A Homeowner’s Guide to 7 Common Wasps and Bees in Illinois
Image
Have you recently stepped outside and noticed buzzing insects near your home? Illinois is home to a variety of wasps and bees, many of which play a crucial role in pollination and pest control. However, some can be aggressive or pose a risk to homeowners. Knowing how to identify these stinging insects can help you determine whether they are a danger or a beneficial part of your yard’s ecosystem.
Common Bees in Illinois
Honey Bees
Image
- Appearance: Honey bees are about ½ inch long, with golden-brown, fuzzy bodies and black bands on their abdomen. Their legs are covered in tiny hairs that help collect pollen.
- Nest & Location: These social bees live in large colonies, often in managed hives or inside tree cavities and wall voids.
- Sting & Behavior: Generally non-aggressive, honey bees will sting only in defense. Their stingers are barbed, meaning they die after stinging.
- Pollination Role: Excellent pollinators, honey bees are crucial to Illinois agriculture and backyard gardens.
Bumble Bees
Image
- Appearance: Bumble bees are larger than honey bees (about ¾ inch), with black and yellow, fuzzy bodies. Some species may have orange markings.
- Nest & Location: These bees nest in underground burrows, compost piles, or abandoned rodent nests.
- Sting & Behavior: They are docile unless provoked. Unlike honey bees, they have smooth stingers and can sting multiple times.
- Pollination Role: Essential pollinators for wildflowers and crops like tomatoes and peppers.
Carpenter Bees
Image
- Appearance: Large (up to 1 inch), resembling bumble bees but with shiny, black abdomens and little hair.
- Nest & Location: Unlike social bees, carpenter bees are solitary and drill holes into untreated wood (eaves, decks, and siding) to lay eggs.
- Sting & Behavior: Males are territorial but do not sting. Females can sting but rarely do unless handled.
- Pollination Role: Moderate pollinators, especially for native plants.
Common Wasps in Illinois
Paper Wasps

- Appearance: Long, slender bodies (¾ to 1 inch) with brown or reddish coloring and yellow markings. They have smooth bodies and long legs.
- Nest & Location: Open, umbrella-shaped nests made from paper-like material, often under eaves, decks, or porch ceilings.
- Sting & Behavior: Mildly aggressive; they sting if their nest is disturbed. Unlike bees, they can sting multiple times.
- Pollination Role: Somewhat helpful pollinators and natural pest controllers, feeding on caterpillars and other insects.
Yellowjackets
Image
- Appearance: Small (½ inch), compact, and bright yellow with black stripes. They have smooth, shiny bodies.
- Nest & Location: Nests are often underground or inside wall voids. They build paper-like, enclosed structures.
- Sting & Behavior: Highly aggressive, especially in late summer. They can sting multiple times and will defend their nests fiercely.
- Pollination Role: Limited pollination but beneficial for pest control as they prey on other insects.
Bald-Faced Hornets (Dolichovespula maculata)
Image
- Appearance: Large (¾ inch to 1 inch), with black bodies and distinct white markings on the face.
- Nest & Location: Large, enclosed paper nests, typically high up in trees or on buildings.
- Sting & Behavior: Very aggressive if threatened. Their sting is painful, and they can sting multiple times.
- Pollination Role: Minimal, but they help control pests like flies and caterpillars.
Mud Daubers
Image
- Appearance: Slender, long-bodied (up to 1 inch), with metallic blue or black coloring and a narrow waist.
- Nest & Location: Solitary wasps that create mud tube nests on walls, under eaves, and in sheds.
- Sting & Behavior: Not aggressive; they rarely sting humans.
- Pollination Role: Limited, but they help control spider populations.
How to Handle Wasps and Bees Around Your Home
- Encourage Pollinators: If honey bees or bumble bees are nesting nearby, consider leaving them alone or contacting a beekeeper for safe relocation.
- Prevent Nesting: Seal gaps in wood structures to deter carpenter bees. Fill ground holes to prevent yellowjackets from nesting.
- Safe Removal: For wasp nests near high-traffic areas, consider hiring a professional stinging insect control service to remove them safely.
- Stay Safe: If you accidentally disturb a nest, move away calmly without swatting. Wasps and hornets are triggered by fast movement.
By learning to identify these common stinging insects in Illinois, homeowners can better understand their role in nature and take steps to manage them safely. Whether they’re helpful pollinators or aggressive pests, knowing what’s buzzing around your yard can help keep your home and family safe.
