We often don’t think about carpenter ants in the cold wet months but they still exist and continue their never ending destruction of your house. Their role in the environment is waste processors as they tunnel through dead plants, trees and soil, aerating it. Regrettably, these ants see our homes as piles of sticks that they can covert into their satellite nests. Ants are the most damaging wood destroying insects in the lower mainland and they are active 24/7 365. When the temperatures drop, most outdoor carpenter ants hibernate and remain dormant during the colder months but the ones in your walls continue to burrow through wood, feed the larvae, and maintain the satellite nest in your walls.
