1924 A small company was set up by Harold Maxwell-Lefroy, professor of entomology at Imperial College London, and his assistant Elizabeth Eades who had developed an anti-woodworm fluid called Ento-Kill. Since a similar name had already been registered as a trade name, Lefroy instead named his insecticide Rentokil.

1925 Lefroy was killed in his laboratory (one source says due to exposure to insecticide; another says due to a fire); his assistant Elizabeth Eades took over the company. By providing a reliable service, the company soon started to grow.

1926 The Rentokil company was incorporated as a private company[1].

1939 When war broke out, measures were needed to protect the nation's dwindling food stores, which could not afford any losses to pests. Rentokil began offering its own extermination services.

In the post-war years, Rentokil continued to thrive, gradually expanding into other businesses.
