Behavior
Bald-faced Hornets are eusocial wasps that live in complex colonies centered around a single queen. They are renowned for their architectural skills, constructing large, pear-shaped nests made of chewed wood fibers mixed with saliva, which creates a durable grey paper. These nests are typically found hanging from tree branches or building eaves. While they are often feared for their sting, they are generally focused on colony maintenance and foraging unless their nest is directly disturbed.
Within the colony, there is a clear division of labor. Workers spend their days hunting for protein to feed the developing larvae and gathering nectar for their own energy. They are highly intelligent navigators and possess a sophisticated communication system. Interestingly, they are one of the few wasp species that can squirt venom from their stingers into the eyes of vertebrate intruders, making them formidable defenders of their home.

Camera Tips
To capture high-quality footage of Bald-faced Hornets, focus your camera on foraging hotspots rather than just the nest. They are particularly attracted to late-summer blooms like goldenrod, sedum, and aster. Position your camera about 24 to 36 inches away from these flowers. Because these insects move with incredible speed, use a camera with a fast trigger speed and high-frame-rate video settings to avoid a blurry image. Mid-morning light is ideal, as the bright sun helps illuminate the white facial markings against their dark bodies.
If you have located a nest and wish to monitor it, safety is paramount. Never mount a camera directly to the branch holding the nest, as the vibrations will alert the colony. Instead, use a tripod or mount the camera on a nearby structure at least 10-15 feet away. Use a telephoto or zoom lens to get a close-up view of the entrance hole, which is usually located at the bottom of the structure. This is the best place to see workers bringing back 'meat balls' of chewed insects for the larvae.
In late summer, you can lure them into the camera's view by placing a small dish of sugar water or overripe fruit like peaches or grapes in a sunny spot. This is especially effective in September when the colony is at its peak size and the demand for energy is high. If you are using an AI-powered camera, ensure the 'Insect' or 'Small Animal' detection setting is active, and try to keep the background simple to help the AI focus on the hornet's high-contrast markings.
