Exploring Common Types of Wasps in North America
Welcome to this guide where we will explore the common types of wasps found in North America, providing you with valuable identification tips and essential information about these fascinating creatures.
Key Takeaways:
- There are various types of wasps in North America, including yellow jackets, European hornets, baldfaced hornets, paper wasps, and solitary wasps.
- Yellow jackets are often mistaken for bees due to their black-and-yellow striped appearance, but they are smooth and have a thin waist. They can be very aggressive and dangerous.
- European hornets resemble yellow jackets but nest in cavities and can forage during the day or night. They are not aggressive unless disturbed.
- Baldfaced hornets are not actually hornets but wasps. They have distinctive black and white markings and build large nests high in trees. They are generally not aggressive unless their nest is threatened.
- Paper wasps are known for their small nests made of a paper-like substance. They come in a range of colors and can be beneficial for pest control.
- Solitary wasps belong to different families and are non-aggressive. They play an important role in controlling insect populations.
The Wasp Family
Before we delve into the specific types of wasps found in North America, let’s take a closer look at the fascinating world of the wasp family and their unique characteristics.
- Wasps are an entirely different species from bees. They are carnivores who live off of other small creatures, mostly insects, using this protein to feed their young.
- Unlike bees, many types of wasps do sting and can be very aggressive. The ability to sting multiple times without harming themselves, and to send out alarm pheromones quickly bringing more wasps to the scene, means that they can be quite dangerous to humans.
The wasp family includes various species that can be found in North America. Let’s explore some common types that are frequently mistaken for bees in the United States.
Yellow jackets
Yellow jackets are commonly mistaken for bees because of their striped black-and-yellow markings. The major difference is that yellow jackets are smooth—never fuzzy or hairy like bees—and their yellow stripes tend to be brighter and shinier. They also have a thin, “wasp” waist.
Yellow jackets mostly live in the ground (old rodent burrows are common homes) or sometimes in stone walls and are very protective of their colony, often attacking if a person approaches even within a few feet of their nest or if a lawn mower makes a nearby sound or vibration. Unfortunately, individual colonies can contain thousands of wasps which will swarm out of the nest when alarmed, making them very dangerous to humans and their pets. If you see yellow jackets flying in and out of a hole in your backyard, it’s best to get professional help.
Note: Yellow jackets can become more problematic in late summer and early fall, as they start to crave more sugar and their normal sources of food become scarce. This is often when you can find them lurking around picnics and garbage cans. Put lids on your trash cans and cover your sugary drinks!
European hornets
Hornets are a member of the wasp family not native to North America, but the European hornet can now be found throughout large parts of the United States, from the east coast to the Dakotas. With smooth, striped, black-and-yellow bodies, these insects look very similar to yellow jackets, making it hard to tell them apart. They differ from yellow jackets in that they usually nest in cavities at least six feet off the ground, such as the hollow of a tree, and never in the ground. Unlike yellow jackets, European hornets will forage during the day or night, meaning that you can sometimes find them bumping off of porch lights.
Unlike yellow jackets, these hornets are not aggressive unless disturbed, so leaving them alone is usually the best practice. However, if you have a European hornets nest in the exterior of your house, you should seek professional help. Do not block their entrances, as they can chew through wood to find another exit into your living space—making your problem much, much worse.
Baldfaced hornets
To make insect identification even more confusing, baldfaced hornets are not actually hornets, but wasps (the only true hornets in the U.S. are the European hornets mentioned above). Their name derives from their facial markings, which are white and black (the black and white markings extend along their abdomen, as well). These stinging insects like to build their nests high in trees, wrapping layers of a paper-like substance into a large football shape that can be two-feet long. Since each nest is only used for one season, you can often find old, empty nests slowly disintegrating in the forest.
While the incredible size of a baldfaced hornet nest makes people alarmed, these insects are not usually aggressive unless you come within a few feet of their nest. If you see a nest in a shrub in your yard, or in another high-trafficked area, you should seek professional help. Otherwise, these wasps are best left in peace.
