MetroWest Homeowner Field Guide: Stinging Insect Activity and Nest Observation
Version 2026-08-06 · metrowestpestcontrol.com
This guide helps you document stinging-insect activity from a safe distance so the information can be reviewed by a professional. It does not identify a species, and it is not a treatment or nest-removal guide.
Do not approach, strike, spray, seal, or disturb a suspected nest for the purpose of completing this guide. Keep people and pets away from concentrated activity. Anyone experiencing a severe allergic reaction after a sting should seek emergency medical assistance.
1. Observe from a safe distance
Choose a location where you can observe activity without standing in the insects' flight path. Do not climb, open walls, move objects, touch a nest, or intentionally provoke activity.
