A vivid nest with both humid and dry sections

ANTMART Organic Yellow 220x110, Variant A is a bright ant farm built around a partial-gypsum moisture system. Saturated yellow components give the body a distinctive appearance, while transparent panels keep the nest, workers, and colony development visible. The configuration is intended for ants that need humid chambers for the queen and brood as well as drier rooms for provisions.

Acrylic, PETG, and nylon construction

The body combines 3 mm multilayer acrylic with PETG components. Yellow and transparent parts are assembled with white nylon fasteners. Nylon does not rust when exposed to water or damp gypsum, making it a practical connection material for equipment in which the hydration system is used regularly.

The white hardware complements the yellow, clear, and white color scheme, but its primary functional advantage is the absence of the corrosion associated with metal connections in a humid environment.

G-23 gypsum and a moisture gradient

The nest contains a 6 mm slab of high-strength medical G-23 gypsum. Its porous structure receives water and passes moisture into adjacent chambers. The material’s density reduces its tendency to crumble and makes the surface more resistant to damage by the ants.

Unlike Variant B, the gypsum does not occupy the entire residential floor. This makes it possible to maintain a gradient, with some chambers remaining humid and others staying drier. The colony can place brood closer to the moist area while moving provisions that are sensitive to dampness into dry storage rooms.

Key construction details:

• Organic series;
• saturated Yellow body color;
• nest dimensions of 220x110 mm;
• a 6 mm slab of G-23 gypsum;
• 3 mm acrylic and PETG components;
• white nylon bolts;
• an arena measuring 80 mm in height;
• chamber heights from 15 to 21 mm;
• three residential zones separated by dividers;
• a double acrylic lid secured with mechanical sliding locks.

A rigidly retained arena lid

The 80 mm-high arena provides a separate area for feeding and decoration. Two layers of acrylic form its lid. The double construction increases rigidity and helps limit changes in shape caused by evaporation from the hydration system.

Mechanical locks hold the lid on the body and reduce accidental movement during care or transport. This feature does not replace inspection of the complete farm. Before introducing ants and before every move, check the locks, lid edges, ventilation, fasteners, and connection ports, particularly when keeping small or highly exploratory species.

Three zones for gradual occupation

Removable dividers split the residential section into three autonomous zones. A small family can begin with access to a limited number of chambers. Additional areas can then be opened as the colony grows and fills its current space.

Staged expansion helps the ants organize the available nest and reduces the number of vacant rooms that might be used as waste sites. The next zone should be opened when the current area is occupied and the family genuinely needs more room. There is no need to expose the full nest in advance merely to increase the available floor area.

Species and husbandry applications

The partial-gypsum layout is particularly relevant to Messor. Harvester ants need humid brood chambers as well as dry areas where seeds are less likely to absorb moisture. Chamber heights of 15 to 21 mm also accommodate large workers and queens among compatible species.

Various Camponotus are mentioned in the source as another possible group. Requirements differ between individual species within this genus, so the intended ants’ preferred humidity, ventilation, and chamber dimensions must be checked before introduction.

Variant A may not provide enough background humidity for species that require the entire nest to remain consistently wet. The source places tropical Pachycondyla and Pheidole among the groups that may need the full-gypsum Variant B. That alternative should still be assessed against the biology and dimensions of the exact species rather than selected from the genus name alone.

Frequently asked questions

• Why are white nylon bolts used?

Nylon hardware does not corrode beside water and damp gypsum. It also matches the body’s color scheme while avoiding the rust associated with metal connections in humid equipment. The condition and tightness of all fasteners should still be inspected during routine maintenance.

• What do the double lid and sliding locks provide?

Two acrylic layers increase rigidity, while the mechanical locks keep the upper section in its intended position. This reduces accidental shifting and limits the chance of a gap developing if the material flexes slightly. It does not justify a claim of absolute containment, so the entire assembly must be inspected before transport.

• Can highly moisture-dependent ants live in Variant A?

Variant A creates a combination of humid and dry zones. If the selected species needs constant high humidity throughout the entire residential section, a continuous-gypsum configuration may be more appropriate. Compatibility still depends on the exact ants’ moisture, ventilation, and dimensional requirements.

• When should another zone be opened?

Additional chambers should become available as the family grows and begins to fill the existing area. The correct time is determined by population, behavior, and use of the current rooms rather than by a fixed number of days after introduction.
