Enclosures built to
live together
The world’s first modular hexagonal enclosure system for jumping spiders. Precision brackets hold each cell in a perfect honeycomb — with 1–1.5″ ventilation gaps between every unit.
A new geometry
for spider keeping
Every keeper with more than one spider knows the problem: enclosures stacked on shelves with no coherent way to display a collection beautifully. HexNest changes that entirely — a modular system where each new spider becomes a new cell in a growing honeycomb.
-
Honeycomb bracket system — precision brackets lock each hexagonal unit to its neighbours, creating a rigid, stable grid at any size
-
Forced ventilation gaps — 1–1.5″ spacing means each enclosure sits in its own microclimate with no shared air between cells
-
Arboreal-first interior — tall hexagonal profile gives your spider the vertical space they naturally prefer
-
Front-opening magnetic doors — flush when closed, smooth single-hand operation, dual mesh ventilation panels
Living Lattice: HexNest is launching soon
We’re in the final stages of production. Join the waitlist for early access, launch pricing, and first look at the full HexNest range before anyone else.
Everything you need
to care for your spider
Built by keepers,
for keepers
Fern & Fang Co. started with one question: why are there no enclosures that respect how jumping spiders actually live and how collectors actually keep them?
HexNest is the answer — a system designed from the spider’s perspective first, and the collector’s display second. The knowledgebase exists for the same reason: genuinely good information, freely available, for every keeper at every level.
Every dimension and ventilation choice tested against real spider behaviour and keeper experience.
30 care articles reflecting the same values as our enclosures: the animal’s natural needs come first.
The honeycomb geometry works at 1 cell and at 19. The only limit is wall space.
We’re hobbyists who make products. Every keeper question and idea shapes what we build next.
