Camponotus sylvaticus

This carpenter ant ranges across Mediterranean Europe and North Africa, with the stock here from Italy, and keeping it well is mostly about respecting one firm requirement: a mandatory four-month winter rest at cool temperatures. Get that seasonal cycle right and you are rewarded with a hardy, long-running Mediterranean colony that develops good caste variation over the years. It is rated Intermediate purely for that hibernation rather than anything fiddly in daily care. A worthwhile species once you are comfortable timing a cool period and want something more involved than a year-round tropical.

This Mediterranean carpenter ant takes sugary liquids to power the workers and insect prey to grow the brood through the active season. Feeding winds down ahead of its winter rest, when the colony is dormant.

Found the queen in a test tube and upgrade once a worker force is established. This Mediterranean ant prefers the drier side, so an Ytong, acrylic, or 3D-printed formicarium kept fairly dry with a single hydrated corner fits its biology, alongside a foraging arena. It needs a mandatory winter rest at five to ten degrees, so settle the colony into a stable nest before dormancy. Treat the rim with fluon (PTFE), oil, or talc and water, as carpenter ants climb. ANTonTOP formicaria and starter kits match every stage.

Keep the nest at 20-24 °C and the arena at 20-28 °C, with humidity on the drier side that fits its Mediterranean home: nest 40-60% and arena 30-50%. Warm one end so the ants can move along a gradient. The winter rest is mandatory: a cool, dark period at 5-10 °C for 4 months every year, with feeding wound down before it begins.

Carpenter ants are slow to found, then build steadily, with the yearly rest setting the rhythm as the colony works toward up to 5,000 workers. You receive the queen with her workers and brood, ready to pick up the seasonal cycle.

• sylvaticus means ‘of the woods’, reflecting the wooded and scrubby Mediterranean country it lives in.
• It runs on a strict seasonal clock, with the annual dormancy built into its biology.
• Carpenter ants hollow out wood and cavities to nest but do not eat the material, unlike termites.
• The genus has no sting and defends the colony with formic acid, as all Formicinae do.

Is Camponotus sylvaticus good for beginners?

It is rated Intermediate, mostly because of the mandatory winter rest, so it suits keepers ready to manage a cool period.

Does Camponotus sylvaticus need a winter rest?

Yes. A winter rest at 5-10 °C for 4 months is mandatory every year.

Does this carpenter ant sting or bite?

No. It has a mild bite and no sting.

How big does the colony get?

Up to 5,000 workers under a single queen.

How large is the queen?

The queen is 14-16 mm, with workers at 5-9 mm and soldiers at 8-12 mm.

How quickly will the colony build?

Slowly at first, then steadily, with growth paced by the yearly rest.

What does it eat?

Sugar water or nectar and insects like crickets and flies; it does not take seeds.

Will it arrive alive?

Yes. It ships as a queen with workers and brood plus a season-matched heat or cool pack, within 24 hours 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.
