What are the best insect repellents for cedar outdoor tree boxes?

Cedar outdoor tree boxes are a beautiful addition to any garden, but they can attract unwanted pests. To keep insects at bay, consider using the following repellents:

1. Natural Oils: Essential oils like cedarwood, neem, and eucalyptus are effective and eco-friendly. Mix with water and spray on the boxes.

2. Diatomaceous Earth: A non-toxic powder that deters insects by damaging their exoskeletons. Sprinkle around the base of the boxes.

3. Commercial Insect Repellents: Look for products containing permethrin or pyrethrin, which are safe for plants but lethal to pests.

4. Vinegar Solution: A mix of vinegar and water can repel ants and other small insects.

5. Physical Barriers: Use fine mesh or copper tape to block crawling insects.

For long-term protection, reapply repellents regularly and maintain proper drainage to avoid attracting moisture-loving pests. Combining natural and chemical methods often yields the best results.
