Why do spider webs keep returning around exterior lights, eaves or porches?
Webs can return because a sheltered spot continues to provide prey and places to attach silk. Exterior lights can attract insects, which in turn provide food for spiders. Removing a web does not necessarily change those conditions.
For this property, first record where webs return and how quickly Then ask the reviewing professional can lighting placement or timing reduce insect concentration? Keep the decision tied to the observed condition instead of treating this general guidance as a diagnosis.
Stop before the situation becomes unsafeDo not handle an unidentified spider or work on an energized exterior fixture.
