Infested blocks are blocks disguised as stone, cobblestone, or any stone bricks variants, but spawn silverfish when broken in Survival or Adventure mode.

Obtaining

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.

Breaking

When the block is broken, whether by a player or by an explosion, a silverfish spawns where it was broken. In Java Edition, infested blocks break instantly. In Bedrock Edition, infested blocks take longer to break than their normal counterparts, and take the same time regardless of the tool:

Block	Infested Block[BE only]
Hardness	0.75
Breaking time
Default	1.15

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.

Natural generation

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 cobblestone is found in the rarely generated "fake end portal" room in woodland mansions.

Mineral veins

Infested stone can generate in the Overworld in the form of mineral veins. Infested stone attempts to generate 7 times per chunk in veins of size 9, from altitudes 0 to 64, within one of the following biomes, or within a chunk that is at least partially occupied by one of these biomes:

• Gravelly Mountains
• Gravelly Mountains+
• Mountains
• Mountain Edge
• Wooded Mountains

Post-generation

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.

Usage

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.

Identifying

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.

In Java Edition, using the debug screen, a player can identify whether or not a block is infested.
