Est. 2026

Ant colonies grow fast—and most habitats don't. After years of stressful and escape-prone expansions, we decided to make our own formicaria.

Modular FlexGrid ant formicarium: a black outworld with clear lid beside a black ant nest with dusty red gypsum.

The Nest

A Home That Grows With Them

The driving principles of Crawlspace Habitats formicaria are modularity and ease of use. We build habitats that anticipate the successful growth of your colony by being seamlessly expandable. No tubes, no screws, no escapees. Just snap on another module.

The Process

A Precise Endeavor

Our FlexGrid ecosystem has been through extensive research and development, adapting to sustain and contain even the smallest ant species and pushing our manufacturing capabilities to their limits. Every product is meticulously engineered.

The Factory

An In-House Company

We're a small business of three guys trying to make your ant-keeping experience better, and we design and manufacture everything in our Philadelphia apartment. Because we make it all in-house, we can iterate fast and build custom formicaria on request.
