Can Dogs Eat Mothballs? No — Even One Causes Serious Poisoning

This food is NOT safe for dogs. Keep it away from your pet.

Mothballs are highly toxic to dogs. Both naphthalene and paradichlorobenzene types cause serious poisoning. Even the fumes from mothballs cause respiratory irritation and neurological damage with prolonged exposure.

Warning Signs & Symptoms

Vomiting, lethargy, pale or brown gums, seizures, liver damage, kidney damage, hemolytic anemia.

If Your Dog Ate This

Call vet or ASPCA Poison Control 888-426-4435 immediately.

What to Avoid

all mothball products — naphthalene and paradichlorobenzene types

Preparation & Serving

Call vet or ASPCA Poison Control 888-426-4435 immediately. Fresh air if fume exposure. Do not induce vomiting without vet guidance.

Did you know?

Mothballs work by sublimating — turning directly from solid to gas — releasing vapors that are toxic to moths and larvae. This same property makes them continuously dangerous in enclosed spaces as the vapor concentration builds up affecting dogs even without direct ingestion.

What You Need to Know

Naphthalene mothballs are more toxic than paradichlorobenzene types but both are dangerous. Ingestion of even one mothball causes serious toxicity. Fumes in an enclosed space cause respiratory irritation and neurological effects. Dogs that sleep in areas where mothballs are stored are at risk from chronic low-level exposure even without direct ingestion.
