The answer to 'carpenter ant droppings' is that carpenter ants leave behind small piles of sawdust-like droppings as they tunnel through wood. These droppings are a common sign of a carpenter ant infestation in your home. Carpenter ants don't actually eat the wood, but they hollow it out to create nests, which can lead to structural damage over time.
If you notice carpenter ant droppings, it's important to address the issue promptly. Small infestations can often be treated with DIY methods like baits or sprays, but larger infestations may require professional pest control services to fully eliminate the colony and prevent further damage.
