These pests can invade homes and buildings in rare occasions. They have a hard time reproducing indoors and they prefer to be outside. When the weather is severe they try and find a more structured shelter which can end up being your home or building.
To detect whether you may have crickets, check areas that are warmer for example the stove or by a heater. If you have a large infestation of crickets they can actually do damage. They tend to eat anything from clothes, paper, to organic materials.
