Natural Moth Repellents: Neem, Cedar and Lavender — Do They Work?

Neem leaves, cedar blocks and lavender sachets are popular in cupboards.

The short answer

These materials may deter moths mildly through smell, but effects fade and they do not kill larvae or eggs already present. They can be a pleasant addition to clean storage but not a substitute. Wash clothes, use airtight containers and refresh herbs or oils regularly.

What they do

• Mild deterrence while the scent lasts.
• Pleasant smell.

What they don't do

• Kill larvae or eggs.
• Protect dirty or soiled clothes.

Use them well

1. Start with clean, dry clothes.
2. Use airtight containers.
3. Refresh herbs, blocks or oils regularly.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
