Bald-Faced Hornets in Connecticut: What Homeowners Need to Know

Also known as: Aerial Yellowjackets, White-Faced Hornets

Introduction

If you've spotted large, aggressive wasps with distinctive white markings around your Connecticut property, you're likely dealing with bald-faced hornets (Dolichovespula maculata). Despite their name, these aren't true hornets but rather a species of aerial yellow jacket that poses unique challenges for homeowners in Hartford, Tolland, and Litchfield Counties.

What Are Bald-Faced Hornets?

Bald-faced hornets are large, aggressive wasps easily identified by their black bodies and distinctive white facial markings. These aerial yellow jackets build paper-like nests high in trees, under eaves, or in other elevated locations, making them particularly challenging to manage safely.

Key Identification Features:

• Size: 12-15mm long (larger than typical yellow jackets)
• Color: Black body with white markings on face and abdomen
• Nest Location: Aerial nests, typically 3+ feet off the ground
• Activity Period: Most active from late spring through early fall

The Dangerous Defense Mechanism You Need to Know

Warning: Bald-faced hornets possess a unique and dangerous defense capability. Unlike other stinging insects, these aerial yellow jackets can spray ven om from their stingers at distances up to 10 feet. This venom spray can:

• Cause temporary blindness if it contacts your eyes
• Disorient and confuse potential threats
• Mark you with pheromones that attract other hornets to attack
• Lead to multiple stings as they can sting repeatedly without losing their stinger

Aggressive Pursuit Behavior

When threatened, bald-faced hornets will:

• Follow perceived threats for considerable distances
• Remember faces and return to attack the same person
• Rally nest mates for coordinated attacks
• Remain aggressive even after the initial threat has moved away

Seasonal Activity in Connecticut

Spring (April-May): Queens emerge and begin nest construction Summer (June-August): Peak activity, largest colony size Fall (September-October): Most aggressive period as food sources dwindle Winter: Colonies die off, only fertilized queens survive

Health Risks and Medical Concerns

Immediate Dangers:

• Multiple stings can cause severe allergic reactions
• Venom spray to eyes requires immediate medical attention
• Anaphylactic shock in sensitive individuals
• Secondary infections from untreated sting sites

When to Seek Emergency Care:

• Difficulty breathing or swallowing
• Swelling of face, lips, or throat
• Rapid pulse or dizziness
• Venom contact with eyes
• Multiple stings (10+ stings for adults, fewer for children)

Prevention Strategies for Connecticut Homeowners

Property Maintenance:

• Remove food sources: Secure garbage cans, clean up fallen fruit
• Eliminate water sources: Fix leaky faucets, remove standing water
• Trim vegetation: Keep trees and shrubs away from structures
• Seal entry points: Close gaps in soffits, eaves, and siding

Seasonal Precautions:

• Spring: Inspect for early nest development
• Summer: Avoid wearing bright colors or strong fragrances outdoors
• Fall: Exercise extreme caution as hornets become most aggressive

Why DIY Removal Is Dangerous

1. Venom spray capability makes traditional approaches ineffective
2. Aerial nest locations require specialized equipment
3. Aggressive pursuit behavior can lead to dangerous chase scenarios

Frequently Asked Questions

Q: How can I tell if it's a bald-faced hornet nest versus other wasps?A: Bald-faced hornet nests are gray, paper-like, and football-shaped, typically located 3+ feet off the ground. They're larger than typical wasp nests and have a single entrance at the bottom.
