How to identify Crickets
Part of the Grylloidea superfamily of insects, crickets have prominent hind legs and long antennae often greater than or equal to the length of their bodies. The notable antennae help distinguish crickets and grasshoppers, which otherwise bear a striking resemblance to each other. Adult crickets usually measure between 12 mm and 25 mm in length, depending on the species. Crickets range in colour from light yellow or tan to dark brown or black. Many cricket species have wings that lay flat against the back, though some varieties of crickets are wingless. Adult females visibly feature an ovipositor, a long appendage shaped like a needle or sword and used for laying eggs.
How to prevent Crickets
Seal cracks and crevices in walls and foundations, seal cracks and crevices around door and window frames, ensure door and window screens are in good condition and not torn, clean up clutter and debris, listen out for cricket chirps, ventilate your crawl space, reduce moisture sources around your home or facility.
Habitat, Diet, and Life Cycle
Crickets usually behave nocturnally and are most active at night. During the day, crickets typically find a dark, moist place to rest and hide from predators. The insects live in a variety of habitats, including fields, trees, burrows, caves and even garbage dumps. As the weather turns colder, crickets often take refuge in manmade structures like houses and sheds. Some common species of crickets demonstrate a strong attraction to light.
Harmless to humans, crickets mainly feed on plants and plant debris. Most crickets are omnivorous and also eat smaller insects, including other crickets. When crickets manage to invade private residences, they often consume fabrics, houseplants, paper products and remnants of human food.
Winged male crickets initiate the reproductive process by rubbing their wings together to produce distinctive chirping noises that attract female crickets. Females use their ovipositor to lay eggs primarily during the autumn season. Cricket eggs mature during the winter and hatch in the spring. Baby crickets emerge from the eggs as nymphs with underdeveloped wings before gradually evolving into adults. In Canada and other northern regions, crickets produce just one generation of offspring each year. Crickets rarely breed indoors.
