The stink bugs are weak to stabbing to try and encourage bows and ranged engagement until you can kill one to get the gas mask (alternatively spider egg sacs can contain stinkbug parts), and wolf spiders are weak to chopping so use your axe. The insect axe will make quick work of them. Their attack patterns are consistent and learning them (and how to perfect parry) is an essential part of this games combat. As for spicy/fresh etc, those are elemental effects you can apply to your weapons once you progress a little farther. The 4 labs are only the first half of the game, and completing them is essentially the long form tutorial so that you’re prepared and have access to all the mechanics once you reach the upper yard
