Minecraft wiki entry for Mining, associated text: The easiest way to transfer silverfish to different places is by leading them through the Nether. The player can do this by putting a nether portal by a silverfish spawner, however they will need a path of blocks they can't enter, and another portal for players, farther away with a different exit. After luring a batch of silverfish through their portal, they go through theirs. The player will have made walls and a trail in advance. The walls and trail contain the silverfish, but lets the player see and follow them without being able to reach them. Two levels with a glass walkway for them above their path can do this, just make sure they can't reach the player's level (and none of the blocks are stone they can enter). Also, they may need to see the player once without glass, so they know where they are. Then lead them to a third portal leading to their mine, and voila, the player have transported them to where they want to mine at.
