An enclosed paper nest, an open comb and insects entering soil are different observations. None is a reason to approach or disturb the nest to make a diagnosis.
Enclosed aerial nest
A gray paper enclosure in a tree or on a building can be consistent with a social wasp nest. Black-and-white bald-faced hornets are one possibility. Describe its attachment point and the activity around it. Our bald-faced hornet removal page focuses on access and scope.
Open, umbrella-shaped comb
Exposed cells without a surrounding paper envelope are a useful clue for paper wasps. Explain whether the comb is near a door or attached to something people move. The paper wasp guide discusses proportional assessment and everyday contact.
Traffic into a wall or ground opening
Repeated entry into one point may indicate a concealed colony, but the opening alone cannot identify it. For a structure, review yellow jacket nest questions. For soil activity, use the ground nest assessment guide and mention whether there are multiple burrows.
Why identification matters
Bees and wasps have useful ecological roles, and not all activity needs treatment. A provider should consider the insect, the likelihood of contact and the actual property conditions. Ask what makes the recommended action appropriate rather than assuming every flying insect requires removal.
How to describe the situation
Useful details include the entrance location, an approximate height observed from the ground, nearby occupied spaces and whether anyone has disturbed the nest. A clear description is enough to begin an inquiry. You do not need to collect a specimen or improve a photograph by moving closer.
