Hornet nests are impressive architectural structures that can house hundreds of aggressive stinging insects across Washington, Idaho, Oregon, and Arizona. Accurate identification of nest type, size, and location helps determine the best removal approach and timing. Never attempt DIY removal of active hornet nests-professional treatment ensures safety.

Hornet Nest Characteristics

Bald-Faced Hornet Nests

  • Shape: Large, teardrop or football-shaped
  • Size: Basketball to beach ball (12-24 inches)
  • Material: Gray paper-like material (chewed wood fibers)
  • Entrance: Single opening at bottom
  • Location: Trees, shrubs, under eaves (10-60 feet high)
  • Population: 100-400 workers at peak

European Hornet Nests

  • Location: Tree cavities, wall voids, attics
  • Size: Varies (hidden in cavities)
  • Entrance: Small opening to cavity
  • Activity: Night flying (attracted to lights)

Comparison: Hornets vs Wasps vs Bees

Paper Wasp Nests

  • Shape: Open umbrella-shaped comb
  • Size: 3-10 inches diameter
  • Location: Under eaves, porch ceilings, railings
  • Visibility: Cells visible (no outer covering)

Yellow Jacket Nests

  • Location: Underground, wall voids, attics
  • Size: Can be massive (thousands of workers)
  • Entrance: Small hole (heavy traffic)
  • Visibility: Usually hidden

Honey Bee Hives

  • Material: Wax combs
  • Location: Tree cavities, wall voids, structures
  • Behavior: Less aggressive than hornets
  • Note: Protected species; require relocation, not extermination

Nest Development Timeline

  • Early spring: Queen emerges, starts small nest (golf ball size)
  • Late spring: First workers emerge, nest grows rapidly
  • Summer: Peak size and population (most dangerous period)
  • Fall: New queens produced; colony begins decline
  • Winter: Colony dies; only new queens survive

Safety Considerations

  • ❌ Never approach active nest closely
  • ❌ Don't throw objects at nest
  • ❌ Avoid vibrations (mowing, trimming near nest)

Frequently Asked Questions About Hornet Nest Identification

Question: What does a hornet nest look like?

Answer: Hornet nests are large, gray, paper-like structures with teardrop or football shapes. They're enclosed (unlike open wasp combs) with a single entrance hole at the bottom. Nests can reach basketball size or larger by late summer.

Question: Where do hornets build nests?

Answer: Hornets build nests in trees, shrubs, under eaves, in attics, and occasionally underground. Bald-faced hornets prefer aerial locations 3+ feet high. European hornets nest in cavities including wall voids and hollow trees.

Question: How can I tell if it's a hornet nest or wasp nest?

Answer: Hornet nests are fully enclosed with paper-like covering and single entrance. Wasp nests (paper wasps) are open, umbrella-shaped combs with visible cells. Yellow jacket nests are enclosed but usually in ground or wall voids.

Question: Are hornets aggressive?

Answer: Yes, hornets are aggressive when defending nests. They attack in groups, sting multiple times, and pursue threats. Bald-faced hornets are particularly defensive. Never approach nests-professional removal is strongly recommended.

Question: When are hornet nests most active?

Answer: Hornet nests are most active in late summer and early fall when populations peak. Nests start small in spring, grow through summer, and reach maximum size/activity in August-September. Activity decreases after first frost.

Question: Can I remove a hornet nest myself?

Answer: DIY hornet nest removal is extremely dangerous and not recommended. Hornets attack aggressively, causing multiple stings and potential allergic reactions. Professional removal ensures safety using protective equipment and appropriate products.

Question: How big do hornet nests get?

Answer: Hornet nests start golf-ball sized in spring and can reach basketball size or larger by fall. Large nests may house 400-700 hornets. Nest size indicates colony age and population-larger nests require professional treatment.

Question: Do hornets reuse nests?

Answer: No, hornets don't reuse nests. Colonies die in fall; only fertilized queens survive winter. Queens build new nests in spring. However, old nest locations may attract new queens. Remove old nests to discourage rebuilding.

Question: What should I do if I find a hornet nest?

Answer: If you find a hornet nest, keep family and pets away, avoid disturbing the area, don't attempt DIY removal, and call professional pest control immediately. Mark the location from a safe distance for technician reference.

Question: How much does professional hornet nest removal cost?