Paper wasps
Paper wasps are known for their small, paper-like nests hanging from a single stalk and often found under porch railings, in the eaves of picnic shelters, and in other protected spaces. These wasps come in a range of colors, including orange, red-brown, burgundy, and even some with black and yellow stripes. Once again, the primary difference between paper wasps and bees is that wasps are always smooth, and never fuzzy or hairy.
The good news is that these wasps tend to be less aggressive, their colonies are fairly small, and they will not usually sting unless provoked. The biggest danger for humans is accidentally disturbing a colony, as they like to build their nests in human-created structures. Surprisingly, while these wasps are not terrific pollinators, they can actually help with both gardening and pollination, as they sometimes eat nectar and spread pollen, and since they frequently dine on caterpillars and other pests that can hurt your crops. Bottom line? If you see a paper wasp nest in an out-of-the-way place, you might decide to just let it be.
Solitary Wasps
While the social wasps mentioned above form colonies, there are also solitary wasps that lead independent lives. These solitary wasps are important predators of other insects and play a crucial role in controlling insect populations. They belong to different families and have their own unique hunting behaviors.
Overall, the wasp family is diverse and fascinating, with a wide range of species found throughout North America. Understanding the different types of wasps can help us coexist with these insects and appreciate their contributions to our ecosystems.
Yellow Jackets
One of the most commonly mistaken wasp species for bees in North America is the yellow jacket, known for its bright black-and-yellow striped markings and aggressive nature. Yellow jackets are smooth and never fuzzy or hairy like bees. They have a thin, “wasp” waist and their yellow stripes tend to be brighter and shinier. These wasps mostly live in the ground, often in old rodent burrows, or in stone walls. They are very protective of their colonies and will attack if a person approaches within a few feet of their nest or if there is a loud sound or vibration nearby, such as from a lawn mower.
Individual yellow jacket colonies can contain thousands of wasps, and when alarmed, they can swarm out of the nest, making them very dangerous to humans and pets. If you notice yellow jackets flying in and out of a hole in your backyard, it is best to seek professional help to remove the nest.
Note: Yellow jackets can become more problematic in late summer and early fall when they start to crave more sugar and their normal sources of food become scarce. This is often when you can find them lurking around picnics and garbage cans. To avoid attracting them, make sure to put lids on your trash cans and cover your sugary drinks.

Baldfaced Hornets
Baldfaced hornets, despite their misleading name, are a species of wasps commonly found in North America, known for their unique black and white facial markings and impressive nest-building skills. These stinging insects are not actually hornets, but rather a type of wasp belonging to the family Vespidae. They are easily identifiable by their distinctive appearance, with their black body and white markings on their face, thorax, and abdomen.
Nest-Building Behavior
Baldfaced hornets are skilled builders and create large, football-shaped nests that can measure up to two feet in length. These nests are constructed with a paper-like substance made from chewed wood fibers mixed with their saliva. The nests are typically attached to tree branches, shrubs, or other elevated surfaces, providing protection and stability for the colony.
Temperament Towards Humans
While baldfaced hornets have a fearsome appearance, they are generally not aggressive unless their nest is threatened. They will typically only sting humans in self-defense, such as when they feel their nest or their own safety is at risk. However, it’s important to exercise caution and avoid provoking these wasps, as their stings can be painful and cause allergic reactions in some individuals.

Seeking Professional Help
If you come across a baldfaced hornet nest in close proximity to your living space or areas with high human activity, it is advisable to seek professional help for removal. Attempting to remove the nest yourself can be dangerous and may lead to stings and injury. Pest control experts have the necessary equipment and expertise to safely remove the nest and minimize the risk to both you and the environment.
Benefits and Role in Ecosystem
Baldfaced hornets play an important role in the ecosystem as predators of other insects. They help control population levels of flies, caterpillars, and other pests that can damage crops and gardens. Additionally, they contribute to the pollination of plants as they feed on nectar and inadvertently transfer pollen between flowers.
