Care Guide
Camponotus gigas, the giant forest ant, is one of the largest ant species in the world and a true spectacle for experienced keepers. These ants display pronounced size variation within a single colony: the queen, a magnificent individual measuring 20 to 28 mm, is the heart of the nest. Workers range from 10 mm minors to formidable 22 mm majors, whose powerful mandibles are built for hunting and defense. Watching these oversized ants move through their territory is an unforgettable experience.
Their diet is rich and varied. In the wild, Camponotus gigas are active predators and scavengers, feeding on insects, honeydew, and other sugary secretions. In captivity, they thrive on a mix of live or pre‑killed insects—crickets, roaches, mealworms—along with sugar water or diluted honey. They are particularly fond of liquid sugars and will eagerly collect honeydew if offered. A growing colony of this size consumes a surprising amount of protein and carbohydrates, so regular, generous feeding is essential.
Care difficulty
Keeping Camponotus gigas is considered advanced. Their large size, rapid growth, and environmental demands require a dedicated keeper. Stable temperatures between 24 and 28°C and high humidity levels of 70 to 90 percent are crucial—without adequate moisture, brood development suffers and the colony may decline. This species does not hibernate, allowing year‑round activity but also meaning you must maintain conditions consistently. Founding is claustral, so the queen can start in a test tube setup, but the colony will quickly outgrow it, demanding a spacious formicarium well before the first workers appear.
Housing
A large, well‑designed formicarium with an attached outworld is necessary. The nest itself should offer chambers tall and wide enough to accommodate the ants’ size and their numerous brood. Use a substrate that retains moisture, such as a sand‑clay mix or hydrostone, to maintain the required humidity. Ventilation is important to prevent mold, but avoid drafts. The outworld must be escape‑proof; these ants are capable climbers and can squeeze through small gaps. Provide a heat cable or mat on one side of the nest to create a thermal gradient. Camponotus gigas are somewhat sensitive to vibrations and disturbances, so place the setup in a quiet, low‑traffic area.
First days after purchase
After receiving your colony, transfer them gently into their new home and allow several days of complete calm. Minimize opening the nest or tapping the glass. Ensure constant access to fresh water (via a test tube or water tower) and offer small amounts of sugar water and a single insect. Observe from a distance; if the queen begins laying eggs and workers are foraging, the colony is settling in. Avoid feeding large prey until they are fully acclimated. Patience is key—this species rewards diligent keepers with a spectacular, long‑lived colony that becomes the centerpiece of any ant room.
