Which type of cricket is NOT commonly considered a household invader?

The gecko cricket is not commonly considered a household invader primarily because it is not typically found indoors in human habitats. This type of cricket is more often associated with specific outdoor environments, especially in warmer climates. The habits and behaviors of gecko crickets do not lead them into houses or buildings in the same way that other types of crickets, like house crickets, camel crickets, and field crickets, do.

House crickets, for example, are well-known for venturing indoors in search of warmth and food, making them common household pests. Camel crickets tend to inhabit basements and other damp areas within homes. Field crickets can also find their way inside, especially during the fall months when they seek shelter from the cold.

In summary, the gecko cricket's environmental preferences and behaviors distinguish it from other cricket types that are more likely to invade homes, making it the correct choice in this context.
