what are the strange white bugs in orchids?

Question

My house plants became infected with a strange white fuzzy bug after an orchid that was given to me had died. The orchid also had the bug. I’m not even sure it was a bug or some kind of mold or fungus.

Answer 2

Whiteflies
Carefully spray the entire plant, top side and bottom side with a solution of liquid Ivory soap and water. Leave it for the day. After the sun goes down, repeat the process. You can use a bar of Ivory soap to cover thick stems. The next day, repeat the entire process, beginning with removing adults and spraying off the plant thoroughly, and applying soapy mixture twice.
