Earwigs live about one year from hatching. Mating occurs in the fall, at which time you can find the males and females living together in ground debris, in crevices, or in the soil. Eggs are laid in late winter or early spring, which hatch in about seven days into nymphs that are smaller versions of adult insects. Through a series of molts, the nymphs gradually transform into adults, which will mate in the fall. The previous generation typically dies out sometime during the growth of the nymphs into adults. Warm climates may see two generations of garden earwigs each year. Because cold weather kills off most earwigs, relatively few mating couples survive the winter to reproduce. Thus, this is not an insect that is usually found in large numbers in cooler climates.
