I googled the lifespan of the cricket.
copy/pasted:
Crickets only live a few weeks. The crickets hatch from eggs laid in the ground in the spring or early summer, and are adults within about 3 months. They breed and then lay their eggs in late summer. They then die of old age or will freeze if the temperature lowers to 32 degrees. Incidently the the higher the temperature gets the more a cricket chirps.

Try turning on your airconditioner if you have one and maybe he'll quiet down...lol.
