What are nuisance pests?

Nuisance pests are defined as those that do not cause significant damage to structures, crops, or health but are problematic and bothersome to people. They may create discomfort or anxiety due to their presence, such as mosquitoes that can disrupt outdoor activities or ants that invade homes in search of food. These pests don't usually pose a direct threat to health or property but can lead to irritation and annoyance.

The other options reflect different categories of pests or important distinctions. For instance, some pests may be targeted for immediate eradication due to their potential to cause harm, while others may play a crucial role in the ecosystem, contributing positively to environmental balance. Additionally, the notion of seasonality applies to some pests but does not define nuisance pests as a whole. Thus, the correct answer accurately captures the essence of nuisance pests and their impact on human comfort.
