The answer to 'why is my wasp damage' is that you likely have an active wasp nest on or near your property. Wasps build intricate paper nests, often in attics, eaves, trees, or other sheltered areas. They can become aggressive when their nest is disturbed, leading to stings and damage from their chewing and digging behaviors.
Common signs of wasp damage include visible nests, holes or tunnels in wood, and dead wasps. Wasps may also leave behind mud tubes, paper-like debris, or other signs of their activity. If the nest is located in an area that poses a safety risk, it's best to call a professional pest control technician to safely remove it.
