Which of the following best describes an occasional pest?

An occasional pest is best characterized as one that appears intermittently rather than consistently. This variation in presence can be influenced by a range of factors including environmental conditions, seasonal changes, and the availability of resources such as food, shelter, and moisture. Unlike pests that are constantly present or that cause ongoing damage, occasional pests are often controllable and may not necessitate continuous management practices. This definition signifies that while they can pose a threat at certain times, their impact is not chronic or predictable, allowing for a more targeted and timely response when they do emerge.
