The Bald Faced Hornet, also known as Vespula maculata, is a species of wasp that belongs to the Vespidae family. These insects are known for their distinctive white and black coloration, as well as their large, exposed nests. Bald Faced Hornets are found throughout much of North America, and are a common sight in many backyards and gardens. Despite their fearsome reputation, these wasps play an important role in the ecosystem, and are actually beneficial to have around.
One of the most interesting things about Bald Faced Hornets is their social structure. These wasps live in colonies, with a single queen at the helm. The queen is responsible for laying eggs, while the worker wasps - which are all female - take care of the young, forage for food, and defend the nest. Male wasps, on the other hand, have only one purpose: to mate with the queen. This social hierarchy is fascinating to observe, and is a key aspect of the Bald Faced Hornet's biology.

Bald Faced Hornet Nests
Bald Faced Hornet nests are one of the most distinctive features of these wasps. The nests are typically gray or brown in color, and are made of a paper-like material that the wasps produce from their saliva. The nests are usually shaped like a teardrop, and can grow to be quite large - up to 2 feet in length and 1 foot in width. The nests are also exposed, meaning that they are not hidden in a protected location like a hollow tree or a rock crevice. This exposed location allows the wasps to defend their nest more easily, and also helps to regulate the temperature inside the nest.
The nests of Bald Faced Hornets are also incredibly complex, with a intricate network of cells and tunnels. The wasps use these cells to store food and raise their young, and the tunnels provide a way for the wasps to move around the nest. The nests are also remarkably strong, and can withstand a significant amount of wind and rain. This is due in part to the fact that the wasps use a combination of saliva and plant material to construct the nest, which provides a strong and durable structure.
Bald Faced Hornet Behavior
Bald Faced Hornets are known for their aggressive behavior, particularly when they feel threatened or when their nest is disturbed. These wasps are capable of delivering a painful sting, and will not hesitate to do so if they feel that their colony is in danger. However, it’s worth noting that Bald Faced Hornets are generally not aggressive towards humans, and will only attack if they are provoked. In fact, these wasps are actually quite beneficial to have around, as they help to control pest populations and pollinate plants.
One of the most interesting things about Bald Faced Hornet behavior is their communication methods. These wasps use a variety of signals to communicate with each other, including pheromones, body language, and even sound. For example, when a forager wasp returns to the nest with food, it will perform a complex dance to communicate the location of the food source to its fellow wasps. This dance involves a series of movements and postures, and is an essential part of the wasps' social behavior.
| Characteristics | Description |
|---|---|
| Coloration | Distinctive white and black markings |
| Nest shape | Teardrop-shaped, exposed nest |
| Nest material | Paper-like material produced from saliva |
| Colony size | Up to 700 workers and a single queen |
| Diet | Primarily insects and spiders, as well as nectar and pollen |
Bald Faced Hornet Stings
Bald Faced Hornet stings are a serious concern for many people, particularly those who are allergic to wasp venom. These stings can be painful and even life-threatening, and should be treated with caution. However, it’s worth noting that Bald Faced Hornets are generally not aggressive towards humans, and will only sting if they feel threatened or if their nest is disturbed.
If you are stung by a Bald Faced Hornet, it's essential to seek medical attention immediately. The symptoms of a wasp sting can range from mild to severe, and may include redness, swelling, and pain at the site of the sting. In severe cases, a wasp sting can cause anaphylaxis, a life-threatening allergic reaction that requires immediate medical attention.
Preventing Bald Faced Hornet Infestations
Preventing Bald Faced Hornet infestations is an important part of maintaining a safe and healthy outdoor space. There are several steps you can take to prevent these wasps from nesting on your property, including removing food sources, sealing entry points, and using repellents. It’s also essential to be aware of the signs of a Bald Faced Hornet infestation, such as the presence of a nest or the sighting of individual wasps.
One of the most effective ways to prevent Bald Faced Hornet infestations is to remove food sources. These wasps are attracted to sweet or fermented substances, such as soda, juice, and fruit. By removing these substances from your outdoor space, you can help to discourage Bald Faced Hornets from nesting on your property. You can also use repellents, such as citronella or lemongrass, to help deter these wasps.
