I agree totally with Lou. Has Bernice tried pheromone traps and/or glueboards? For some unknown reason, both sexes are regularly caught on standard glueboards.Tom Parker

Being a dessicant dust utilizing amorphous silica, it can be an inhalant issue; it also contains a small percentage of crystalline silica which can lead to silicosis.

I’m strongly in favor of a deep clean followed by the application of large amounts of diatomaceous earth. Some DE would be applied to cracks and crevices around platforms and below cases, but I’d concentrate large amounts into interstitial spaces behind walls, and above the ceiling tiles on the drop ceiling. I think I have a safe plan for the DE that would go in the lower interstitial spaces, but I have concerns about its use near the ceiling air vents since DE can be a respiratory irritant. Has anyone dealt with this problem? Is there a way to protect or consolidate the DE so it does not enter the HVAC system? Is there a better solution for the areas near the air vents? I’d love to hear opinions from this always helpful group.
