With their aggressive behavior, unique markings, and impressive nest-building skills, bald-faced hornets are truly remarkable insects.
Key Takeaways:
- Bald-faced hornets are wasps that closely resemble yellowjackets.
- Their nests can be as large as 14 inches in diameter.
- They are known for their aggressive behavior and smooth stingers.
- Bald-faced hornets primarily live in North America, including Idaho.
- Understanding their traits and habitat is important for coexisting with these unique insects.
Characteristics and Physical Identification of Bald-faced Hornets
Bald-faced hornets, scientifically known as Dolichovespula maculata, can be easily identified by their distinctive characteristics. They have black bodies with white-patterned faces, resembling a mask-like pattern. Additionally, they have two slanted lines on their abdomen, adding to their unique appearance.
These hornets come in various sizes, with the queen and workers ranging from 13 mm to 20 mm. The queen is the largest member in the colony. Their size and physical features make them stand out among other stinging insects.
One key characteristic of bald-faced hornets is their smooth stingers, allowing them to sting multiple times. Unlike other stinging insects, such as bees, their stingers are not barbed, giving them the ability to sting repeatedly without losing their stingers. This makes them highly capable of defending their nests and territory.
Bald-faced hornets build unique nests that are enclosed and constructed from wood fibers mixed with their saliva, creating a gray, paper-like material. These nests can be impressive in size, reaching up to 14 inches in diameter. The shape of their nests often resembles an inverted teardrop.

Bald-faced Hornet Habits and Behaviors
Bald-faced hornets are social insects that live in colonies. They exhibit specific behaviors and habits that contribute to their survival and success as a species.
These hornets are most active during the day, engaging in various activities within their colonies. A typical bald-faced hornet colony can consist of anywhere from 100 to 400 members at its peak.
In late summer, when populations are largest, males emerge from unfertilized eggs. Their primary purpose is to inseminate the new females for the next generation. Meanwhile, the remaining members of the nest, including the workers and old queen, die off.
The inseminated females, or potential queens, overwinter by finding protected places to hibernate until the following spring. Once spring arrives, they begin the process of building new nests and establishing new colonies.
Unlike some other stinging insects, bald-faced hornets do not reuse their nests season after season. Instead, they construct new nests each time, showcasing their architectural prowess and adaptability.
Regarding their diet, bald-faced hornets primarily feed on protein sources during the early spring and summer months. They actively hunt live prey such as insects, spiders, and other small invertebrates. As the seasons progress and food sources become scarcer, they switch their diet to nectar, fruit juices, and other carbohydrates.
Behaviors and Habits Summary:
- Social insects that live in colonies
- Most active during the day
- Males inseminate the new females at the end of summer
- Remaining members of the nest die off
- Inseminated females overwinter to start new colonies
- Construct new nests each time
- Feed on protein sources in the early spring and summer
- Later switch to nectar and carbohydrates
Understanding the habits and behaviors of bald-faced hornets is crucial to coexisting with them and appreciating their role in the ecosystem.
Bald-faced Hornet Habitat and Distribution
Bald-faced hornets, scientifically known as Dolichovespula maculata, are social insects that build their nests at least three feet off the ground. They prefer nesting in trees, shrubs, or on various structures such as utility poles, houses, and sheds. These aerial nests, typically grey in color, are enclosed and can reach impressive dimensions, measuring up to 24 inches in height and 18 inches across.
When considering the bald-faced hornet distribution, these insects are primarily found in North America, including Idaho. They can be encountered throughout the 48 contiguous states, as well as in Alaska and Canada. Their adaptability allows them to establish nests in diverse geographical locations, from wooded areas to urban environments.
The bald-faced hornets’ choice of nesting sites plays a crucial role in their survival and reproduction. By selecting elevated locations, they are protecting their colonies from potential predators and minimizing the risk of their nests being damaged by ground-dwelling animals. This behavior also aids in creating a safe and secure space for raising their developing young.
Understanding the bald-faced hornet habitat and distribution is essential for effective pest management and safety precautions. Identifying the locations where these hornets tend to build their nests can help homeowners and professionals alike in effectively removing and controlling populations when necessary.

Bald-faced Hornet Sting and Potential Risks
Bald-faced hornet stings can cause pain, itching, and swelling for approximately 24 hours. The venom injected during a sting can elicit an uncomfortable reaction in individuals who are not allergic to it. However, those who are allergic to insect stings, such as wasp or bee stings, are at increased risk of experiencing severe reactions to a bald-faced hornet sting.
Bald-faced hornets are known for their aggressive nature and their tendency to defend their nests fiercely. They will attack anyone or anything that they perceive as a threat to their colony or territory. When a bald-faced hornet stings, it can do so repeatedly due to its smooth stinger, which does not remain lodged in the victim’s skin like other stinging insects.
Given their aggressive behavior and the potential risks associated with their stings, it is recommended to seek professional assistance for bald-faced hornet nest removal. Attempting to remove a nest without the proper knowledge and equipment can result in multiple stings and potentially dangerous situations.
To prevent bald-faced hornet stings, it is important to avoid contact with these insects and their nests. Be cautious when spending time outdoors, especially in areas where hornets are known to build their nests. If a bald-faced hornet nest is located near your home or in close proximity to areas where people gather, it is advisable to have it removed by licensed pest management professionals.
