The bottom of the other plant didn't seem like it was covered in anything- the white balls were a little firm and didn't dissolve in water. When I got home from work this morning I moved the pot and it seemed like there were just as many, if not more white balls with new little orange ones popping up. I can't really tell if there's a smell from them- there's so many plants that the entire room has a soil-y scent.
When I read the Amazon reviews for the mosquito dunk/bits it said they worked on fungus gnats too. One goes into the water and the other you sprinkle into the soil. I also bought a 100 pack of the sticky squares and they work really well! A review said to mix the dunk and water them with it- do you think it's hurting the plants to use it like that? I've only watered them with it twice since I've purchased it.
Here are the pictures for reference-
