According to the views delivered from my contacts at EPA, nearly any substance that is used to kill, repel, or otherwise mitigate a pest may be considered to be a pesticide. This is particularly the case if the chemical is prepared elsewhere but is then transported and applied at another location. So, carbon dioxide (in bottled or frozen form) is definitely considered to be a pesticide if used for mitigating a pest. If it is used to put fizz in your soda, it is not a pesticide. In contrast, carbon monoxide generated as a product of combustion, even if used to mitigate a pest, is not considered a pesticide, as it is generated on site. According to this logic, argon, if used for the purposes of fumigation, would be a pesticide. I anticipate that EPA would require that the bottle of argon be labeled with a pesticide label and carry an EPA registration number.
Don’t ask me to support the logic of this distinction. I’m just a messenger who has had too many conversations on this matter with folks from EPA and from several state agencies. -Rich Richard J.

Argon is not a pesticide. You may see as analog to heat, cold, gama rays... They are not pesticide, but kill bugs using different aproaches.

We have a large open-air taxidermy exhibit that has problems despite using preventative measures, so we unfortunately have to resort to fumigation on occasion. We are looking into changing our current fumigant for various reasons, so I was curious if anyone had any non-residual and non-oil-based aerosolized fumigation recommendations.
