What is the maximum size of openings into attic spaces to prevent entry of pests such as birds and rodents?

1. 1/16"

2. 1/8"

3. 1/4"

4. 1/2"

The correct answer is: 1/4"

The maximum size of openings into attic spaces to prevent the entry of pests such as birds and rodents is typically limited to a 1/4 inch opening. This size is small enough to deter most common pests while still allowing for necessary ventilation. Openings larger than this can become entry points for various wildlife, leading to potential infestations. It's essential in building design and construction to address pest control effectively through the use of properly sized openings. Smaller dimensions help create a barrier against undesirable animals that can cause damage to insulation, wiring, and other components within the attic space. This consideration is a critical aspect of maintaining the integrity and functionality of the building's structure.
