Which of the following is not included in the household pest category?

The classification of household pests typically refers to organisms that are commonly found within residential environments and have a direct impact on the occupants, property, or both. Cockroaches, spiders, and fleas are frequently encountered pests in households, posing potential health risks and nuisance to residents.

Wood destroying organisms, however, are generally categorized separately from household pests. This group includes termites, carpenter ants, and other insects that primarily cause damage to structural components of homes rather than being direct nuisances or health threats to the occupants. Their impact is more about structural integrity than day-to-day interactions within the living space.

Therefore, the classification of wood destroying organisms as not part of the household pest category is correct, as it emphasizes the distinction between pests that invade living spaces and those that primarily affect the structure of a home.
