Is the DE you're recommending the same DE that is used in pool filters? I though the insecticidal DE was a finer grade than pool DE. The finer grade is actually smaller and have sharper edges that cut the insects walking on it, opening its guts and killing the insects. The normal Pool grade DE is too large to do this.

Actually, it does work as an insecticide. My parents used to fight about it--Mom would steal some of Dad's DE to kill the ants in her gardens--and he would squawk that he needed it for the DE filter. Very entertaining for us and our wives!

It may simply not be as effective as the garden grade, but is definitely effective.