Conclusion
In conclusion, baldfaced hornets are a common type of wasp found in North America, known for their distinct black and white facial markings and skill in nest-building. While they may appear intimidating, they are typically not aggressive unless provoked. It is best to seek professional help for the removal of their nests to ensure safety. Baldfaced hornets serve an important ecological role as predators of pests and contribute to the pollination of plants.
Paper Wasps
Paper wasps, known for their paper-like nests and diverse color patterns, are a common type of wasp species found in North America with interesting ecological benefits. These wasps are part of the Vespidae family, which includes other social wasps like yellow jackets and hornets. Paper wasps are typically between 0.5 to 1 inch in length and have a slender body with long, narrow wings.
Nest Building and Behavior
One of the most distinctive features of paper wasps is their nest-building behavior. They construct nests using a papery substance made from wood pulp mixed with their saliva. These nests can be found hanging from various structures, such as tree branches, eaves of buildings, or even outdoor furniture.
Unlike yellow jackets and hornets, paper wasps are generally less aggressive and will only sting if they feel threatened or their nest is disturbed. They are known for being territorial and will defend their nest by stinging intruders. However, they are unlikely to become aggressive unless provoked.
Color Patterns and Identification
One of the interesting aspects of paper wasps is their diverse range of color patterns. While many species have a combination of black, yellow, and orange or red markings, some may have more unique coloration, such as metallic blues or iridescent greens. This variation in color can make paper wasps visually appealing.
Identifying paper wasps can be challenging as their appearance can overlap with other species. However, there are a few key characteristics to look for. Paper wasps have a slender body with a distinct “wasp waist” and elongated legs. Unlike bees, they are not hairy or fuzzy, and their body shape is more elongated.
Ecological Benefits
While paper wasps may be seen as a nuisance by some, they actually provide important ecological benefits. These wasps are effective predators, primarily feeding on insects such as caterpillars, beetles, flies, and spiders. This makes them valuable for natural pest control in gardens and agricultural settings, helping to keep pest populations in check.
Coexistence and Nest Removal
It is generally recommended to coexist with paper wasps unless their nest poses a direct threat to human activity or safety. If a paper wasp nest is located in an area of high human traffic or poses a risk, it is advisable to seek professional help for safe removal. Attempting to remove a nest without proper training and equipment can be dangerous.
In conclusion, paper wasps are common in North America and have diverse color patterns and interesting nest-building behavior. While they can sting if threatened, they provide ecological benefits by controlling pest populations. If their nest poses a risk, professional help should be sought for safe removal.
Solitary Wasps
In addition to social wasp species, North America is also home to various solitary wasps, which play a crucial role in pest control and exhibit fascinating solitary hunting behaviors.
Thread-Waisted Wasps (Family Sphecidae)
Thread-waisted wasps are a diverse group of solitary wasps that are known for their distinctive thin waist. They are often seen flying low to the ground, hunting for prey. These wasps build nests in the ground or in preexisting cavities, such as old beetle burrows or hollow plant stems. Once they have captured their prey, which can range from spiders to caterpillars, they paralyze it with their venom and carry it back to their nest to serve as a food source for their offspring.
Cuckoo Wasps (Family Chrysididae)
Cuckoo wasps are small, colorful wasps that are known for their shiny metallic appearance. These wasps are parasites, laying their eggs in the nests of other wasp species. When the cuckoo wasp larva hatches, it consumes the host wasp’s eggs or larvae. Despite their parasitic nature, cuckoo wasps are generally harmless to humans and are beneficial in controlling populations of other wasp species.
Potter Wasps (Subfamily Eumeninae)
Potter wasps are named for their habit of building nests that resemble small pottery vessels. They construct these nests out of mud or clay, using their saliva as an adhesive. The female potter wasp provisions each cell of her nest with a paralyzed prey item, such as a caterpillar or beetle, before laying her eggs. Once the eggs hatch, the larvae feed on the paralyzed prey.
