When bed bugs (Cimex lectularius) have adequate available blood sources they also have a shorter lifespan. Bed bugs who feed regularly have a lifespan of ten months, while those without adequate feeding can live a little more than a year. If a blood host is available, bedbugs can live to see three generations of offspring ready willing and hungry to prey on their human hosts.
Bed bugs (females) deposit three to eight eggs at a time. A total of 300-500 eggs can be produced by a single bug. Their eggs are 1/25″ long and curved. They are often deposited in clusters and attached to cracks, crevices or rough surfaces near adult harborages with a sticky epoxy-like substance.
Eggs typically hatch in a week to 12 days. The freshly hatched nymph is beige-colored before feeding, and then turns a redish color after getting a blood meal. There are 5 nymphal stages for bed bugs to reach maturity, which usually takes about 32-48 days. Adult bed bugs can survive for up to seven months without blood and have been known to live in empty buildings for up to one year.
