Chemical Warfare for Bush Snails

[kc6847]

Found them munching on my miniatures and I’ve had enough. I’ve been religiously tracking them down nightly and I still can’t get rid of them from my humidity domes.

Treatments I’m considering:
- slug-fest metaldehyde, probably my most likely option but price is hefty and not sure about the efficacy since most of them hide away from contact
- measurol (if I can even find it here in the US)

Treatments I’m not considering:
- caffeine, tried it and it did nothing, literally saw a snail eating a dendrobium bud I sprayed the night after first application, also messy to work with due to pill fillers, possible phyotoxicity especially with miniatures and in the concentration it reportedly works at according to the paper done on bush snails vs caffeine
- solid snail bait, too limited reports of efficacy for bush snails
- copper wire, likely not efficient on miniatures

Please let me know if anything else has worked for you guys.

I have not found a liquid metaldehyde product that is meant to be diluted and sprayed; most are pellets. However, Deadline Force II is a gel that contains “a powerful attractant”, so maybe that’s your best bet.

I use a pelleted snail bait outdoors when snails and slugs are a problem. You just put it down dry and moisten it with a spray bottle of plain water. For the next few days, I find dead snails and slugs underneath the plants. My Hosta's and young day lilies thank me for it. I might only have a few snails compared to slugs, but nevertheless, I find them dead as well. I only have to re-treat when I find damage building up again. I think it woks great. Good luck.
I don't have them inside.
