When most people in the Treasure Valley say “hornet,” they are usually referring to bald-faced hornets or yellowjackets. Both insects are highly aggressive, capable of delivering multiple painful stings, and will fiercely defend their nests. Because of the risks involved, safe and professional removal is essential.
Bald-Faced Hornets
Despite their name, bald-faced hornets are actually a type of wasp. They are black with white markings and build large, football-shaped paper nests, often found hanging in trees, shrubs, or attached to buildings. Colonies can grow to hundreds of hornets by late summer. They are particularly aggressive when their nest is disturbed.
Yellowjackets
Yellowjackets are smaller but just as dangerous. They typically nest in the ground, wall voids, or structures such as sheds and decks. In late summer and fall, they become especially problematic around trash cans, picnics, and outdoor gatherings because they’re attracted to sugary foods and drinks. Unlike bees, yellowjackets can sting repeatedly.
Seasonal Activity
Hornets and yellowjackets begin appearing in spring as queens emerge from overwintering. Colonies expand through summer and reach peak activity in August and September. By fall, both species become more aggressive as food sources dwindle. This is often when homeowners in Boise, Nampa, and Meridian notice the most problems.
Risks and Concerns
Painful Stings: Can cause allergic reactions or serious medical emergencies.
Aggressive Defenders: Both bald-faced hornets and yellowjackets will swarm if their nest is threatened.
Multiple Nest Sites: Hidden ground nests or aerial nests can make infestations hard to spot until it’s too late.
