How do you find a European hornets nest?

To find a European hornets' nest, look for their characteristic large, paper-like nests, often hidden in tree cavities, shrubs, or attics. Observe their flight patterns; hornets tend to fly in and out of a specific area. Additionally, listen for their buzzing sounds, especially in late summer or early fall when nests are most active. Always exercise caution and consider contacting a professional if you locate a nest, as these insects can be aggressive when threatened.
