I have a fruit gnat problem(so to speak) in my terrarium. My plants seem to be fine with it though. They are all getting lots to eat. My pitcher plants seem to be eating the most then my sundews. I can't tell about my nepenthese and cobra lilly. My venus flytraps are are getting the smallest amount. They aocasionally get the grown gnats that escape the sundews. Is this okay that my plants are getting this much food. I have had the infestation for about a week. Do I need to get rid of the gnats?
