Slugs/bugs eating my Ludisia?

[NKOrchid]

I trust what you write and I know wikipedia is far from always right, but here's what it says (which is where I got my information from):

Diatomite is used as an insecticide, due to its abrasive and physico-sorptive properties.[10] The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat slugs. However, since slugs inhabit humid environments, efficacy is very low. It is sometimes mixed with an attractant or other additives to increase its effectiveness. The shape of the diatoms contained in a deposit has not been proven to affect their functionality when it comes to the absorption of liquids; however, certain applications, such as that for slugs and snails, do work best when a particular shaped diatom is used.

As far as I understand (my native language isn't English) that's not the same as what you're saying. However, what you say sounds way cooler and more effective!
