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


Natural generation[edit]

Infested stone bricks are occasionally found in strongholds 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[1], with the latter within igloo basements.

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

Mineral veins[edit]

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 which is at least partially occupied by one of these biomes:


Are generated when a silverfish enters the respective normal block form.

In Bedrock Edition, letting a silverfish enter any stone brick variants or cobblestone has a high chance to turn these blocks into infested stone instead of the corresponding infested block. Because of this, infested stone can also be found outside mountain biomes in this edition.



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

Block Infested Block
Hardness 0.75
Breaking time[note 1]
Hand 3.75
Wooden 1.9
Stone 0.95
Iron 0.2
Diamond 0.15
Golden 0.35
  1. Times are for unenchanted tools in seconds. For more information, see Haste § Instant mining.


When mined, infested blocks will spawn a silverfish which will instantly attack 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 will break, spawning other aggressive silverfish. If the silverfish is killed in one hit then nearby infested blocks will not break, and no silverfish will spawn from them.


Note blocks placed on infested blocks will produce piano sounds, while those placed on non-infested stone, cobblestone, or stone bricks will produce bass drum sounds.

In Bedrock Edition, infested block take longer to break when using pickaxe than the stones they appear as, but without pickaxe, they break faster, which can be used to tell them apart.

Mining an infested block with Silk Touch drops its non-infested counterpart, and does not spawn the silverfish.

A silverfish will 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.

When an infested block is destroyed by a player in Creative mode, a silverfish is not spawned.
