Farm and colony growth

Carpenter ants readily live in cork, wood, gypsum or aerated concrete nests. Workers are good climbers and look for gaps, so use a tight lid and an anti-escape barrier on the arena walls. The queen founds the colony alone and does not eat until the first workers appear; the first workers are small, and majors appear once the colony grows.
