The American cockroach (Periplaneta americana) is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. It is often misidentified as a palmetto bug.Despite their name, American cockroaches are native to Africa and the Middle East. They are believed to have been introduced to the Americas only from the 17th century AD onward as a result of human commercial patterns, including the Atlantic slave trade.

The region is serviced by the Lehigh Valley International Airport which has seen steady growth in passenger traffic and rapid growth in the transportation of air cargo where, as of 2020, it flies more than 210 million pounds of cargo annually with an increase of nearly 166% in cargo tonnage shipped between 2015 and 2016 alone.
