I was just feeding and watering my neps when I was checking one of them. I noticed that one of my newer neps has not formed any new pitchers (one was forming, but has withered away). While looking at it, I saw some "gnats" fly out of the soil and one of those "pill/armodillo (sp?) bugs". The gnats are not "fruit flies", but something about their size. Any advice on how to get rid of them? Are they the culprits? Any advice would be greatly appreciated.
