πŸ”‘ Key Difference

Bald-faced hornets: large black and white wasps that build enclosed gray paper nests β€” the classic 'hornet nest' shape. Aggressive defenders. Paper wasps: smaller, build open umbrella-shaped comb nests under eaves. Much less aggressive.

⚠️ Urgency

Bald-faced hornets near traffic areas warrant treatment (very aggressive). Paper wasps in low-traffic locations can often be left β€” they provide caterpillar pest control.

πŸ”§ Getting the Treatment Right

Correct identification before treatment is essential β€” using the wrong product or approach wastes time and can mask the real problem. If you cannot confidently identify the pest from the comparison above, a professional inspection is the fastest path to the right answer.

πŸ’‘ Capture method: Place a clear plastic cup over the pest and slide a card underneath to trap it. A photo submitted to your local cooperative extension service can get you a free expert ID.

❓ Identification FAQ

What's the fastest way to confirm which pest I have?
Capture a live or dead specimen and compare it directly against the identification features in this guide. A clear close-up photo submitted to your county's cooperative extension service will get you a free expert identification within 1–3 business days. iNaturalist is also excellent for invertebrate ID.
Can I treat for both at the same time?
If you're unsure which pest you have, it's often more effective to wait for confirmation rather than applying multiple treatments. Misapplied pesticides can scatter populations without eliminating them. The exception: if both pests require identical treatment (as with many fall invaders), treating once covers both.
