Camponotus vestitus

This Sri Lankan carpenter ant earns its place by being an active, visible species without seasonal fuss: it forages readily in the open after dark and keeps going year-round, so there is no diapause to schedule. Native to the warm lowlands of South Asia, it favours steady heat and a moderate humidity gradient rather than extremes. As majors come through, the colony gains a satisfying caste range to watch. It is a clean, rewarding choice for an intermediate keeper who already handles heating and basic humidity control.

An omnivorous carpenter ant that takes sugars for its working force and insect protein for brood. With no seasonal break it feeds year-round, so keep a sweet source topped up and offer prey on a steady schedule.

Found the colony in a test tube and move it on when the workers blanket the floor of the tube. This tropical carpenter ant wants a moisture-holding nest with a damp core and a drier outer run, so a Ytong or aerated-concrete chamber works, sized up as numbers climb into the thousands. Coat the arena rim with fluon (PTFE), oil, or talc and water, as the workers are nimble climbers. ANTonTOP formicaria and starter kits arrive as one set with the right humid nest, arena, and barrier matched to each stage.

Suited to steady warmth, set the nest at 21-24 °C and let the arena run 18-28 °C, with nest humidity 50-60% and the arena drier at 30-50%. Warm only one side so the ants can settle where it suits them along the gradient. As a tropical species it needs no winter rest and stays active and feeding the whole year.

Things start slowly at founding and quicken as the first workers mature, the colony heading toward several thousand workers. It reaches you as a fertilised queen with workers and brood already underway.

• Camponotus ranks among the most diverse ant genera, with a wealth of carpenter ants across tropical South Asia.
• Carpenter ants tunnel galleries through wood for their nests yet forage outside, so they hollow timber without eating it.
• Many tend honeydew-producing aphids and scale insects, harvesting their sugary droplets like a managed herd.
• They lack a sting and rely on formic acid and a sturdy bite to see off intruders.

Is Camponotus vestitus good for beginners?

It is rated Intermediate, so it suits keepers with some experience of heating and humidity rather than a first colony.

Does the Sri Lankan carpenter ant need a winter rest?

No. It is tropical and stays active year-round.

Does it sting or bite?

No sting; just a mild bite.

How big can the colony get?

Several thousand workers over time.

How large is the queen?

The queen measures 11-13 mm.

Is vestitus active at night?

Yes, it is a nocturnal forager that comes alive after dark.

What does it eat?

Sugar water and nectar for energy plus crickets and flies for protein.

Will it arrive alive?

Colonies ship with queen, workers, and brood plus a heat or cool pack, sent within 24 h with tracking.

Escape prevention. Coat the inner rim of every open arena with fluon (PTFE), or use talc-and-water or an oil barrier as a backup, and keep a tight, fine-mesh lid on top. Check the barrier regularly, since dust, condensation and feeding debris break a fluon line over time. Keep tubing connectors tight and seal any gaps in the nest.

Keeping reminders. Always offer fresh water and never let the nest dry out completely. Give carbohydrates continuously and protein a few times a week, and remove uneaten insect prey within 24 hours before it moulds. Keep the formicarium out of direct sunlight and away from constant vibration, which stresses a young colony. A water-filled test tube plugged with cotton makes an ideal spare incubator whenever you need one.

Before you buy – do not rehouse too early. Have a test-tube setup or a small formicarium with an outworld and a working barrier ready before your colony arrives. A founding colony grows slowly at first, which is normal. Moving a small colony into a large nest too soon invites mould, mites and stress, and the workers die off one by one. Keep the colony in its open test tube on the arena, plug the nest entrance with cotton, and open up the next chambers only once the colony fills roughly 10-15% of the space.

What we ship. Every colony ships with a live-arrival guarantee, backed by our 24h unboxing-video guarantee: if the queen does not arrive alive, we reship free. Parcels travel with DHL, InPost (PL) or EMS, with a heat or cold pack to suit the season, packed discreetly and securely. We ship across the EU and worldwide, with free shipping over the Europe threshold.
