You can also use Diatomaceous Earth. Same concept, it's extremely sharp and jagged little flakes that shred through them. It also dries them out at the same time.
It tastes nothing like Chex Mix. Trust me. More like salt with maybe a little dirt mixed in. You can get food-grade D.E.
It's also a natural flea treatment if you can't use chemical treatment for whatever reason. Does the same thing as to the snails. Shreds the exoskeleton and dries them out
Why didn't you just share the image page itself rather than the website page that the image is initially on? That way, I can view this image on Lemmy without having to go to that other site.
Alternatively you can also use aluminium. Snails have a natural allergy to aluminium due to a reaction happening between the metal and their slime. Therefore they will avoid aluminium at all cost.
