Cockroaches live in groups called aggregations.
They grow by incomplete metamorphosis, beginning with an egg. These eggs are not easily affected by insecticides. From the egg hatches a nymph, which looks like a small adult without wings. Nymphs move out in search of moisture, harborage, and food, so sighting these your cockroaches may indicate that the population is growing. After numerous molts, a nymph becomes and adult.
