Musty Cupboards: Insects, Mould or Both?

A musty smell in a cupboard usually means dampness, and sometimes pests.

The short answer

Mould creates musty smells and often comes with booklice, silverfish or mites that feed on it. Empty and air the cupboard, wipe with a suitable cleaner, dry thoroughly, fix leaks, add moisture absorbers and wash or dry-clean affected items. If it keeps returning, look for hidden damp.

Causes

• High humidity.
• Leaks or damp walls.
• Poor ventilation.

Cleanup

1. Empty the cupboard and air it.
2. Wipe with a suitable cleaner and dry fully.
3. Wash or dry-clean items.
4. Use moisture absorbers.
5. Leave gaps for airflow.

If it returns

• Check walls and plumbing.
• Use a dehumidifier.
• Seek professional advice.

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.
