Pest Control


The pest control achievement is obtained by closing 25 maws or culverts with plugs. Completing this achievement takes you 25% of the way towards the master version.

Master Pest Control Achievement

Plug 100 maws or culverts.


Plugged maws and culverts cannot be unplugged.

Even though plugging culverts in an unpurified deep biome results in the plug exploding and the culvert unplugging itself, it still counts towards this achievement.
