Which of the following is a major structural pest commonly found in Utah?

Carpenter ants are indeed considered a major structural pest in Utah. These insects are known for their ability to damage wooden structures, as they excavate tunnels for nesting within the wood, consequently compromising the integrity of buildings. They thrive in moist environments, which makes certain areas in Utah particularly susceptible to infestations.

Although other pests like termites are also significant threats to structural integrity, carpenter ants are often more prevalent and identifiable in residential and commercial settings in the region. Their presence can indicate moisture problems in wood structures, requiring prompt attention to prevent further damage.

Other options, while they are pests, do not fit the criteria of being a major structural pest in Utah in quite the same way. Bed bugs are typically associated with human habitats and fabric materials rather than structural damage. German cockroaches are primarily a health concern and found more in indoor environments, whereas termites, although they do pose a significant threat, might not be as commonly reported in structural assessments as carpenter ants in Utah. Thus, carpenter ants hold their position as a prominent and widely recognized structural pest in this context.
