DE or Diatomaceous earth
DE overkill or not? OK you know how I am about Do It Yourself, right? Well this is a great example of over application. It looks like it snowed in Phoenix, Arizona. The weird thing about this, I’ve seen worse inside a bedroom. The bad thing is you can damage your nose and lungs breathing this stuff. It works really well on bugs/pests by dehydrating their exoskeleton and they bleed to death or absorb chemical faster.
First off only the food grade product works on bugs, not the pool stuff – it is cut differently. The fine powder absorbs lipids from the waxy outer layer of insects’ exoskeletons, causing them to dehydrate. Insects die as a result of the water pressure deficiency, and considered to be relatively low-risk.
