Adult Cockroaches

Adult cockroaches vary in size according to species. American and Oriental cockroaches are the largest cockroach species in most areas as both exceed an inch in length as adults. German and brown-banded cockroaches are generally about a half-inch long. The American cockroach typically lives the longest, with a lifespan often lasting up to three years from egg to adult. Oriental cockroaches frequently live longer than a year as well, while the life expectancies of German and brown-banded species usually fall within a year or less. Because adult female cockroaches produce egg cases repeatedly over relatively short lengths of time throughout their lives, professional pest control services often represent the best option for eliminating infestations caused by the fast reproductive potential of cockroaches.
