Why High Heat Steam for Bed Bugs?

Most toxic insecticides are non-ovicidal, which means they do not kill eggs so it’s no surprise that re-infestation often occurs soon after a chemical treatment (10-14 days).


Greenleaf can eradicate a wide range of pests with high heat steam: including the very persistent bed bug, fleas and dust mites. Green Leaf’s techniques are effective against the most severe infestations and high heat steam isn’t selective therefore you also have the benefits of the high heat steam killing viruses, germs and bacteria. High heat steam is pure water and air so it is 100% safe for you and for the environment.




Temperatures above 45?C will kill bed bugs – but the heat must be applied properly and long enough to each area. At Green Leaf, we treat infested areas with temperatures above 100?C of high heat steam at a minimum flow rate, to ensure bugs aren’t blown around. It kills bed bugs, bed bug eggs, fleas and dust mites instantly, yet also cools to the touch within seconds so no damage is caused to surfaces.




It’s common for eggs to start hatching within 10-14 DAYS after a chemical treatment – This is because chemical insecticides are non-ovicidal, which means they do not penetrate and kill eggs. High heat steam on the other hand, heats pests and their eggs to temperatures which instantly destroy them. Chemical treatments rely on a living pest to inhale/absorb their mostly dangerous compounds. This method kills pests more slowly and has no impact on the embryos within eggs. If no active chemical residual is present when these eggs hatch, the breeding cycle continues. The most recent research from leading Bed Bug Specialists (Dr. Potter, Dinni Miller, Dr. Dogget & Rick Cooper) shows us that the common pesticides in Canada that have bed bugs on their label only have low kill rate on adult bed bugs. In fact some are very resistant to the pyrethroids we have registered (reference: Romero, A., M.F. Potter, D.A. Potter and K.F. Haynes. 2007. Insecticide resistance in the bed bug: a factor in the pest’s sudden resurgence? J. Med. Entomol. 44 (2):175-178).


Greenleaf’s high heat steam kills all five nymph stages of bed bugs – including the eggs – bringing an end to the breeding cycle. Bed bugs are small, thin, and often hide in the narrowest of cracks. In other words, out of reach of most chemical treatments. High heat steam is capable of reaching just about anywhere – so bed bugs have nowhere to hide.




Areas that cannot be addressed with high heat steam such as electrical outlets, fire alarms; light switches etc. as well as where the floor and wall meets, corners, cracks and crevices of box spring and other furniture in the room will be treated with Diatomaceous Earth a non-toxic pesticide that consists of fossilized remains of diatoms a type of hard-shelled algae. It works as a desiccant; it’s a mild abrasive components scratch the outer layer of the insect when it comes into contact with the powder. The bed bug receives several tiny scratches on its surface therefore not allowing it to retain moisture – without the capability of retaining moisture bed bugs cannot survive and cannot pro-create.


Mattress and box spring are sealed with bed bug proof encasements and bed/couches are left with The Bed Moat monitors for ongoing detection.
