True or False: Pest exclusion techniques are primarily effective against larger pests.

Pest exclusion techniques are indeed effective against larger pests. These methods involve sealing entry points and barriers to prevent pests from entering a space, which is particularly effective for larger pests like rodents and other animals that can fit through openings. The concept of exclusion encompasses a range of strategies aimed at preventing pests from gaining access to buildings, gardens, and other areas, thus reducing the likelihood of infestations.

While exclusion can also help manage smaller pests, such as certain insects, its primary focus tends to be on larger pests that are more easily deterred by sealed spaces. The effectiveness of exclusion diminishes for very small insects that can infiltrate through smaller cracks and openings. Thus, by focusing on the physical barriers created by pest exclusion techniques, the main advantage is the prevention of access for larger pests.
