DONT put them in a trap, once they agro on a foundation they won’t de-agro.
Use fence foundations to make a trap if you have too.
If your able the best way is to use a Karkino to pick your desired spider up. Then put on your best gillie suit spray some bug spray and sit there feeding it
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
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.
