Are European Paper Wasps Aggressive and How to Handle Infestations

European paper wasps are generally not aggressive, but they can become defensive if their nest is threatened. They're known to be relatively docile and non-threatening, especially during the day.

European paper wasps build umbrella-shaped nests, typically in protected areas like eaves, attics, or under roof overhangs. These nests can be quite large, with some colonies having up to 20,000 individual wasps.

If you encounter a European paper wasp nest, it's essential to exercise caution and not approach it. A single wasp can deliver a painful sting, and multiple stings can be more serious, especially for people with allergies.

European paper wasps are typically active during the warmer months, from spring to fall, and are most active during the late afternoon and early evening.
