Start with the route people need
Tell the assessor whether the activity is beside a front step, garage entrance, balcony, or another regularly used area. Mention whether people can avoid it safely. Observe from indoors or a distant position rather than standing under the opening. Do not attempt to provoke a reaction, move the nest, or climb closer to identify the insects for a phone conversation about service.
The structure may hide what matters
A nest hanging openly from a surface is different from insects repeatedly disappearing behind siding or into an enclosed void. Describe what is visible and what remains unknown. Do not close a suspected active opening before assessment. In a shared building, explain who controls the exterior and can authorize access, since the work may involve an area outside the unit where you first noticed activity.
Ask about access and aftercare
The proposed service should explain which nest or opening it addresses, how the work area will be accessed, and what occupants should do afterward. Confirm whether accessible nest removal is included or separate. Identification should also distinguish nesting wasps from bees or other outdoor visitors. Give details about gates, pets, and overhead obstacles so any visit can be planned around the actual property.
