Camponotus laevigatus

The clean, mirror-glossy black bodies make this a smart-looking carpenter ant, and it is a gentle introduction to keeping a temperate species. Being native to western North America, it runs on a mild seasonal cycle rather than a hard freeze, so the winter break is short and undemanding instead of a deep dormancy. The workers forage mostly after dark, so evening is when the nest comes alive. Easy founding, a forgiving temperament and that light seasonal touch make it a good first step toward keeping ants that follow the year.

A temperate carpenter ant that collects sugars and honeydew for the workers and brings insect protein back for the brood. Keep a sweet feeder available and offer protein regularly through the active season, easing off around its cool rest.

Keep the founding queen in a test tube, then an ANTonTOP starter kit, and upgrade to a formicarium as worker numbers grow. This western North American ant nests in wood and runs fairly dry, so a Ytong or acrylic nest around 40-60% with one hydrated section, next to a drier arena, suits it well. Build up in stages, remembering it takes a brief cool diapause over winter, not a deep rest. Use fluon (PTFE) or talc and water on the arena rim to stop these climbers. An ANTonTOP formicarium and starter kit fit each stage.

A light winter touch is all this temperate ant asks for. The nest sits at 18-24 °C and the arena at 20-28 °C, with 40-60% humidity in the nest and 30-50% in the arena. Heat one side only so the colony can choose along a gradient. It takes a light diapause rather than a deep hibernation: give it a brief cool rest over winter, keep an eye on the colony, then return to normal temperatures in spring.

Carpenter ants grow slowly while founding and then faster as the colony establishes, building toward several thousand workers in time. The light winter rest barely interrupts the climb. You receive a laying queen with workers and brood, ready to settle into a dry-leaning nest.

• The name laevigatus means “smooth” or “polished”, matching its glossy, hairless-looking black body.
• It is a western North American carpenter ant, one of many Camponotus species across the continent.
• Rather than a hard freeze, it slows into a light dormancy over winter, in step with the milder cycle of its range.
• Like all carpenter ants it defends itself with sprayed formic acid and has no sting.

Is Camponotus laevigatus good for beginners?

Yes, it is Beginner-rated with only a light winter rest to manage.

Does this glossy black carpenter ant need a winter rest?

It takes a light diapause, a brief cool rest, not a deep hibernation.

Does Camponotus laevigatus sting or bite?

No sting, and only a mild bite.

How big can the colony get?

Several thousand workers over time.

How large is the queen?

The queen is 14-17 mm, with workers 5-10 mm and majors 10-14 mm.

How fast does it grow?

Slow at first, then steadier as the colony establishes.

What do you feed laevigatus?

Sugar water or jelly plus insects like crickets and flies.

Will the ants arrive alive?

Yes, with a heat or cool pack, dispatched 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.
