No Kmarch, I haven't seen any other evidence of slugs or snails. No slimy trails. Besides, how would they get in the house? The plant was not outside this summer, but it was sitting next to another Phal with a really long bloom spike (plant had finished blooming) that I just cut back the other day. Could it have gotten poked when I was watering and moving things around...hhmmm. I'm still going to keep an eye on this spot and make sure it doesn't spread. Maybe it's silly,but I'd rather be safe than sorry. Thanks for your suggestions
