This guide will let you know what Bane of Arthropods does in Minecraft.
You can apply the Bane of Arthropods onto swords and axes.
It will increase damage against spiders, bees, silverfish and endermites. It is considered one of the least useful enchantments in the game, although it is great for farming spider spawners.
You cannot combine it with smite or sharpness. Ultimately it is not worth using since the mobs, you can use it to kill like bees.
