World Pest Control

From Tardis Wiki, the free Doctor Who reference

World Pest Control was an Earth organisation which manufactured pesticides. Their offices were located outside a jungle. In 2035, John and Gillian asked them for help when their grandfather was captured by the Caterpillar Men. They sent a helicopter which sprayed the base with pesticides lethal to insects but harmless to humans. (COMIC: The Caterpillar Men)
