Dear What’s that Bug,
Being from Georgia I am used to hearing insects chirping at night and even bullfrogs doing their thing in the backyard. I am fond of these sounds and find them relaxing. And I know that having a cricket inside is supposed to be good luck. (Or is it just good luck if it is in your closet?)
However, the cricket or other chirping insect that is currently residing in my bathroom is not making me happy or relaxed. In fact, it is getting on my nerves and disturbing my sleep. I want to know what I should do. I don’t want to hear this sound that sort of echoes around in my empty bathroom but I don’t really want to kill this bug, nor would I really know how.
I have not spotted the bug, but it is really making it’s presence known. Any advice?
There are many folk beliefs in existence about crickets. Their presence in the home is generally thought to be an omen of good fortune in many parts of the world, and in China they are kept in captivity. The Chinese also match crickets for combat in a sport that is as popular there as cock fighting is in other countries. Extravagant wages are made on the outcome of championship fights.
The most common species in Southern California is the Tree Cricket (Oecanthus sp.) which is generally found in gardens and is almost always heard and not seen. They are usually green or white in color and only about 1/2 an inch long. It is common knowledge that the chirp rate of this cricket varies with the surrounding temperature, increasing at higher degrees and decreasing at lower ones. This fact has inspired formulas for calculating the temperature from the number of chirps per minute. The Snowy Tree Cricket, also called the Thermometer Cricket (Oecanthus fultoni) indicates the temperature in degrees Fahrenheit if one counts the number of chirps in 13 seconds and adds 40.
Your tenant is, however, more likely another type of cricket. Field Crickets (Gryllus sp.) are much larger than tree crickets, with body lengths up to 1 1/4 inches. Field Crickets live on the ground in fissures and under litter, vegetation and stones. They sometimes sing in the morning or late afternoon, but more usually at night when they come out to feed on all sorts of organic matter. They occasionally enter homes and become a nuisance by their unwelcome presence and incessant chirping.
A third possibility is that you are hosting a European House Cricket (Acheta domesticus) which are about 3/4 inch long as straw-brown in color. The species was apparently introduced into the eastern United States from Europe, although its original home may have been Africa. It has since become widespread in Southern California, where it is usually associated with human habitations. Lacking a dormancy period and hence being easy to raise, it is sold as fish bait and animal food in pet stores. Its chirp is frail and attracts less attention than that of its Field Cricket relatives. Bathrooms and kitchens are the most likely places to find crickets in the home.
I once had one who lived in the drain of my bathroom sink and I found its chirping to be quite soothing. I think you should lighten up and surrender to the sounds of nature.