Velvet Ants (Family Mutillidae)
Despite their name, velvet ants are actually wasps. These solitary wasps are known for their fuzzy appearance, which resembles that of ants. The females do not have wings and are often brightly colored, while the males have wings and are more wasp-like in appearance. Velvet ants are known for their painful sting and should be handled with caution, although they are generally not aggressive unless provoked.
“Solitary wasps play a crucial role in pest control, as they help keep populations of other insects in check. Their solitary hunting behaviors are fascinating to observe and highlight the diversity of wasps in North America.” – Entomology Expert
It is important to note that while solitary wasps can be beneficial, some species may pose a threat if their nests are disturbed or if they feel threatened. It is best to observe them from a distance and avoid provoking them. If you are experiencing issues with wasps on your property, it is recommended to consult with a professional pest control service for safe and effective removal.
Understanding the Common Types of Wasps in North America
Understanding the common types of wasps found in North America is essential for fostering a harmonious relationship with these fascinating creatures and maintaining a balanced ecosystem. While wasps may have a reputation for being aggressive and stinging, it is important to note that not all types of wasps pose a threat to humans. By familiarizing ourselves with the different species, we can learn to coexist peacefully and appreciate the important role they play in our environment.
The Wasp Family
Wasps are a distinct species from bees, and it is crucial to understand their differences. Unlike bees, which are generally docile and focus on gathering nectar, wasps are carnivores that feed on other small creatures, particularly insects. This carnivorous nature sets them apart and is a key reason why some species can be more aggressive towards humans. Wasps have the ability to sting multiple times without harming themselves and can quickly alert other wasps by releasing alarm pheromones. Therefore, it is important to approach them with caution and respect their behavior.
Yellow Jackets
Yellow jackets are a common type of wasp in North America and are often mistaken for bees. They can be identified by their black and yellow striped markings, although their bodies are smooth rather than fuzzy like bees. Yellow jackets are known for their aggressive behavior, especially when their colonies are threatened. They typically nest in the ground or stone walls and can become very protective of their colony, attacking anyone who gets too close. Professional help is recommended when dealing with yellow jacket infestations to ensure the safety of both humans and pets.
European Hornets
European hornets, although not native to North America, can now be found in many parts of the United States. These hornets have a similar appearance to yellow jackets with striped black and yellow bodies. However, they typically nest in cavities at least six feet off the ground, such as the hollow of a tree, and they are active foragers both during the day and at night. Like yellow jackets, European hornets can become aggressive if their nests are disturbed, and professional help should be sought if a nest is found near the home.
Baldfaced Hornets
Baldfaced hornets, despite their name, are actually wasps rather than true hornets. They are known for their distinctive black and white facial markings and the football-shaped nests they build high in trees. While the size of their nests can be alarming, baldfaced hornets are typically not aggressive unless their nest is threatened. If a nest is located in a high-traffic area, it is advisable to seek professional help. Otherwise, these wasps are best left undisturbed.
Paper Wasps
Paper wasps are recognizable by their small, paper-like nests that hang from a single stalk. They come in a range of colors, including orange, red-brown, burgundy, and black and yellow stripes. Unlike some other species, paper wasps are generally less aggressive, and their colonies are smaller. They usually do not sting unless provoked. Paper wasps can actually be beneficial in pest control as they prey on caterpillars and other pests that can harm crops. It is recommended to leave paper wasp nests undisturbed unless they pose a direct threat.
Solitary Wasps
Solitary wasps are a diverse group of wasps that hunt alone rather than living in colonies. They belong to different families and play an important role in controlling insect populations. Unlike social wasps, solitary wasps are generally non-aggressive towards humans and are more focused on hunting their prey. By understanding and appreciating these solitary hunters, we can better appreciate their contribution to our ecosystem.
Understanding the common types of wasps found in North America allows us to coexist with these fascinating creatures. By employing caution and seeking professional help when necessary, we can ensure our safety while appreciating the important role these wasps play in our environment.
