What Are Bald-Faced Hornets — and Why Are They So Dangerous?

Despite being called hornets, bald-faced hornets (Dolichovespula maculata) are actually wasps — closely related to yellow jackets. They are named for the distinctive white and ivory markings covering their face and abdomen. At 3/4 of an inch, bald-faced hornet workers are noticeably larger than yellow jackets, and their colonies are among the most aggressively defensive stinging insects found in Southeast Michigan.

We remove aerial nests from trees, shrubs, eaves, and structures — and structural nests inside attics and wall voids — completely, in one visit, with full protective equipment.

How to Identify a Bald-Faced Hornet Nest

The bald-faced hornet nest is one of the most distinctive structures built by any stinging insect in Michigan. If you see a gray, football-to-basketball-sized papery mass attached to a tree branch, eave, shrub, or structure — and it grows larger week by week — you have a bald-faced hornet nest. Do not approach or disturb it.

Bald-Faced Hornet Removal — Frequently Asked Questions

Are bald-faced hornets actually hornets?

No. Despite the name, bald-faced hornets (Dolichovespula maculata) are actually wasps — closely related to yellow jackets. They are significantly larger than yellow jackets and more aggressive in nest defense. True hornets in North America include only the European hornet (Vespa crabro).

Are bald-faced hornets more dangerous than yellow jackets?

In some respects, yes. While yellow jacket colonies are far larger (up to 15,000 workers vs. 400–700 for bald-faced hornets), bald-faced hornets are more aggressive in defense and pursue threats over a larger radius — up to 60 feet from the nest. Their venom is also notably more potent. Both require professional removal — do not approach an active bald-faced hornet nest for any reason.

When is bald-faced hornet season in Michigan?

Queens emerge in April and May and begin building colonies immediately. Colony size grows through June and July, with nests reaching dangerous size by late July and August. The most dangerous period is August through September when colonies are at peak population and workers are most aggressive. Workers die off in October and November. Only mated queens survive Michigan winters, establishing new nests the following spring.

Can I remove a bald-faced hornet nest myself?

No — not safely, particularly in July through September when colonies are at full size. Bald-faced hornets respond to any disturbance with an immediate mass stinging response and will chase perceived threats up to 60 feet. Store-bought spray reaches only the nest exterior — hundreds of workers inside are unharmed and emerge agitated. For any nest larger than a baseball, professional removal with full protective equipment is the only safe approach.

How much does bald-faced hornet removal cost in Michigan?

Hi-Tech removal costs $150–$300 for small accessible aerial nests; $250–$450 for large late-season nests; $350–$550 for elevated or difficult-access locations; and $300–$500 for structural nests inside attics or wall voids. All pricing includes a free inspection and transparent quote before any work begins. Call 248-569-8001 for same-day availability.

Should I wait until winter to remove the nest when the hornets are gone?

While it is physically safe to approach an abandoned nest in December or January, waiting until winter is not the best strategy. Mated queens that overwintered near the nest often return to establish new colonies in the same spot the following spring. Removing the nest in fall and sealing any structural gaps is the most effective way to break that cycle. Dead nest material inside walls also attracts secondary pests including rodents through winter.

How do bald-faced hornets get inside attics and wall voids?

Bald-faced hornets enter structures through any unscreened or unsealed opening — soffit vent openings, fascia board gaps, spaces where siding meets rooflines, and utility penetrations. Southeast Michigan's older housing stock has more of these gaps than modern construction. If you see bald-faced hornets consistently flying in and out of a specific point on your home's exterior, the nest is already established inside. Call Hi-Tech immediately — do not seal the opening without treating the colony first.

How quickly can Hi-Tech respond to a bald-faced hornet emergency?

Hi-Tech provides same-day emergency response throughout Southeast Michigan — Wayne, Oakland, and Macomb Counties. We answer calls 7 days a week from 8:30 AM to 10:00 PM. If someone has been stung multiple times and shows signs of an allergic reaction — throat tightening, widespread hives, dizziness, difficulty breathing — call 911 first, then call 248-569-8001.
