How do I treat "scale" on an office plant?
I can take it into the bathroom or outside to spray it if necessary, but I cannot use anything that smells strongly or would off-gas. I'd like to avoid anything that "looks" obvious as I don't really want people to know my plants have bugs.
The plant is some sort of fern. It was labeled as "Fern" or maybe "tropical plant" when I bought it. I believe it may be a Kangaroo Fern but I'm not 100% sure.
I have been wiping the leaves to manually remove the bugs but it seems this is not enough and each Monday I come back to see more "babies" on the plant. The little guys are really hard to wipe off without damaging the leaves.
