bad snail infestation

[Nancy T]

I found bush snail damage on root tips and 1 bud on 2 plants purchased in September 2023. Today,
I treated these 2 plants and 4 others sharing the same tray. I followed the above recommendations suggested by Leafmite and Estacion seca. So, my questions is--if I no longer see any snail damage, do I repeat the process in 2 weeks?

Welcome Nancy T.

I don't know the correct answer to that. I would treat a second time because no treatments are 100% effective, and a few might have survived.

I’m also currently battling bush snails! They ate large chunks of my mounted mini orchids, and I took the whole arrangement apart, cleaned the water catch bins, and sprayed with 1 tbsp espresso in 1 liter. It’s been a month and I haven’t seen any sign of them. I als have noticed snails in some new acquisitions, one Lycaste in particular that has multiple tiny snails every morning I looked, and soaking in 1:3 espresso seems to have finally suppressed them.
