Very large Mud Dauber nest on the side of house about 15 ft. off the ground, built around an external light fixture. Can see insects entering and leaving via entrance on front of nest. Are insects dangerous to people on ground below gardening or mowing lawn? Can the insects get into the house? How can the nest be safely removed?
They are not aggressive, in fact they are beneficial because they eat pest insects.
