Wasp, Bee, and Hornet Identification Guide (Idaho)

Quick answer: Bees are fuzzy and beneficial. Wasps and hornets are smooth, slim-waisted, and can sting repeatedly. In Idaho, the six stinging insects you'll see around your home are honeybees, bumblebees, yellow jackets, paper wasps, bald-faced hornets, and mud daubers. Yellow jackets are the most dangerous, mud daubers are the least, and the rest fall in between.

Our Green Guard Pest Control technicians clear hundreds of nests every season across Boise, Meridian, Eagle, Nampa, and Kuna. By mid-May 2026 we're already getting two or three wasp calls a day, mostly from south and west-facing eaves where the afternoon sun warms paper wasps into early activity. This guide walks through the species we actually see in the Treasure Valley, so you can ID what's on your house and decide what to do about it.

Before diving into specific species, understand the fundamental differences between bees and wasps. For a focused side-by-side comparison, see our bee vs wasp identification guide for the Treasure Valley.

Bees

Wasps and Hornets

Honeybee populations are declining worldwide. If you find honeybees on your property, contact a local beekeeping association for free relocation services rather than calling an exterminator.

Honeybees (Apis mellifera) are crucial pollinators that should be protected whenever possible. If you find a honeybee swarm or hive, contact a local beekeeper for relocation rather than extermination.

Identification

Bumblebees are large, fuzzy bees that are excellent pollinators. They're generally docile and rarely sting unless directly handled or their nest is disturbed. In the Treasure Valley we see them most often around home gardens in Garden City, the Boise Bench, and Meridian's Linder corridor from May through August, usually nesting in abandoned vole tunnels or under decks.

Identification

Yellow jacket nests can contain thousands of workers by late summer. They become increasingly aggressive in August and September. NEVER attempt to remove a yellow jacket nest yourself - their attacks are coordinated and can result in dozens of stings.

Yellow jackets (Vespula species) are the most dangerous stinging insect in Idaho. They're aggressive, especially in late summer, and they nest in hidden spots like old rodent burrows or wall voids. In the Treasure Valley, we get the heaviest yellow jacket call volume from August through mid-September, when colonies are at peak size (often 2,000 to 4,000 workers) and food sources outside start drying up. Boise's North End and Eagle foothills are hotspots because mature landscaping gives queens lots of hidden cavity options. For a deeper look at telling Vespula species apart, see our yellow jacket identification guide.

Identification

Yellow jackets nest in concealed locations, making accidental encounters common:

Paper wasp nests are often the only nests homeowners can safely remove themselves - IF the nest is small (under 2 inches), easily accessible, and you have no allergies. However, professional removal is always the safest option.

Paper wasps (Polistes species) are the most common stinging insect call we get in the Treasure Valley. They build distinctive open-celled, umbrella-shaped nests and are less aggressive than yellow jackets, but they'll still defend their nests. Around Boise and Meridian we find these tucked under second-story eaves, soffits, patio covers, and behind shutters from April through October.

Identification

Bald-faced hornets will attack anyone who comes within 10-15 feet of their nest. They can sting repeatedly and will pursue threats for a significant distance. NEVER attempt removal yourself - always call professionals.

Bald-faced hornets (Dolichovespula maculata) are actually a type of yellow jacket despite the name. They build large, enclosed paper nests and are extremely aggressive when defending their colony. Most of the bald-faced hornet nests we remove around Boise show up between July and early October, usually 10 to 20 feet up in a tree or on the gable end of a two-story house. The football-shaped gray paper nest is unmistakable. For a complete guide to identifying and safely handling these aggressive insects, see our detailed bald-faced hornet guide for Idaho homeowners.

Identification

Mud daubers are beneficial insects that prey on spiders, including black widows. Consider tolerating their presence unless nests are in high-traffic areas. Their old nests can be scraped off after the wasps have left.

Mud daubers are solitary wasps that build distinctive mud tube nests. Unlike social wasps, they don't defend their nests aggressively and rarely sting. They're actually beneficial because they prey on spiders, including black widows.

Identification

Professional wasp and hornet removal is fast, safe, and affordable. Our technicians identify the species, locate every nest entrance, and knock the colony down with our free re-service guarantee behind the work.

Call a professional if the nest is larger than a golf ball, hidden inside a wall or underground, or belongs to yellow jackets or bald-faced hornets. The same goes if anyone in your household has a sting allergy, or if the nest is near a door, patio, or play area. These situations carry real safety risks that make DIY removal a bad idea.
