Wasps are common insects that can be found in residential areas, often making nests near homes, gardens, or even underground. While some wasps are beneficial to the ecosystem by controlling pest populations, their presence can also be a nuisance or even dangerous, especially if they become aggressive. In this article, we will explore the most common types of wasps you might encounter in residential areas and answer specific questions about their appearance and behavior.
Yellowjackets commonly build their nests in underground cavities, wall voids, or other enclosed spaces. They are attracted to sugary substances, garbage, compost piles, and flowers, making them a frequent sight in both urban and natural environments.Yellowjackets are known for their highly aggressive nature, especially when their nests are disturbed. Unlike bees, they have the ability to sting multiple times, and their stings often result in intense pain, swelling, or allergic reactions. This aggressiveness peaks in late summer and fall when their food sources become scarce.
Paper wasps build papery, umbrella-shaped nests from chewed wood fibers. These nests are often found under eaves, in attics, or on tree branches and shrubs. Their open structure with visible hexagonal cells makes them easy to identify.Paper wasps are comparatively less aggressive than yellowjackets but will sting if they feel their habitat is threatened. They are most active in late summer when colonies reach their peak size. Their role in controlling garden pests makes them beneficial, but their proximity to human activity can pose challenges.Visit our Species, Control, and DIY Guide sections for additional resources on wasps and ways to tackle a wasp infestation.
Hornets build large, papery nests made from chewed wood pulp. These nests are often found in trees, shrubs, or elevated locations such as attics and eaves. The enclosed structure of their nests distinguishes them from the open hexagonal nests of paper wasps.Hornets are very aggressive and sting multiple times if they perceive a threat. Their stings are particularly painful and can cause severe allergic reactions in sensitive individuals. Hornets are active foragers and often scavenge for sugary substances or prey on other insects.
Mud daubers build distinctive cylindrical nests out of mud. These nests are commonly found in sheltered locations such as sheds, garages, barns, or under eaves. The smooth, tube-like structures are easily recognizable.Mud daubers are non-aggressive and sting only if directly threatened. They are beneficial to ecosystems as they prey on spiders and other small pests, paralyzing them to store as food for their larvae. Their solitary nature and helpful habits make them a low-risk presence around homes.If you often spot these wasps in and around your property, it might be a sign of an on-going infestation. Get help from pest control professionals if the situation seems to have gone out of hands. Our team can provide a customized approach to protect your home effectively.
Carpenter bees bore into untreated or weathered wood to create nests. Their preferred sites include wooden decks, fences, eaves, and siding, where they drill circular holes to lay eggs and rear their young.Carpenter bees are non-aggressive and rarely sting unless directly handled or threatened. However, their burrowing can weaken wooden structures over time, especially if multiple generations reuse the same nesting sites. Male carpenter bees may appear intimidating as they hover near nests but are harmless and lack stingers.
Yellowjackets
Yellowjackets are small, highly aggressive wasps commonly mistaken for bees due to their appearance i.e. black and yellow markings. However, their smooth, shiny bodies and behavior distinguish them from other insects. These wasps are notorious for their territorial nature and their ability to sting multiple times, making them a significant concern during late summer and fall.Physical Characteristics of Yellowjackets
-
Size: Typically 0.5 to 0.75 inches in length. -
Color: Bright yellow with black markings on their bodies.
-
Body: Smooth and shiny, lacking the fuzz found on bees.
-
Wings: Clear and folded lengthwise when at rest.
-
Antennae: Long, thin, and black.

Paper wasps are slender, long-bodied wasps that are less aggressive than yellowjackets but still pose a risk if their nests are disturbed. Known for their papery nests, they are a common sight in sheltered outdoor areas during the warmer months.Physical Characteristics of Paper Wasps
-
Size: Typically 0.75 to 1 inch in length.
-
Color: Brown, yellowish, or reddish with lighter markings.
-
Body: Slender and elongated with a narrow “waist” connecting the thorax and abdomen.
-
Wings: Long and folded against their bodies when at rest.
-
Antennae: Medium-length and slightly curved.

Hornets are large, robust wasps known for their intimidating size and highly aggressive nature. They play a huge role in keeping pest populations under control but can pose risks to humans due to their painful stings and defensive behavior near nests.Physical Characteristics of Hornets
-
Size: Up to 2 inches long, significantly larger than other wasps.
-
Color: Typically black-and-white or yellow-and-black patterns on smooth, shiny bodies.
-
Body: Stocky and powerful with a distinctive broad head.
-
Wings: Strong, transparent wings used for swift and agile flight.
-
Antennae: Medium-length, straight, or slightly curved.

Mud daubers are solitary wasps known for their unique appearance and non-aggressive nature. Unlike social wasps, they rarely sting and are considered beneficial due to their pest-control habits.Physical Characteristics of Mud Daubers
-
Size: Smaller than yellowjackets, typically around 0.5 to 1 inch long.
-
Color: Black or metallic blue, with some species featuring yellow markings.
-
Body Shape: Long, slender bodies with extremely narrow waists connecting the thorax and abdomen.
-
Wings: Transparent or dark-tinted wings used for agile flight.

Carpenter bees are large, solitary bees often confused with bumblebees due to their size and appearance. While generally harmless, their nesting habits can lead to structural damage over time.Physical Characteristics of Large Carpenter Bees
-
Size: Large, ranging from 0.75 to 1 inch in length.
-
Color: Black or metallic blue with shiny, hairless abdomens.
-
Body Shape: Resemble bumblebees but lack the dense, fuzzy hair on their abdomens.
-
Wings: Transparent with a slight sheen, enabling quick and direct flight.
