Rentokil is a global pest control company based in the United Kingdom. Rentokil was established in 1927 and today operates in over forty countries. With its strength in Europe, Rentokil has expanded to large parts of the world, performing commercial and residential pest control. Rentokil is also innovative in technologies by developing new products for rodent control such as the trap which immobilizes rodents through battery electric charges. Rentokil has marketed this new technology extensively since 2009.

In North America, Rentokil has an established presence in the United States and Canada. There are also operations in the Caribbean and limited areas of South America. Specifically in the United States, Rentokil has expanded their market primarily through acquisitions. Originally branded as Rentokil in Georgia, expansion has been rapid for the company through specific regional companies.

Rentokil owns Watch-All, which covers Massachusetts and Rhode Island. J.C. Ehrlich, which was a regional company based in Reading, Pennsylvania, covers Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Ohio, Virginia, West Virginia, South Carolina, and Georgia. Presto-X, another large regional company previously with a commercial focus now part of Rentokil, covers Minnesota, South Dakota, Wyoming, Nebraska, Colorado, Kansas, Iowa, Missouri, Illinois, Indiana, New Mexico, Oklahoma, Arkansas, Tennessee, Kentucky, Alabama, Mississippi, Louisiana, and Texas. Currently, remaining states are not covered by Rentokil. In Canada, Rentokil has operations in Ontario, British Columbia, and Alberta.

Rentokil has traditionally focused on commercial services as that is the bulk of pest control demands in their home area of Europe, but with acquisitions of several American companies which had a strong residential emphasis, Rentokil now provides residential services as well. Rentokil employs over 96,000 employees worldwide in the forty plus countries where they operate. Most acquisitions at this point in the US, keep the original company name and do not market as Rentokil.
