Where Do Ants Go in the Winter?
Ants overwinter on a community level by hunkering down in clusters to maintain body heat, as they huddle protectively around the queen, sheltering their population's lifeline. During this time, the entrance to their nests close as ant traffic slows down and ceases. When warm weather returns, the ants will become active again, opening up the entrance to venture outside. drop dramatically and their movements become sluggish. Ants respond by seeking out warm places, such as deep soil, under rocks or under the bark of trees.
Most species of ants consume large amounts of food in the autumn to put on fat, thereby allowing them to go without much food through the winter. As winter passes, ants enter a dormant stage in which they lay low, feeding off the fats, carbohydrates and proteins they stored the previous fall.
The Awakening in Spring
The first warm days of spring lull the colony out of their dormancy, and it's back to work. Worker ants leave the nest in search of food. After they've located a food source, they eat and head directly back to the colony to alert others of the food find. Marking their return path, the worker ants lie down an odor trail leading from the food to the colony. The nesting ants then follow the odor back to the food; this explains the "ant trails" we see across the kitchen counter.
