How cockroaches could save lives
The heaviest, the subterranean rhinoceros cockroach, weighs in at 35g, measures 8cm in length, and lives in Australia. One of the smallest is a pest commonly found in Europe and North America - the German cockroach, which is just over 1cm long. Martina and her grandma might be interested to know that coffee grounds are often used as bait to trap them.
