Untreated wood carvings are vulnerable to insect damage, but there are effective, natural ways to protect them without harsh chemicals. Here are the best methods:

1. Regular Cleaning and Dusting: Insects are attracted to dirt and debris. Wipe carvings with a dry cloth weekly to remove dust and potential insect eggs.

2. Sunlight and Airflow: Place carvings in well-ventilated areas with indirect sunlight. UV rays and airflow deter pests like termites and beetles.

3. Natural Oils and Waxes: Apply linseed oil, beeswax, or cedar oil to create a protective barrier. These repel insects while enhancing the wood’s appearance.

4. Freezing Method: For small carvings, seal them in a plastic bag and freeze for 48 hours to kill larvae or eggs.

5. Herbal Repellents: Use sachets of lavender, cloves, or neem leaves near carvings. Their strong scents naturally deter insects.

6. Saltwater Solution: Lightly spray a diluted saltwater mix (1 tbsp salt per cup of water) to discourage pests without harming the wood.

7. Elevate and Isolate: Keep carvings off damp surfaces and away from infested areas to reduce exposure.

By combining these methods, you can preserve untreated wood carvings sustainably. Regular inspections and proactive care are key to long-term protection.
