Lizard Repellents: Eggshells, Pepper, Naphthalene and Other Claims

Many home tricks claim to drive lizards away. Few are proven, and some are unsafe.

The short answer

Eggshells, pepper spray and garlic are popular but have little evidence. Naphthalene balls are toxic and should not be used where people, children or pets or food are present. Better results come from reducing insects, sealing gaps, keeping food covered and cleaning. If lizards are a persistent concern, ask a professional.

Claims

• Pepper or garlic sprays: mild at best, can irritate.

When to call a professional
