Will Ozone Kill Insects?

There are those who boast that ozone will kill insects.  This is partially true and partially false.  To be clear, ozone is not a great pesticide concept unless applied at very high saturation levels.  Nonetheless, there are plenty of field reports of dead cockroaches and spiders after a strong ozone treatment.

As evidence of the ability of ozone, many grain transfer and storage operations that inject high levels of ozone to grain bins to kill off insects and their larvae.

However, these are contained areas and the ozone generators are quite large.

So, there is no question that high levels of ozone will kill and control insects in a variety of industrial applications.  The question is how this concept transfers to the everyday application of households, offices, or workplace.  These are not industrial applications and not specifically engineered solutions.  Rather, non-commercial applications are roughly applied and the success is mixed results.

The claim of killing bedbugs is a very high claim.  Bedbugs are insidious and persistent threats that the best solutions struggle to eliminate.  Heat and chemical treatments are not perfect solutions either.  Typical treatments need followup evaluation and secondary treatments to finally solve the bedbug issue.

Other insects are not as resistant to treatments. And, there are examples of insect kill during typical ozone treatment, but the results vary and are generally incomplete.

To improve results, a deep and thorough cleaning of the facility that removes the incentive and opportunity that attracts insects with food and habitat opportunities.  Afterward, an ozone treatment will likely have a greater ability to impact insects, odors, and environmental threats.  However, avoid the chemical-type insecticides and look for the essential oil insect control products now on the market.
