Missouri’s summer months bring more than sunshine and backyard barbecues. They also signal the return of buzzing stinging insects, some beneficial and others a potential danger to your home and family. Correctly identifying these insects is the first step in preventing stings and knowing when to call for help.
This guide of common pest types helps you identify the most common stinging insects in Missouri, with practical tips to distinguish yellowjackets from paper wasps, bumblebees from carpenter bees, and more.
Why Identifying Missouri’s Stinging Insects Matters
Not every flying insect is just a nuisance. Some play important roles in pollination, while others can damage property or become aggressive in the summer. Knowing who’s who will help you:
- Prevent potentially dangerous encounters, especially for those with allergies
- Avoid unnecessary panic or harmful removal of vital pollinators
- Take the right steps for safe nest removal
Fast Guide Missouri’s Most Common Stinging Insects
Yellowjackets
- Appearance: Black and yellow patterned abdomen. Small size, 3/8 to 5/8 inch long. Queens are about 25 percent larger.
- Behavior: Social, forming colonies of thousands; very defensive, especially near nests found on buildings or in vegetation.
- Danger Level: High for sensitive individuals. Their sting delivers a strong toxin that can cause severe reactions.
- Where You’ll Find Them: On homes, in the ground, among shrubs. Aggressiveness peaks during fall when they’re hunting for sugary foods.
Quick tip
Yellowjackets fly fast, often hover aggressively when disturbed, and can sting multiple times.
Paper Wasps
- Appearance: Brown and black with orange or pale brown oval patches on the belly. Long, slender bodies.
- Behavior: Not usually aggressive unless provoked, but will sting if you disturb their nest.
- Nesting Habits: Small, open “paper” nests hanging on porch ceilings, under decks, or in other sheltered areas.
- Risk: Nuisance more than a real danger, but a sting can be painful.
Quick tip
Paper wasps will guard their nests, but tend to mind their own business unless directly threatened.
Honey Bees
Honey bees are one of the most recognized and loved stinging insects, largely due to their critical role in pollination.
- Appearance: Fuzzy, golden-brown with black bands. Moderate in size.
- Behavior: Highly social, with colonies that persist for years.
- Where You’ll Find Them: Often in tree hollows, sometimes in attics or chimneys.
- Safety Note: Removal of a hive should always be left to professionals. Honey bees are a protected species due to their environmental importance.
Quick tip
Honey bees usually won’t sting unless directly threatened. Their sting is single-use and fatal to the bee.
Baldfaced Hornet
- Appearance: Black bodies, striking white face; larger than most common wasps.
- Nests: Strong, round, gray papery nests, often suspended high (up to 66 feet!), ranging from softball to basketball in size.
- Behavior: Top predators of other insects; very protective of their nest.
- Risk: Their aggression and ability to sting repeatedly make them hazardous when too close to their nest.
Quick tip
Avoid nest disturbance and keep distance; their nests are usually obvious and large.
Bumble Bees
Known for their “teddy bear” appearance, bumble bees are actually vital to plant and crop pollination.
- Appearance: Big, robust, and fuzzy with black and yellow stripes.
- Behavior: Generally docile unless their underground nest is threatened.
- Stings: Capable of stinging more than once, but usually reserved as a last resort.
- Nesting Spots: Under sheds, around patios, inside attic soffits.
Quick tip
Leave these beneficial insects alone if possible; most stings occur when someone accidentally steps near a nest.
Carpenter Bees
Carpenter bees are sometimes mistaken for bumble bees but have important differences.
- Appearance: Similar in size, but often have shiny, hairless (black) abdomens with few yellow stripes.
- Behaviors: Solitary. Drill round holes into bare or weathered wood to lay eggs.
- Risks: Rarely sting, but repeated activity can weaken decks, rails, and eaves.
- Where to Spot Damage: Look for perfectly round holes in wood, sometimes with sawdust beneath.
Quick tip
Painted or sealed wood is less inviting to carpenter bees. Repair exposed wood promptly.
Mud Daubers
- Appearance: Slender with a dark, often metallic abdomen; resembles some wasps.
- Nesting Habits: Solitary; build small, tube-like nests from mud, often found under eaves or in sheds.
- Aggression: Very low, rarely sting people.
- Risk: Mainly a visual nuisance, not a safety concern.
Quick tip
If you see thin, muddy tubes on your walls, you’re dealing with mud daubers. Scrape nests away if needed, as the insect is unlikely to sting in retaliation.
What to Do if You Find a Nest
- Do not try to remove large nests yourself, especially those belonging to yellowjackets, hornets, or honey bees.
- Leave beneficial pollinators like honey bees and bumble bees alone when possible.
- For high-traffic areas or if individuals are allergic, keep a safe distance and contact a pest control expert.
- Secure outdoor food sources, especially in late summer when wasps get more aggressive looking for sweets.
