Look what I found...snail on Vanda

[cirillonb]

while watering I found this tiny snail crawling on the Vanda packong's label. The plant was purchased in mid July and repotted into EpiWeb and PrimeAgra in late July. The previous medium was bark which was fair. The original pot was buried in the plastic basket in which I received the plant. There were a lot of little clover-like plants on the plant and copious amount of clover roots. I cleaned out as best I could. The plant is doing great. I even see a flower spike. Naturally I crushed the snail after taking its picture but I am at a loss how to treat the plant. My critter rule is if you see one expect many. Any suggestions. I am not above using chemicals.
