In 2005, GTO was founded by Per Roennau, who had the early vision of offering the PCO industry non-toxic alternatives to the traditional pest control. His vision was supported in the following years by authority demands from the EU, who aimed to protect the environment and limit escalating problems with rodenticide resistance by bringing the focus onto reducing the amount of rodenticides used.


The current GTO system has been in operation since 2010 both in Denmark and throughout the world.


In 2015, to ensure a generational change in GTO, as well as reinforce rollout worldwide, Per Roennau sold the company to the multi-industrial investor, Coreprax. The change in ownership consolidates GTO’s position as one of the definers of future industrial standards.
