They live in colonies not exceeding 50 insects. Naturally they nest in tunnels on the ground or build wax nests on grass. They also build their nests under roof beams and attics. They will aggressively defend their nests through multiple stinging.
These insects can be found both in the forest and residential areas. They bore on dry wood and create tunnels where they lay their eggs and nurse their larvae. These tunnels can be a few inches to a more than a foot long.
