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:

1. Block Silverfish that try to spawn from Infested Blocks.
2. Stop Silverfish from re-entering into Blocks.
3. 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 /antisilverfish reload)

Installation / Usage

1. Drop the jar into the plugins folder and start/restart the server.
2. Edit plugins/AntiSilverFish/config.yml to taste (all options are enabled by default).
3. Run /antisilverfish reload to apply changes without a restart.

Commands

/antisilverfish reload – reloads the configuration.