Answer: Professional hornet nest removal costs $150-$400 depending on nest size, location, and accessibility. Difficult locations (high trees, wall voids) cost more. Emergency service may include additional fees. Professional removal ensures safety and complete elimination across Washington, Idaho, Oregon, and Arizona.

Hornet Nest Identification FAQs

Common questions about identifying and removing hornet nests

QUESTION:How can I identify a hornet nest versus a wasp nest?

ANSWER:Hornet nests are large, teardrop-shaped, gray paper structures typically in trees or under eaves, with entrance at bottom. Bald-faced hornets build football-sized nests 10-60 feet high. Paper wasp nests are smaller, open-comb umbrellas under eaves. Yellow jacket nests are hidden in ground or wall voids. In Washington, Idaho, and Oregon, bald-faced hornets are common. Our identification guide shows differences. For professional hornet nest identification across Washington, Idaho, Oregon, and Arizona, contact Patriot Pest Control.

QUESTION:When is the best time to remove a hornet nest?

ANSWER:Remove hornet nests in early spring when colonies are small (queen only) or late fall after first frost kills the colony. Never attempt removal during summer when nests contain hundreds of aggressive workers. Treat at dusk or dawn when hornets are less active. Our wasp removal guide covers safe timing. For professional hornet nest removal in Washington, Idaho, Oregon, and Arizona, schedule service with Patriot Pest Control-we handle nests safely year-round.

QUESTION:Where do hornets typically build nests?

ANSWER:Bald-faced hornets build nests in trees, shrubs, under eaves, on building sides, and occasionally in attics. They prefer high locations (10-60 feet) with protection from weather. European hornets nest in hollow trees, wall voids, and attics. Nests are built from chewed wood fibers mixed with saliva. Our nest location guide covers common sites across Washington, Idaho, Oregon, and Arizona.

QUESTION:How big do hornet nests get?

ANSWER:Bald-faced hornet nests start small in spring (golf ball size) and grow to basketball or larger by late summer, housing 400-700 workers. Nests can reach 24 inches tall and 18 inches wide. European hornet colonies are smaller (200-400 workers). Nests are abandoned after first frost and not reused. Our hornet control addresses nests of all sizes.

QUESTION:Are hornets more aggressive than wasps?

ANSWER:Yes, hornets are generally more aggressive than paper wasps, especially when defending nests. Bald-faced hornets aggressively defend nests within 10-15 feet, pursuing threats. They can sting multiple times and spray venom. Yellow jackets are similarly aggressive. Paper wasps are less aggressive unless directly threatened. Our identification guide explains behavior differences.

QUESTION:Can I remove a hornet nest myself?

ANSWER:DIY hornet nest removal is extremely dangerous and not recommended. Hornets aggressively defend nests, and disturbing them can trigger mass attacks. Professional removal uses protective equipment, specialized products, and safe techniques. Attempting DIY removal often results in stings and incomplete removal. Our professional removal service ensures safe, complete elimination across Washington, Idaho, Oregon, and Arizona.

QUESTION:What happens to hornet nests in winter?

ANSWER:Hornet colonies die after first hard frost. Only fertilized queens survive winter by hibernating in protected locations (tree bark, attics, wall voids). Old nests are abandoned and not reused. Queens emerge in spring to start new colonies. Empty nests can be safely removed in winter. Our overwintering guide explains seasonal hornet behavior.

QUESTION:How do I know if a hornet nest is active?

ANSWER:Active nests show constant hornet traffic (workers entering/exiting), especially during daylight hours. Watch from a safe distance (20+ feet) for 10-15 minutes. Inactive nests show no activity and may have holes or damage. Never approach closely to inspect-use binoculars. Our professional inspection safely determines nest activity across Washington, Idaho, Oregon, and Arizona.

QUESTION:Do hornets reuse old nests?

ANSWER:No, hornets do not reuse old nests. Each spring, queens build new nests. However, favorable locations may attract new queens to build nearby. Removing old nests in winter prevents new queens from building in the same area. Our preventive treatments discourage nest building in problem areas.

QUESTION:What should I do if I find a hornet nest near my home?

ANSWER:Keep people and pets away from the nest area (20+ feet minimum). Do not disturb, spray, or throw objects at the nest. Avoid mowing or using loud equipment nearby. Contact professional pest control immediately for safe removal. Our emergency hornet removal provides rapid response across Washington, Idaho, Oregon, and Arizona.
