How do you remove residue from a wasp nest on your house?

To remove residue from a wasp nest on your house, first ensure the area is safe by wearing protective clothing and using a pesticide specifically designed for wasps. Once the nest is dealt with, use a mixture of soap and water to scrub the residue off the surface. For stubborn spots, a vinegar solution can help break down the residue. Rinse the area with water after cleaning to eliminate any remaining substances.
