I found this the other day and intend to try it and report back. Simple enough and best of all no chemicals, some people even eat bentonite. Apparently even works on slugs in the garden!
“(Bentonite clay) powders have no additives. Under a microscope, powdered Diatomaceous earth is made of a whole lot of broken diatoms.
To an insect, these are extremely sharp, hard edges that resemble a minefield of broken glass, cutting and abrading away their waxy layered exoskeleton.
Insects get severely injured in their joints and bodies. They desiccate and they die. They can’t build up immunity because it is a mechanical mode of action.
Diatomaceous earth powder when blended into potting mixes at two to three per cent by volume will control insects. It can also be applied topically on the ground, applied to foliage as a dust with a puff bottle or hand-cranked blower, or mixed as a wettable powder to spray onto the top and underside of leaves.”
(Not sure that this is safe for all carnivorous plants)
