If anybody has questions to making a Spider Spawner Trap, I have one that works perfectly fine! Now, there are some videos on youtube that show how to do it, but with cactus, if you don't happen to have cactus in your world, which is rare, and I don't, then I can show you how to make one without it! Just comment if you need help! Oh and be aware that you need slime for sticky pistons! If you don't, then I suggest to make a slime farm, then comment here!
