If you want them to hatch, leave them where they are. If you don't, take them off the tank and discard them.
I just woke up this morning to find out that my gold inca snail, Unsub, is actually a female and gave me the gift of a lovely column of eggs. I removed them once she was done and had moved away from them by her infamous random releasing of the wall and dropping down to the sand. I used a paper towel and scraped them off with my fingers under the paper towel. I discovered that when pressure is applied to them, they instantly burst into little piles of mush. After that disgusting moment, I managed to scrape the rest of them as a solid column and throw them in the trash, which I'm about to take out. If it helps with the rest of the posters to explain my moment of disgust, they were fresh eggs that became wet mush for me. I hope I never have to remove them again.
