bed bug - alive because it hasn't met Mr Ozone yet.

I was recently asked by a customer if our ozone generators could kill bed bugs. I get asked this question often, so I thought I'd write an article on this subject of bed bugs and ozone.


The short answer is yes, but not with an ambient air ozone generator.  To kill bed bugs with ozone, you need to create ultra-high ozone concentrations with an oxygen-fed ozonator (1800 ppm) for 2 1/2 hours. PROOF. The problem is, and most ozone generator sells people won't tell you this, you can't achieve an 1800 ppm ozone concentration WITHOUT an oxygen-fed ozonator.  There isn't enough oxygen in the air to create 1800 ppm ozone from ambient air. Most ozone machines on the market that feature 100 CFM fans can only create 10-50 ppm ozone concentration in the air because they can't churn the air (you need 3000 CFM box fan to do that) and that's just not enough ozone to kill bed bugs.  That amount of ozone will, however, kill viruses, small parasites like mites, molds, and bacteria as well as permanently remove odors.  I've also found it kills flies, mosquitoes, moths, and tiny critters like crickets and roaches. Bedbugs? No. 


If you want to know how to kill bed bugs with ozone and without chemicals in a room, this is the protocol that I've used myself and know works:



1) First, apply diatomaceous earth (DE) where the walls meet the floors around the room. Next, apply DE behind all of the electrical faceplates.  (DE is non-toxic, harmless to humans and pets) 

2) Seal the cracks under the door and the vents with duct tape or towels, etc. 

3) Perform an ozone shock treatment.  Run for 15-30 minutes on, 1 hour off, 24 hours a day for at least seven days straight 

What this does is chase the bed bugs out of bed towards the walls and electrical sockets and over the DE.  The ozone shortens their life and kills x amount of bed bugs; the DE is the double whammy that seals their fate.  

Note: You want to make the room as cold as possible so winter is the best time to utilize this bed bug killing protocol. Ozone does not break down into oxygen at near freezing temps (turns back into o2 at room temps).  

I've personally killed 100% of bed bugs in an infested apartment with this protocol.  I've tried shorter run times, one day, two days, etc. but found over time seven days is best mostly because of the life cycle of the bed bug eggs.   


Ridding a place of bed-bugs isn't easy.  Using poison isn't a good option for humans or pets.  Heat is a proven option but very costly. Ozone can be an efficient way of dealing with bed bugs if done correctly.

@Jane, you can kill bed bugs over a longer period of time with 6-10 ppm if you sprinkle DE around the bed. The ozone will chase the bed bugs away and over the DE, killing them over time.

@ Susan, If you seal the room, then yes. You have to seal the vents and doors with duct tape and tarps. You need to apply DE around the bed and let the ozone generator run on the cycle (cool-tec) to create high ozone concentrations. If you allow the typical ozone generator to run, after a few minutes the plates become so hot they’re not producing much ozone (and a lot of Nox). Our ozone machines are unique in that they solve this issue.

If one can’t get 1800 ppm what ozone machine did you use to do this seven day process?

(We live in a single room. Is it possible to treat it in the manner you describe while living in it?)…is the machine on a timer for the prescribed on and off intervals??
