I read with interest the study link elsewhere in the forums that sites CimeXa superior to DE.

First off, I don't claim to be knowledgeable.
However, I did read the article. It is hard not to question the study based on a couple observations.
1) The first lab study compared CimeXa to Temprid SC which I am assuming is not DE
2) The second lab study compared CimeXA to DE and concluded: "Almost all of the bugs (97.5 percent) died within 24 hours of walking over silica gel dusted carpet, while only 10 percent succumbed by then to diatomaceous earth " However, it did not disclose if the DE simply took
longer to do its job. It shows a graph of the kill rate over time for ciMexa, but does not show one for DE. When I see omissions like that I always ask myself what went into the decision to show one and not the other.
3) The third test (Field study) compared CimeXa being installed as a dust vs in a water solution
Experts, is there really a practical difference in results?
