Infested Block

An infested block is a stone, stone variant or deepslate block inhabited by a silverfish, which can break out if it is mined or a nearby silverfish is attacked. Infested blocks break more quickly, do not drop as items and can be safely cleaned of infestation using Silk Touch.

Infested blocks are not obtainable by Silk Touch. They are available only through the Creative inventory or commands. However, they can be retained from worlds played in versions where they were legitimately obtainable.

When the block is broken, whether by a player or by an explosion, a silverfish spawns where it was broken unless the difficulty is Peaceful or the game rule doTileDrops is set to false (doMobSpawning is irrelevant).
