How do manufacturers ensure their products are resistant to pests like termites or rodents?

Manufacturers employ various strategies to ensure their products are resistant to pests like termites and rodents. One common method is using treated materials, such as pressure-treated wood infused with chemicals that repel insects. For metal or plastic products, structural designs may include sealed joints and barriers to prevent rodent entry. Additionally, some companies apply protective coatings or finishes that deter pests. Quality control processes often involve testing materials in pest-prone environments to verify durability. Sustainable alternatives, like naturally pest-resistant woods (e.g., cedar), are also gaining popularity. By combining these techniques, manufacturers create long-lasting, pest-proof products for consumers.
