Who is the biggest pest control company?

The biggest pest control company in the world by revenue and global footprint is generally considered to be Rollins Inc and Rentokil Initial competing for top position, with recent rankings placing Rentokil Initial as the largest after its acquisition of Terminix in 2022. Rollins Inc owns brands such as Orkin, Western Pest Services, and others and has extensive operations in North America and internationally. Rentokil Initial, headquartered in the UK, operates in many countries and owns Terminix, Ehrlich, Western Exterminator, and Presto-X, giving it massive scale.

Other large players include Ecolab, which has a significant pest elimination division focused on commercial clients, and Anticimex, which is large in Europe. In the United States specifically, Terminix and Orkin are the two most recognized residential brands. Rankings can change year to year based on acquisitions and currency fluctuations, but as of recent years Rentokil Initial and Rollins are the two largest pest control companies globally, with Rentokil often cited as the largest after the Terminix acquisition significantly increased its North American market share.
