What do crickets eat?  Well, that depends on the cricket.  There are many different species that feed on a variety of things.  Crickets are generally considered a pest because of their chirping noise and the damage they can do to some items found in your home.

Crickets that make their way into your home will feed on a variety of food, paper products and fabrics.  Most often this can include cotton, wool, linen, nylon, rayon, furs and silk as well as wallpaper, book bindings (they're really after the glue), vegetables, fruit, meat and sometimes even other crickets.  Below are a few species looked at in more detail.

Still wondering, “What do crickets eat?”  They are scavengers and omnivores and to sum it up they feed on decaying plants, fungi, organic materials, vegetables, fruits, paper, clothing, rubber, wood and each other.  Crickets are a food source for lizards, frogs, spiders, tortoises and salamanders.

What's With All That Chirping?

It is interesting to note that only male crickets chirp.  They have a large vein that runs down the bottom of their wings that has “teeth” resembling a comb.  The chirp is a result of them rubbing their wings together.  Many people think the sounds come from the rubbing of their legs but that is only a myth.

Crickets produce a few types of songs.  The first one is a song that repels males but attracts the females and it is extremely loud.  The second is a courting quiet song when the female is close.  A very aggressive song may be triggered if they detect another male is coming close and finally, a copulatory song is sang after the male has successfully released sperm onto the female eggs.

Crickets will chirp, depending on species, environment and temperature, at different rates.  Usually, the warmer it is, the faster the chirp.  This chirping rate is given the name of Dolbear's Law.  These are a cold blooded species and take on their surrounding temperature so like other creatures of this type, the temperature has a direct chemical reaction with their body.

Crickets are sometimes kept as pets and in some countries they are considered good luck.  Brazilian folklore believes the chirping is a sign of rain and they can predict the weather.  There are also those that believe a cricket is a sign of money coming and they are always a symbolic species in movies representing night fall.
