Bald-faced hornets build the large, gray, football-shaped paper nests you often spot hanging from a tree, eave, or shrub around Bellingham and Whatcom County, and by late summer a single nest can hold hundreds of fiercely protective workers. They are highly defensive and will swarm to sting anyone who ventures too close, which makes an accessible nest a real hazard for families and pets. Sasquatch Pest Control removes bald-faced hornet nests safely, with a 100% service guarantee and no contracts.

How to Identify Bald-Faced Hornets

Despite the name, the bald-faced hornet is actually a large aerial yellowjacket, roughly 1/2 to 3/4 inch long, with a mostly black body marked by striking ivory-white patterning on the face and the tip of the abdomen. This white-and-black coloring sets it apart from the yellow-and-black yellowjackets it is related to. Their nests are the giveaway: a gray, papery, enclosed globe built from chewed wood fiber, often the size of a basketball, hanging from tree branches, tall shrubs, utility poles, or the eaves and soffits of homes, with a single entrance near the bottom.

Signs of a Bald-Faced Hornet Problem

The most obvious sign is the nest itself, a large gray paper sphere with hornets streaming in and out of a hole near its base. Before you spot it you may notice heavy hornet traffic patrolling a particular tree, hedge, or corner of the house. Unlike scavenging yellowjackets, bald-faced hornets are predators that hunt other insects, so they are less likely to swarm your picnic and more likely to be defending a nesting area. Hornets repeatedly bumping or dive-bombing you as you approach a spot in the yard is a warning that a nest is close by.

How Sasquatch Treats Bald-Faced Hornets in Whatcom County

Because bald-faced hornet colonies are large and aggressive, Sasquatch handles removal with full protective equipment and a careful plan. We inspect to confirm the nest location and identify the entrance, then treat the nest directly, usually in cooler morning or evening hours when more hornets are home, driving material into the colony to eliminate the workers and queen. Once activity has stopped we can physically remove the accessible nest so it cannot be reused or mistaken for active. We verify the colony is dead before finishing, and every service is backed by our 100% guarantee with no long-term contract.

How to Prevent Bald-Faced Hornets

Bald-faced hornets prefer to nest in trees, shrubs, and along rooflines, so keep an eye on these areas from spring onward when queens start small, easily managed nests. Trim dense shrubbery and overhanging branches near the house, seal gaps around eaves and soffits, and repair vent screens to discourage sheltered nesting spots. Because these hornets prey on other insects, reducing general pest activity around your property makes it slightly less attractive. The most important step is early detection: a nest the size of a golf ball in June is far safer and simpler to remove than a basketball-sized colony in September, so call at the first sighting.

Frequently Asked Questions

How much does bald-faced hornet treatment cost in Bellingham?

The price depends on the nest size, its height, and how accessible it is, since a nest tucked high in a tree or under a second-story eave takes more work than one on a low branch. Sasquatch provides a free upfront quote after evaluating the nest, and there is never a long-term contract. Treating an early-season nest is quicker and less costly than a mature fall colony, so calling early saves money.

Are bald-faced hornets dangerous?

Yes. They are among the most defensive stinging insects in the Pacific Northwest and will aggressively swarm anything they perceive as a threat to the nest, delivering repeated stings. For people allergic to insect venom this can be life-threatening. Any nest within reach of walkways, doors, decks, or play areas should be treated by a professional rather than approached.

Are bald-faced hornets the same as yellowjackets?

They are close relatives, both social wasps in the same family, but bald-faced hornets are larger, build enclosed aerial paper nests, and wear black-and-white rather than yellow-and-black coloring. Yellowjackets are usually smaller, often nest in the ground or in wall voids, and scavenge human food. The treatment approach differs, which is why correct identification matters.

What time of year are bald-faced hornets most active in Whatcom County?

Colonies start small in spring, build steadily through summer, and reach their largest and most defensive point in late August and September. Cooler fall weather eventually kills the workers, and the nest is not reused the following year. Late summer is when nests become most noticeable and encounters most common around Bellingham homes.

Should I knock down a bald-faced hornet nest myself?

No. Disturbing one of these nests without professional gear almost always provokes a mass defensive attack, and spraying from a distance rarely eliminates the colony while making the hornets far more aggressive. Nests high off the ground add a fall risk on top of the stings. A trained technician removes the nest safely and confirms the colony is dead.
