Some kind of catepillar is munching on the edges of my Nep leaves and pitchers. They are about an inch or two, thin, covered with lots of fine white 1/2 inch "fur". Also, something is eating holes inside the leaves of new shoots and causing them to sort of grow deformed. I was wondering what insecticide is best and if I have to use one that requires a hose and bottle to spray or can I just mix it in a spray bottle and spritz it on manually. I'd be afraid of using my hard alkaline hose water on my Neps. The infestation isn't bad but its making for a few ugly leaves on nice big plants. Thanks.
