Most people do not expect to see ants in below freezing temperatures, but many folks seemed to be plagued with ant invasions during the winter months, Why? The answer is really simple. Ants do not die out when cold weather comes. Some burrow deeper into the soil or find other places to conserve energy until temperature and humidity changes signal them to get on the move to forage. Since we have heated crawlspaces, basements and slab homes, ants can find suitable areas to survive 12 months per year along with humans. Slab home seem to have the most winter time ant problems due to the fact that a slab crates a protected environment keeping the soil warmer than than the outside soil especially if heating pipes are under the slab. During the times that ants need food for energy or protein production, they just head to our living areas to share our food and our heat.
