Not all of them can produce sound, but when they do, it is the adult male that produces sound by rubbing his wings together. The male cricket uses sound to attract females, or sometimes to sound an alarm when he is disturbed.
In some Asian countries crickets are kept in small cages in homes where they are prized for their cheerful songs. However, when crickets enter buildings uninvited, many people find those pleasant sounds annoying, and sometimes, crickets can damage a wide variety of materials.
The information presented here will help you understand more about why and how crickets move indoors and how you can best prevent that from happening. Many crickets are attracted to areas where the moisture level is high and stable. They often move inside accidentally when a door or window is left open or sometimes in the fall when the temperature gets cooler. All crickets have chewing mouthparts.
Usually they feed on decaying leaves, living plants, or even on other insects. Indoors, crickets can feed on fabrics, leather, and fur, and are especially likely to feed on items soiled with food, beverages or perspiration. They feed on the surface of fabrics, such as cottons, silks or woolens, leaving roughened areas caused by their picking and pulling to loosen fibers.
Two common crickets that occasionally become pests are the house and field crickets. Both the house and field crickets have slender antennae that are longer than their bodies. They have large hind legs to help them jump. Their legs have short, sharp spines on them. Females and males have long antenna-like feeler at the end of their body and females also have an egg-laying guide.
The adults and their young look alike, except the young are smaller and have no wings. House crickets are one inch or less in length and hold their wings flat over their backs. They are yellowish-brown in color with three dark stripes on the head. Field crickets eat a variety of different plant species mostly weed and will also occasionally feed on insects. I have a rock pile in a section of my yard a future wall if I ever build it!
Slightly smaller and lighter brown in color, this species does very well living inside buildings. In fact, one of my earliest memories dealing with this species as a pest was in one of the dining halls at my alma mater UNH. The house cricket is typically straw-colored with red to brown markings. On the head, there are two dark bars. Males produce a faint triple chirp sound when wanting to attract a mate.
Field Crickets are much darker in color, from dark reddish to brown to even black coloration. This species is typically found during summer and fall months when nights reach 77 degrees or warmer. They are common pests in and around homes or businesses that back up to or are surrounded by grassy habitats. Most crickets are found in the garage and in wall voids in the basement.
Any crack or crevice around the foundation, including the cracks in unsealed windows and doors, provides easy entrance for crickets.
To keep crickets and other insect pests out, make sure the foundation is sealed correctly and all doors and window seals are tight. Field crickets in the genus Gryllus are usually shiny black, and the different species are often best separated by singing pattern.
Right to Use. There are several species of field crickets that are blackish, and they can be hard to tell apart. This is one of the more common species, Gryllus pennsylvanicus. The house cricket, Acheta domesticus, is light brown or tannish overall; the tan head has three dark crossbands.
This is a female cricket: You can tell because she has an ovipositor at the tip of her abdomen. House crickets and field crickets share in common large heads, hind legs adapted for jumping, and stout, unmovable spines on the hind legs. They are common in many habitats, especially grassy areas such as lawns, fields, pastures, prairies, roadsides, but also in woods.
Male crickets chirp by rubbing rough portions of their wings together; by raising the wings at an angle, they form a resonating chamber sort of like a violin body. The calls attract females and also warn off rival males. House crickets are probably native to Eurasia but are found nearly worldwide, having traveled the globe with people.
They eat a wide variety of foods and can be kept as pets. Similar Species. Camel Crickets Cave Crickets. Tree Crickets. Short-Horned Grasshoppers. Differential Grasshopper.
