Infested blocks are not obtainable by Silk Touch, and are only available 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. Infested blocks take less time to break than their normal counterparts would with a fist, and take the same time regardless of the tool[Bedrock Edition only] or broken instantly[until JE 1.17][upcoming: BE 1.17.0] or half as much time as their normal counterparts[upcoming: JE 1.17][planned for Bedrock Edition 1.17.0] .
When mined with a tool not enchanted with Silk Touch, an infested block drops nothing and spawns a silverfish that immediately attacks the player. If the player attacks a silverfish directly with a sword, bow, or potion of Harming, or when a silverfish takes poison damage, nearby infested blocks break, spawning more aggressive silverfish. If the silverfish is killed in one hit, then nearby infested blocks do not break, and no silverfish spawn from them.
When mined with a tool enchanted with Silk Touch, however, the equivalent non-infested block is dropped without spawning a silverfish on all game difficulties. Any Silk Touch-enchanted tool (including swords) will cause an infested block to drop its non-infested equivalent (that is, a pickaxe is not required). A player wishing to collect stone bricks from a Stronghold safely should use Silk Touch-enchanted pickaxes.
Infested stone bricks are occasionally found in strongholds, mountains and igloo basements in place of normal stone bricks. Infested mossy and chiseled stone bricks also spawn in igloos. Infested mossy and cracked stone bricks do not generate naturally within strongholds, with the latter within igloo basements.
Infested stone can generate in the Overworld in the form of blobs. Infested stone attempts to generate 7 times per chunk in blobs of size 0-13, from altitudes 0 to 63, within one of the following biomes, or within a chunk that is at least partially occupied by one of these biomes:
In Java Edition 1.17 and Bedrock Edition 1.17.0[upcoming], infested stone attempts to generate 14 times per chunk from levels -63 to 63. It can replace stone, granite, diorite, andesite, tuff, and deepslate. If it replaces tuff or deepslate, it will become infested deepslate.
Infested blocks are generated when a silverfish enters the respective normal block form. In Bedrock Edition, letting a silverfish enter regular stone bricks turns them into infested stone instead of the infested stone bricks.
When mined, an infested block spawns a silverfish that immediately attacks the player. If the player attacks a silverfish directly with a sword, bow, or potion of Harming, or when a silverfish takes poison damage, nearby infested blocks break, spawning more aggressive silverfish. If the silverfish is killed in one hit, then nearby infested blocks do not break, and no silverfish spawn from them.
Note blocks placed on infested blocks produce flute sounds[Bedrock Edition only] or harp sounds[Java Edition only], while those placed on the non-infested stone, cobblestone, or stone bricks produce bass drum sounds.
In Bedrock Edition, a player can distinguish infested from normal blocks by observing that an infested block takes longer to break when using a pickaxe than the stone it appears to be, but without a pickaxe, it breaks faster.
A silverfish does not spawn if the block is destroyed by the ender dragon.
