Crickets typically live for about 8 to 10 weeks as adults, though this can vary depending on species and environmental conditions

. Some sources note an average lifespan around 90 days (about 3 months)

. The house cricket, a common species found indoors, usually lives 8 to 10 weeks but can survive up to 8 months under optimal conditions

. Other species vary widely; for example, Jerusalem crickets may live up to 4 years, and cave crickets about 1 to 2 years

. Crickets undergo three main life stages: egg, nymph, and adult. Eggs hatch in soil, and nymphs mature over several weeks before becoming adults. The lifespan of crickets is influenced by temperature, predation, and food availability. Warmer climates speed up their lifecycle, while cold weather often kills adults, especially outdoor species like field crickets which die off by winter

. In captivity or warm indoor environments, crickets can live longer than in the wild, sometimes up to a year for house crickets

. However, in natural conditions, most crickets live only a few weeks to a few months. Summary:

• Typical adult cricket lifespan: 8–10 weeks (2–3 months)

• House cricket: 8–10 weeks average, up to 8 months indoors

• Other species: from weeks to several years (e.g., Jerusalem cricket up to 4 years)

• Influencing factors: species, temperature, predators, food availability

Thus, while most crickets live a couple of months as adults, lifespan varies widely by species and environment.
