Hornet Removal in Connecticut & New York
Safe, professional removal of aggressive hornet nests. Protect your family from painful stings. Licensed in both states.
Hornets are large, aggressive stinging insects common in Connecticut and New York. Unlike bees, hornets can sting multiple times and often attack in groups when defending their nests. Their nests grow throughout summer, peaking in late summer and fall when colonies are largest and most defensive. Professional removal is essential for safety—DIY attempts often result in painful stings and incomplete nest elimination.

Our Hornet Removal Process
Safe, professional nest elimination with protective equipment and proper techniques.
Assessment
Locate nest, identify species, and plan safe removal approach.
- Identify hornet species
- Locate all nests (some properties have multiple)
- Assess nest size and colony strength
- Plan safest treatment approach
Treatment
Apply professional products to eliminate colony.
- Wear full protective equipment
- Direct nest treatment when accessible
- Dust application for wall/cavity nests
- Quick-acting products for safety
Nest Removal
Remove nest after colony is eliminated (when safe).
- Wait 24-48 hours for complete elimination
- Remove accessible aerial nests
- Seal entry points to prevent re-use
- Dispose of nest properly
⚠️ Never Attempt DIY Hornet Removal
Hornet nests contain hundreds of aggressive defenders that attack in swarms when threatened. DIY attempts—spraying from ladders, knocking down nests, or using store-bought products—often result in multiple painful stings and incomplete elimination. Hornets are most aggressive in late summer and fall when colonies are largest. We use professional-grade protective equipment and products designed for rapid knockdown. Your safety is our priority.
Hornet Removal Questions
Hornet stings are painful and potentially dangerous:
- Multiple stings: Unlike bees, hornets can sting repeatedly
- Group attacks: Defend nests as a swarm—dozens can attack at once
- Painful venom: Causes immediate pain, swelling, and redness
- Allergic reactions: Can cause severe reactions in sensitive individuals
- Anaphylaxis risk: Life-threatening for those with venom allergies
- Medical attention: Seek emergency care for multiple stings or allergic symptoms
Hornet aggression increases through the season:
- Spring (April-May): Queens building new nests; relatively docile
- Summer (June-August): Colonies growing; moderately defensive
- Late summer/Fall (September-October): Peak aggression—colonies are largest
- Near nests: Extremely defensive within 10-15 feet of nest
- Vibrations: Mowing, trimming near nests triggers attacks
Fall removal is most dangerous but often most necessary.
Nest locations vary by species:
- Bald-faced hornets: Aerial nests in trees, shrubs, eaves, porches
- European hornets: Tree cavities, wall voids, attics, hollow spaces
- High locations: Often 10-60 feet off ground in trees
- Protected spots: Under eaves, in dense shrubs, inside structures
- One nest per queen: Each colony builds one primary nest per season
Hornet colonies are annual—they don't reuse nests:
- Winter: All workers and males die; only fertilized queens survive
- Spring: Queens emerge and build new nests (not in old ones)
- New locations: Queens may build near previous nests but not inside them
- Old nests: Safe to remove after first hard frost
- Prevention: Remove nests in fall/winter to discourage new queens
Cost varies based on several factors:
- Nest location: Ground-level vs high in tree vs inside wall
- Nest size: Early season (small) vs late season (large)
- Accessibility: Easy access vs ladder work vs wall removal
- Number of nests: Single nest vs multiple nests
- Species: Aerial nests vs cavity nests requiring different approaches

Hornet Prevention Tips
🔍 Spring Inspections
Check eaves, porches, and trees in April-May for new nests—easier to remove when small.
🗑️ Remove Food Sources
Keep garbage sealed; don't leave food or sugary drinks outdoors—attracts hornets.
🪹 Remove Old Nests
Remove old nests in winter after frost—prevents queens from building nearby.
🔒 Seal Entry Points
Fill tree cavities and seal holes in siding/soffits to prevent cavity-nesting hornets.
🌳 Trim Vegetation
Keep shrubs and trees trimmed away from house—makes inspection easier.
📞 Early Removal
Call immediately if you find a nest—small nests are safer and cheaper to remove.
