ABOUT THE GUIDE
Observe first. Identify with care.
Pest Evidence Guide is an independent reference for visible household pest signs in US homes. It helps readers record what they found, compare lookalikes, and find a reliable source before taking action.
What you will find here
Guides start with observable evidence: droppings, wood marks, egg cases, larvae, stains, or winged insects. Each page explains the limits of a visual identification and links to public agency or university extension material. Browse by clue, pest, or search the guide directory.
Use the reference as a working kit
Start with a visible clue, compare the features in a guide, and keep the location and date in your evidence log. The printable toolkits help you prepare an observation record, while the glossary explains unfamiliar terms. Our resource hub connects those steps with further reading and identification help.
What a web guide can tell you
A photo or single sign may narrow the possibilities, but it cannot confirm an infestation, its extent, or whether activity is current. For structural damage, recurring signs, or uncertainty, contact a licensed local pest professional. For rodent droppings, follow the linked CDC cleanup instructions.
How we handle sources and corrections
We cite the source used for each guide and show when it was checked. Read the editorial policy for our review process. The contact page identifies the temporary contact setup for this build.
