UK bed bug strains have developed measurable resistance to the pyrethroid insecticides that dominate the over-the-counter and trade markets. That's why so many properties get sprayed two or three times and the problem keeps coming back.
Heat is a physical kill, not a chemical one. Adults, nymphs and eggs all denature at 60.5–65°C core temperature, and there's nothing for them to build resistance to.
Our process is engineered to hit that core temperature in every void, seam and cavity in one visit.
