Female house crickets will lay from 50 to 100 eggs during her life. She lays eggs individually, rather than in rafts like mosquitoes. Eggs are deposited in cracks inside and in soft, moist soil outdoors. It takes eggs a couple of weeks to hatch. Egg hatching is not seasonal. You can find nymphs year-round. They don't have any special over-wintering stage they go into like some insects. Instead, in colder months house crickets will find warm places to hide inside buildings. Their country cousins stay warm hanging around dumps or compost piles where fermentation heat keeps them alive.
