How to feed Camponotus

Camponotus are large ants, often active at night. They grow slowly at first, then their needs rise quickly.

How much to feed

Guidelines for a colony with a moderate amount of brood, at 22–28 °C (72–82 °F):

WORKERSPROTEINSUGAR / 3–4 DAYS
10 (Nanitics)1 prey item every 5 days1 drop
50 (Small)5 prey items every 4 days2 drops
150 (Growing)16 prey items every 3 days7 drops
400 (Established)40 prey items every 3 days18 drops

1 prey item = one insect the size of a fruit fly (2–3 mm). A medium cricket (1 cm) is worth about 50 prey items. 1 drop ≈ 0.05 mL.

These are starting points. If food is left after 24 h, give less; if everything disappears fast and the brood grows, give more. The calculator also adjusts for brood and temperature.

Hibernation

Northern and central European species (C. ligniperda, C. vagus): November to March, 5–10 °C. Mediterranean species (C. cruentatus, C. barbaricus): light hibernation December to February, 10–12 °C. Tropical species (C. nicobarensis…) must not be hibernated. North American species such as C. pennsylvanicus need a temperate hibernation too.

FAQ

Do carpenter ants eat wood?

No. They dig into wood to nest but do not eat it.

How often should I feed Camponotus?

Protein every 3 to 5 days, sugar at all times.

Why is my Camponotus colony growing so slowly?

It is typical of the genus: the first year often ends with fewer than 20 workers.

Amounts and timings are average guidelines, not rules. Always adjust to what you see in your own colony (leftovers, appetite, brood).
