Paper Wasps vs. Yellow Jackets: A Comprehensive Guide to Identification, Behavior, and Control

Introduction

Paper wasps and yellow jackets are common stinging insects that can be found in North America and other parts of the world. While they share some similarities, there are also several key differences that set these two insects apart.

Identification

Appearance:

• Paper wasps: Elongated, slender bodies with black or brown markings and long, slender wings. They have a distinctive "paper" nest that is typically constructed out of wood pulp.
• Yellow jackets: Stout, rounded bodies with yellow and black markings and short, stubby wings. They build their nests in cavities, such as underground burrows or in walls.

Nests:

• Paper wasps: Build open, exposed nests that are typically gray or brown in color. The nests are made of papery material that is chewed and mixed with saliva.
• Yellow jackets: Build enclosed nests that are typically hidden in cavities. The nests are made of a papery material that is similar to that used by paper wasps, but it is often darker in color.

Behavior

Aggression:

• Paper wasps: Generally less aggressive than yellow jackets and are more likely to sting if they are threatened or provoked.
• Yellow jackets: Highly aggressive and are known to sting without provocation. They can also be more persistent than paper wasps when they attack.

Diet:

• Paper wasps: Feed primarily on insects, such as flies, mosquitoes, and caterpillars. They also feed on nectar and other sugary liquids.
• Yellow jackets: Feed on a wide variety of insects, including flies, mosquitoes, and grasshoppers. They also feed on sweet substances, such as fruits, sugary drinks, and honey.

Nesting:

• Paper wasps: Build their nests in sheltered areas, such as under eaves, on trees, or in bushes. They generally build only one nest per season.
• Yellow jackets: Build their nests in cavities, such as underground burrows or in walls. They often build multiple nests per season.

Stings

Venom:

• Paper wasps: The venom of paper wasps is generally less potent than that of yellow jackets.
• Yellow jackets: The venom of yellow jackets is highly toxic and can cause severe pain, swelling, and allergic reactions in some individuals.

Symptoms:

• Paper wasps: Stings from paper wasps typically cause pain, redness, and swelling. In most cases, the symptoms will go away within a few hours.
• Yellow jackets: Stings from yellow jackets can cause severe pain, swelling, and allergic reactions. In some cases, a yellow jacket sting can be life-threatening.

Treatment:

• Paper wasps: Treat the sting by applying a cold compress and taking over-the-counter pain medication.
• Yellow jackets: Seek medical attention immediately if you are stung by a yellow jacket.

Habitat

Range:

• Paper wasps: Found throughout North America, including Canada, the United States, and Mexico.
• Yellow jackets: Also found throughout North America, but they are more common in the eastern United States.

Preferred Habitat:

• Paper wasps: Prefers to nest in sheltered areas, such as under eaves, on trees, or in bushes. They are often found in residential areas, as well as in natural habitats.
• Yellow jackets: Prefers to nest in cavities, such as underground burrows or in walls. They are often found in residential areas, as well as in parks, forests, and other natural habitats.

Population Trends and Control

Population:

• Paper wasps: Populations of paper wasps have been declining in recent decades due to habitat loss and the use of pesticides.
• Yellow jackets: Populations of yellow jackets have been increasing in recent decades due to the availability of nesting sites and food sources.

Control:

• Paper wasps: Can be controlled by eliminating nesting sites, removing food sources, and using traps.
• Yellow jackets: Can be controlled by the same methods used for paper wasps, but they are more difficult to control due to their aggressive behavior.

Common Mistakes to Avoid

• Mistaking paper wasps for yellow jackets: Paper wasps are often mistaken for yellow jackets because of their similar appearance. However, there are several key differences that can help you tell them apart.
• Trying to swat away wasps or yellow jackets: This will only make them more likely to sting.
• Running away from wasps or yellow jackets: This will only make them chase you.
• Using pesticides to kill wasps or yellow jackets: This is not an effective way to control these insects, and it can be harmful to other wildlife.

• Identify the insect: If possible, try to identify the insect that is bothering you. This will help you determine the best way to deal with it.
• Remove the threat: If the insect is on you, try to remove it gently. Do not swat at it or squeeze it.
