get too close, or the will attack you. Feed spoiled meat for maximum taming speed. It is best if you find one that is alone. Thanks for reading
Cheesy tip: mount a scorpion or Arthepluora or even another Araneo, walk up to the one u wanna tame while sitting on your tamed insect and feed it. For some reason none of the Dino in game agro on insect type dinos what so ever ;)
So, biggest thing no one tells you on here. If you only have repellant and no ghille, put it on and go at them from the SIDE!! Not head on, not directly behind. The side. Never aggros on you that way. From the back and front even with repellant it aggroed 3x each before i tried it this way.
