I just discovered the sad news that I had fungus gnat larvae in my pot with some cactus seedlings and they ate my cacti! I thought it was weird the other day when I noticed a seedling missing from the pot! I don’t want to give up on growing a cactus in the future but I want to be prepared for the possibility of getting the pest again. Any tips to prevent them?
