The answer to 'why is my wasp droppings' is that wasp droppings, also known as wasp frass, are a common sign of a wasp infestation. Wasps build nests and lay eggs, and their larvae and adults produce waste that can accumulate in areas where the nest is located. This wasp frass is often found near the nest or on surfaces near where the wasps are active.
Wasp droppings can appear as small, dark stains or spots, and they may have a powdery or granular texture. The presence of wasp droppings is a clear indication that you have a wasp problem that needs to be addressed. Wasps can be aggressive and their stings can be painful, so it's important to take action to remove the nest and eliminate the infestation.
