How Can Ants Live in Cold Weather?
WouterGenerally, ants don’t like the cold, but they are not without survival strategies. While many species of ants huddle deep underground, others form colonies under rocks or wood in the winter. These colonies use the rock heat to sustain their colony until spring.
When temperatures fall below 50 degrees Fahrenheit, ants’ bodies slow down their metabolic rate. This process is known as diapause. They enter a dormant state and store an extra layer of fat below their skin for warmth. Some species of ants also convert their body fluids to glycerol to help regulate their body temperatures. This prevents the formation of ice crystals in their bodies.
When it gets cold, ants will move in groups to warm areas. They can also hide inside homes and appliances to keep themselves warm.
Some ants will build a mound of dirt over their colony to absorb radiant heat from the sun. They will also close off entryways to their mounds during cold weather. They will also search for food sources. Some will build elaborate tunnel systems to reach the food sources. These tunnels help retain body heat and provide protection.
When the temperature rises, ants will begin to emerge from their hideouts. They will then search for food and water sources. They may also move to a different location if they don’t find what they need.
When the temperature goes below 75 degrees Fahrenheit, ants will retreat to their group warmth. This may be their main colony or a satellite colony that is located inside the home. They may also hibernate until warmer temperatures return.
