Wasps, hornets, and yellowjackets – these buzzing, stinging insects are a common sight during warmer months, often causing fear and anxiety with their presence. While they all belong to the same order of insects (Hymenoptera), there are distinct differences in their appearance, behavior, and the threats they pose. Understanding these distinctions can help you identify the specific type of stinging insect you're dealing with and take appropriate precautions.
Physical Characteristics
Wasps:
This is a broad category encompassing various species, including paper wasps, mud daubers, and potter wasps. Generally, wasps have slender bodies with a narrow waist, long legs, and smooth, shiny skin. Their colors vary depending on the species, but they are often black, brown, or reddish with yellow markings.
Hornets:
Hornets are a subset of wasps, belonging to the genus Vespa. They are typically larger than other wasps, with a more robust body and a wider head. Their coloration is usually black and white or black and yellow. The European hornet, a common species in North America, has a brown and yellow striped abdomen.
Yellowjackets:
These wasps belong to the genera Vespula and Dolichovespula. They are smaller than hornets, with a shorter, stockier body. Yellowjackets are typically black and yellow, with distinct bands on their abdomen.
Nesting Habits
Wasps:
Wasps build diverse nests depending on the species. Paper wasps construct open, umbrella-shaped nests from chewed wood fibers, often found under eaves, in attics, or on tree branches. Mud daubers create mud nests that resemble organ pipes, while potter wasps build small, pot-shaped nests.
Hornets:
Hornets typically build large, enclosed nests made of paper-like material. These nests are often found in trees, shrubs, or under eaves. The bald-faced hornet, despite its name, is actually a type of yellowjacket and builds large, aerial nests.
Yellowjackets:
Yellowjackets construct enclosed nests, either underground or in cavities like wall voids or attics. Their nests are made of a papery material and can be quite large, housing thousands of individuals.
Behavior and Aggression
Wasps:
Most wasps are not inherently aggressive and will only sting if they feel threatened or their nest is disturbed. However, some species, like yellowjackets, can be more defensive and may sting with less provocation.
Hornets:
Hornets are generally more aggressive than other wasps and can deliver painful stings. They are known to defend their nests vigorously and may attack in groups if disturbed.
Yellowjackets:
Yellowjackets are highly aggressive and readily sting, especially when their nest is threatened. They are attracted to sweet foods and beverages, making them a common nuisance at picnics and outdoor gatherings.
Threats and Concerns
- Stings: All three types of insects can deliver painful stings that cause localized swelling, redness, and itching. For individuals allergic to insect venom, stings can trigger severe reactions, including anaphylaxis, which requires immediate medical attention.
- Nest Defense: Hornets and yellowjackets are particularly defensive of their nests and may attack in large numbers if disturbed. This poses a significant risk for individuals who unknowingly approach or disturb a nest.
- Property Damage: Carpenter bees, a type of wasp, can cause structural damage by excavating tunnels in wood to create their nests.
Prevention and Control
- Avoid Attracting Them: Keep food and beverages covered when outdoors, especially sweet items. Avoid wearing bright colors or floral patterns that may attract wasps.
- Maintain a Clean Yard: Remove fallen fruit, keep garbage cans sealed, and eliminate standing water to reduce attractants.
- Seal Entry Points: Caulk cracks and crevices in your home's exterior to prevent wasps from entering.
- Professional Pest Control: If you have a wasp, hornet, or yellowjacket nest on your property, it's best to contact a professional pest control service for safe removal.
