The answer to 'ant trails' is that ant trails are a common sign of an ant infestation in your home. Ants leave pheromone trails to mark the path from their nest to a food source, which can lead them straight into your home. Some common causes of ant trails include crumbs, spills, or other food sources that attract them indoors.
The symptoms of an ant infestation include seeing ants in your home, following a visible trail, or finding the nest. To solve the problem, you'll need to eliminate the food source, seal entry points, and potentially use ant baits or sprays. For severe or recurring infestations, it's best to call a professional pest control technician who can properly identify the ant species and treat the problem effectively.
