Which of the following methods can reduce the risk of wood-destroying insect infestations?

Applying wood preservatives is an effective method for reducing the risk of wood-destroying insect infestations. Wood preservatives create a protective barrier that can significantly deter insects such as termites and other wood-destroying organisms from feeding on wood structures. These chemical treatments work by either repelling insects or making the wood less palatable for them, ultimately protecting the integrity of the wood.

In contrast, increasing ambient moisture can create an environment conducive to wood-destroying insects. Many wood-destroying insects, including termites, thrive in damp environments. Keeping wood and building materials dry is crucial for prevention.

Storing firewood indoors is also not advisable when it comes to preventing infestations. Firewood should be stored away from the home and off the ground to minimize the risk of introducing pests indoors. Proper storage helps reduce contact between firewood and the structure of the home.

In summary, applying wood preservatives effectively protects wood against insect damage, while the other methods can inadvertently increase the risk of infestations.
