The chirping noises of crickets can be quite irritating to people who are trying to sleep at night. This is because crickets are nocturnal insects that make their sounds by rubbing their wings together, a behavior known as stridulation. The chirping is done in order to attract a mate, to defend their territory from predators, or to warn other male crickets of an approaching female.
Crickets live virtually everywhere from caves to deserts, forests, grasslands, wetlands, and even beaches. They are most active at night and in the summer. They are solitary creatures and spend most of their time in holes or burrows.
In addition to their chirping for mating purposes, crickets also use their songs to communicate with other crickets and other animals in the area. A cricket’s song can tell you the temperature of the environment as the tones and tempo change with changes in air temperatures.
While they live primarily outdoors, crickets occasionally enter houses to escape extreme weather conditions or to run away from predators. They can easily enter through open doors and windows, as well as through cracks in the foundation and exterior walls.
To keep crickets out of your home, make sure that your doors and screens are tight-fitting. Repair any broken screens and keep windows shut, especially at night. Make your home unappetizing to crickets by eliminating food and water sources around the house, keeping garbage bins covered, and removing plant debris from the yard. Also, regular mowing and trimming of bushes and trees will help eliminate areas where crickets may hide.
