What is the most effective way to prevent arthropods from entering billets?

Using screens is the most effective way to prevent arthropods from entering billets because they create a physical barrier that restricts access while still allowing for ventilation. Screens can effectively block various types of insects and other small pests from entering living quarters or work areas without compromising airflow, which is essential for maintaining comfort and hygiene within the billet.

In contrast, while netting can also serve a similar function, it may not be as effective in blocking smaller insects compared to finer screens. Traps can help reduce arthropod populations once they are already inside but do not prevent entry. Pesticides can control pests but may pose health risks to personnel and the environment and are not a long-term preventive measure. Screens provide a sustainable and low-risk solution to keeping arthropods out.
