Limit a WorldGuard mob-spawn restriction to one region

Applies to: WorldGuard; match the linked maintainer documentation to your installed platform and release.
Documentation checked 9 November 2026.

A spawn restriction can cover an event area without changing survival spawning across the world. Select the intended entity rule and verify the source of the mobs you are investigating.

Follow the procedure

Identify the target region, mob type and spawn source. Natural spawning, spawn eggs, spawners and plugin-created entities may not follow identical event paths.
Read the installed WorldGuard spawning flags and entity-set syntax. Choose a general spawning rule or a specific deny-spawn list according to the actual policy.
Record the current flag and any existing entity list before editing. Preserve intentional entries rather than replacing the list with only the newest reported mob.
Apply the reviewed narrow rule to the named region. Use the documented entity identifier for the installed server version instead of guessing from a display name.
Test the relevant spawn source inside and outside the region using a controlled disposable setup. Existing mobs should be counted separately from new spawn attempts.
Observe normal gameplay for the area and document unsupported plugin-created cases. Keep the outside world’s intended spawning behaviour unchanged.

Check the result

The selected new spawn attempts should follow the intended regional policy, while outside spawning remains unchanged. Existing entities may remain present after a spawn rule changes, so their continued presence alone does not demonstrate failure. Record the exact source and entity tested.

If the result is wrong

If mobs still appear, identify their spawn source and check integration with the responsible plugin. Restore the previous flag list if legitimate entities are blocked unexpectedly. Do not remove every existing entity or disable all world spawning as a diagnostic shortcut.
