Formicarium Start

Size a nest so the founding colony fills it and the climate stays even, the corners stay clean, and the colony settles fast. That is the whole logic of the Start. A 9 mm chamber and a 5.5 × 3 × 4 cm arena keep a young colony snug, and the whole nest is cut from clear 3 mm acrylic, so you watch the queen, the brood and every forager without opening anything. It suits the founding stage of almost any colony and houses small species for the long term, around its 200–400 capacity. Popular starters here include Messor structor and Messor hebraeus harvester ants and Camponotus nicobarensis and Camponotus irritans carpenter ants. Small species you can keep for good include Lasius niger, Lasius flavus, Tetramorium caespitum (pavement ant), Pheidole, Myrmica rubra, Crematogaster (acrobat ants) and Temnothorax. Founding queens of larger ants — Messor harvesters and Camponotus such as Camponotus floridanus — start here happily; fast-growing giants like Messor barbarus outgrow a starter nest within a season, which is expected, so connect a larger nest through the ⌀8 mm port when they are ready.

Fill the humidity chamber through the small ⌀3 mm port with a syringe once or twice a week, and the water spreads on its own between the layered sheets by capillary action, damp near the sponge and drier toward the arena, so the colony picks the spot that suits its brood without misting by hand. Top the sponge up before it dries completely and never flood it; a soaked nest is as bad as a dry one. Because it is screwed together, not glued, you can take it fully apart to reset it: move the colony out first, unscrew the layers, rinse in warm water only with no detergents, dry every part, then reassemble. Once the colony fills roughly 70–80% of the nest, or pushes toward the 150-worker mark, connect tubing to the ⌀8 mm port and link a larger arena or modular nest — the ants migrate over on their own.

Your kit arrives flat as about 15 laser-cut acrylic parts, held by stainless screws and nuts with no glue, and goes together in about 10 minutes. One step matters most: peel the protective film off both faces of every part before you build. Leave it on and the nest looks cloudy; take it off and the acrylic is optically clear. The Start holds even small, determined workers with three barriers: an interior slider door, an exterior security door fixed with a nut and screw, and a screw-secured nest lid. Both arena and nest carry laser-cut micro-perforations for passive airflow with no drafts and no fans, your main defence against mold alongside the right-sized chamber.

Soft tweezers move ants, brood and food without crushing anything, and a feeding plate or small dish keeps food off the sand so it does not spoil into the substrate. A syringe makes watering simple. For the arena, start with a thin layer of natural sand or coloured quartz for grip — mind the scale, since the arena is only 5.5 × 3 cm and 4 cm tall, so choose small pieces that clear the 4 cm height. When you scale up, the ⌀8 mm port connects compatible nests and arenas from our formicaria range.

Is it safe for children and classrooms?
Yes — the acrylic is solid and the lid is screw-secured, so with adult setup it suits a child’s first colony or a classroom. Keep the assembly screws and small parts away from very young children during the build.

Do I need to add sand and decorations?
The nest works without them, but a layer of substrate sand and a few small decorations give the colony grip, cover and a more natural foraging space.

What if a part breaks — can I get spares?
Yes. Because the nest is built from individual screwed parts, single pieces can be replaced; contact ANTonTOP with your order and we’ll sort out a spare.

How do I connect it to other nests or arenas?
Use the ⌀8 mm port with a length of tubing to link a larger arena or modular nest. The colony migrates across on its own once it needs the space.
