What ingredient is that? There may be more than one chemical used.
The DIY version of mite paper uses Benzyl benzoate, I believe, which is a miticide (https://pubchem.ncbi.nlm.nih.gov/com...enzyl-benzoate
One commercial paper (https://www.silkwormshop.com/shop_mladynobugs.html
) uses Isopropoxyphenyl methylcarbamate, which is a general insecticide.
Some flea and tick sprays contain methoprene, which prevents insects from completing their life cycle (by interfering with larval development, I think). I don't know if this is used to prepare mite paper, though. If it was, and it hung on to mites long enough to interfere with their larvae, then it would likely interfere with any FFs they interacted with -- so I'm not sure this is it.
