The answer to 'what is cricket' is a type of insect that is commonly found in homes. Crickets are small, brown or black insects with long, slender legs and antennae. They are known for their distinctive chirping sound, which is made by the males to attract females. Crickets are typically harmless to humans, but they can be a nuisance if they invade your home in large numbers.
Crickets are omnivores, meaning they eat both plants and other insects. They are often found in damp, dark areas of the home, such as basements, crawl spaces, and around plumbing fixtures. Crickets can also be attracted to sources of food, such as crumbs or spills, and may come inside through cracks and crevices in the home's foundation or exterior.
