WDO Home Inspection Practice Exam 2025 – Comprehensive Prep Guide

When considering methods for controlling carpenter bees, the option of painting surfaces with latex paint is indeed the least effective choice. Carpenter bees are known for their nesting behavior, where they bore holes into untreated wood to lay their eggs. While painting surfaces may help protect wood from moisture and decay, it does not directly address the nest infestations or deter the bees themselves.

Applying latex paint can provide a barrier to some degree, potentially making it harder for bees to bore into the wood. However, if the wood is already infested or has existing nests, painting it will not eliminate the existing bees. Furthermore, carpenter bees often prefer untreated or weathered wood surfaces, so even a coat of paint might not be sufficient to prevent them from returning to an area where they previously nested.

In comparison, methods such as insect sprays, filling holes with caulking material, and installing traps are more directly impactful in controlling carpenter bee populations. Insect sprays target the bees and can effectively kill them on contact or interfere with their life cycle, while sealing up holes prevents new bees from nesting in those sites. Traps are designed to attract and capture carpenter bees, offering another means of population control. These methods show a more proactive approach to managing the bees and their nests.
