Minecraft wiki entry for Combat, associated text: One silverfish only deals very little damage 1, or 0 with better quality armor on. However, when the player attacks a silverfish, it can summon other silverfish hiding in other nearby infested blocks. This problem can be solved by killing a silverfish in one hit. In Java Edition, the player can do this with any type of axe except a wooden or golden axe. In Bedrock Edition, the weapon of choice should be enchanted with Bane of Arthropods or be used only with critical hits instead.. With the sharpness enchantment, the player can also do this with a stone axe, iron axe, or diamond axe or diamond sword. If the player is going to the End and the silverfish spawner in the end portal room is bugging the player, they can go ahead and destroy the spawner. Silverfish don't drop anything upon death, so it won't be useful to make a silverfish farm unless the player wants an XP only farm.
