Mothballs in the Garden: Not Labeled, Not Recommended

A gardener uses mothballs around the garden perimeter and asks how far to place them to avoid soil contamination. Expert advises: keep 1 foot away, but better yet, don't use them.

Why Avoid Mothballs

• Not labeled for garden use.
• Contain naphthalene or paradichlorobenzene—can contaminate soil and water.
• Choose EPA-registered repellents labeled for perimeter use instead.

Safety and legality favor approved products.
