Why Do Ants Come Out in the Winter?
WouterDuring winter months, some ants go into hibernation and others remain active. While most ant species stay inactive, there are a few ants that are scavengers.
Ants are a good example of a cold-blooded animal, and as such, they require a warm and dry shelter to survive. They typically search for a warm place to hibernate. A home may serve as such a sanctuary, especially if it is near a window.
When the weather turns cold, ants slow down, and may find shelter in a house. They may choose to huddle together in a wall or floor cavity. These areas are usually warm and dry and may even have some insulation.
Some ant species build mounds in their yard, a common place to hide from winter’s chill. They may also build a shelter under a rock.
In order to survive the winter, ants have to consume a lot of food. They consume proteins and carbohydrates to help them gain weight for the cold months ahead. Some ants will even convert their body fluids into a compound called glycerol, which helps regulate body temperature and prevents the formation of ice crystals.
When ants are confined to their nest, they need a good reason to come out. This may be a good opportunity for ants to visit the toilet, or find food. If a swarm of ants can’t find an exit, they will go into hibernation.
If you’ve seen ants around your home during the winter months, you’re likely dealing with an overwintering ant colony. This may include hundreds of ants. It’s important to clean up your home’s floors and countertops, and to make sure your pet food is sealed.
