Anti Silverfish
I don't know my version or loader
AntiSilverFish
Do you hate silverfish?
Well, I do, but this plugin wasn’t born from pure hatred. Minecraft 1.21 added the Infestation potion, where players, with just one well-aimed splash or arrow, can turn a base into swiss cheese if nobody’s watching.
This is a very straightforward plugin that stops silverfish from spawning inside infested blocks,
from re-entering blocks, and optionally disables the Infestation potion effect entirely.
So, This plugin gives server owners three simple toggles to keep that chaos in check:
- Block Silverfish that try to spawn from Infested Blocks.
- Stop Silverfish from re-entering into Blocks.
- Disable the Infestation effect itself (potions, lingering potions and arrows)
Requirements
- Java 21 or newer
- Any Bukkit-based server
- A permissions plugin (only needed if you want to give non-ops access to
