Welcome to What’s Bugging You!

Our goal is to help you identify, understand and, where needed, safely manage the critters found in and around your home, garden, school, places of work and worship. Use of the word “critter” is intentional; not all things that buzz, crawl or slither are pests! Some insects may be pollinators that play an important role in the ecosystem, and some animals can help reduce the numbers of ticks and other pests in your yard.

This page is designed to help you identify your critter by choosing one of the sections below. If you know what type of critter you have, you can select it from the list of pest categories in the left sidebar. If you are not sure, you can either select the location where you found it, or the time of year it was discovered. For arthropods (insects, spiders, etc.), you can also try the Pest Identification Key or Quick ID Guide.

Choose the room in your house that needs pest management
