I can get the soap stuff tomorrow, as I have to go in to the OKC area then . . .Does Diatomaceous Earth have any success with spider mites, do you know?
No. DE is for larger bugs and creepy-crawly things.

‘Think of DE as microscopic pieces of jagged, broken glass and you’ll understand how it works better,’ says Bob Gilbert of Blue Sky Pest Control. ‘With this in mind, always be careful when using DE as breathing it can be irritating, and potentially dangerous, to the applicator’s lungs.’ It’s a good idea to wear protective glasses and a dust mask.
