A
American Cockroach (Periplaneta americana)
The American cockroach, also called the palmetto bug, is one of the largest cockroach species and a serious household pest throughout the U.S. It thrives in warm, moist environments such as basements, sewers, and kitchens, where it contaminates food and surfaces with bacteria and allergens. Its rapid reproductive cycle makes infestations difficult to control without professional intervention. Integrated pest management combining baits, exclusion, and residual sprays delivers the most effective results.
