Camponotus herculeanus

This is a hardy native giant from the Holarctic north, built for cool conditions and a deep hibernation rather than tropical heat, so it suits a keeper who wants something that lives on a real seasonal cycle. What stands out is patience: the queen can live well over a decade, making this a long-term project rather than a quick build. It carves galleries in damp wood in the wild, and the colony grows slowly but steadily. Keep it cool, run the winter rest carefully, and you have a long-running native colony that few tropical species can match for longevity.

A cold-climate carpenter ant that gathers honeydew and tree sap for sugars and hunts insects to feed the brood through the short northern season. Keep a sweet source available and offer protein regularly while the colony is active, stopping over the winter rest.

Start the founding queen in a test tube, then move to a Ytong or acrylic formicarium as this long-lived species slowly builds toward several thousand workers. It tunnels into wood in cool northern forests, so keep one nest area damp near 50-70% and never let the chamber run hot. Build up gradually and plan around the deep November to March winter rest. Fit the outworld with a fluon (PTFE) or talc-and-water barrier. An ANTonTOP formicarium and starter kit suit this patient species from founding.

This is a cool-running species, not a tropical one, so keep temperatures modest: nest 18-22 °C and arena 18-26 °C, with 50-70% humidity in the nest and 30-50% in the arena. Warm only one end of the arena to make a gentle gradient; the nest should never get hot. A full winter rest is required from November to March at around 5-10 °C, with feeding stopped through the dormant months.

Growth is slow, with eggs taking roughly eight to ten weeks to reach worker stage, so this is a patient build toward as many as 5,000 workers. The reward is a queen that can live 10-15 years and a colony that lasts. You receive a laying queen with workers and brood, ready to establish at cool temperatures.

• Linnaeus named this ant in 1758, as Formica herculeana, placing it among the earliest ants formally described in science.
• It ranges right across the Holarctic, through the conifer forests of northern Europe, Asia and North America.
• Colonies excavate extensive galleries in standing and fallen conifer wood, which is why the species can turn up as a minor structural pest.
• As a boreal ant it overwinters by going fully dormant in the cold, one of the most northerly carpenter ants there is.

Is Camponotus herculeanus good for beginners?

It is Intermediate, easy to found, but it needs cool keeping and a full winter hibernation.

Does this giant forest carpenter ant need a winter rest?

Yes, from Nov to Mar at around 5-10 °C with feeding stopped.

Does Camponotus herculeanus sting or bite?

No sting; only a mild bite.

How big does the colony get?

Up to 5,000 workers.

How large is the queen?

The queen is 16-18 mm, with workers 8-12 mm and majors 11-15 mm.

How long does this carpenter ant live and grow?

Slowly, as eggs take about 8-10 weeks, but the queen lives 10-15 years.

What does it eat?

Sugar water or nectar plus insects such as crickets and flies.

Will the ants arrive alive?

Yes. Queen, workers and brood ship with 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.
