While ants don't technically hibernate, they do something very similar during the winter months. Adult ants "overwinter" and ant larvae "diapause" - a state of dormancy that conserves energy.
As temperatures drop below 50°F, ants burrow underground and enter this overwintering or diapausing state. They produce a glycerol "antifreeze" to protect their organs, lower their water content, and build up fat reserves for fuel.
However, you may still spot an ant or two indoors during winter. This could signal an overwintering colony nearby or even nesting inside your home's walls or floors. Carpenter ants are particularly fond of taking shelter in warm homes over the colder months.
If you notice multiple signs of an ant infestation, such as sawdust trails, rustling sounds in walls, or increased sightings, it's best to call a professional pest control service. Catching the problem early prevents a severe infestation when the ants emerge in spring. https://www.simplepest.com/ants/do-ants-hibernate/?utm_campaign=gbp-post&utm_medium=google&utm_source=search
