Swarmers gather at a porch light in May
- What homeowners notice
- Winged insects collect at a porch fixture each evening in May, and wings are found on the step and the sill the next morning. The homeowner keeps a few wings in a sealed container and notes the dates.
- What we do
- The inspection follows the trail from the light to the foundation, checks the soil line and the entry points at the door, and then looks at the trees and any stump in the yard. The light is changed to a timer that turns off after dusk for the rest of the swarm window.
- What to expect
- The written record lists the places checked, the findings and the follow-up date in late June, and the homeowner keeps the dated wings and photographs with the house papers.
