I just went outside and discovered that several of my S. wrigleyana pitchers, S. flava, and S. alata pitchers had been munched.
Fortunately, I also caught the culprit red-handed and exacted revenge with a hammer. Oh, how I wish those little buggers could feel pain!
The remains are currently nourishing my N. miranda.
I'll need to check for them daily now.
Any potent pesticides you'd recommend that won't harm the plants?
Bear in mind, they're in an undrained large pot, so something that will break down eventually is preferred.
