Spotted lanternflies may look like beautiful bugs with their bright red wings and speckled patterns, but these invasive pests are causing major damage to trees, plants, and crops across many states. If you’re a dog owner, you might be wondering: Are spotted lanternflies dangerous to dogs? And what should you do if your pup decides to snack on one?

Here’s what you need to know to keep your furry friend safe during lanternfly season.

What Are Spotted Lanternflies?

Spotted lanternflies are invasive insects originally from Asia that have spread throughout the northeastern U.S., especially in states like Pennsylvania, New Jersey, and Virginia. They feed on the sap of trees and plants, leaving behind a sticky substance called honeydew, which can promote mold growth and attract other pests.

While they don’t bite or sting humans or pets, their growing population has made them an everyday nuisance — especially if your dog loves chasing bugs.

Are Spotted Lanternflies Harmful to Dogs?

Good news: spotted lanternflies are not known to be toxic to dogs. Most dogs that eat one or two may not experience any symptoms at all. However, eating several at once or ingesting them regularly could lead to:

  • Mild gastrointestinal upset, like vomiting or diarrhea
  • Drooling or pawing at the mouth, due to the taste or texture
  • Allergic reactions in rare cases

If your dog eats a spotted lanternfly and seems totally fine, there’s usually no reason to worry. But if they show signs of illness — or you know they’ve eaten a large number — it’s always best to call your vet for advice.

What Should You Do If Your Dog Eats One?

If your dog chomps down on a lanternfly:

  1. Don’t panic. One or two usually won’t cause any serious harm.
  2. Watch for symptoms. Keep an eye out for vomiting, excessive drooling, or changes in behavior.
  3. Call your vet if needed. If your dog eats a lot of them, or if symptoms persist, get professional advice.
  4. Clean paws and fur. If your dog walks through areas where lanternflies are crushed or where honeydew is present, give them a quick wipe-down to prevent skin irritation.

How to Protect Your Dog

  • Avoid infested areas. Stick to well-maintained trails and avoid wooded spots known for high lanternfly activity.
  • Supervise backyard time. Especially if you’ve noticed lanternflies in your neighborhood.
  • Teach the “leave it” command. This can be a lifesaver when your dog spots a new “toy” crawling on the sidewalk.
  • Control lanternflies safely. Avoid using chemical insecticides in areas your dog plays — opt for pet-safe options or manual removal instead.

Final Thoughts

Spotted lanternflies are a growing environmental issue, but thankfully, they don’t pose a serious threat to your pup. A little vigilance goes a long way. If your dog does get curious and eats one, stay calm, monitor them closely, and contact your vet if anything seems off.
