BTW, Goldslinger, I have tried worm pieces too,a nd I think it's not bacteria that kills the trap-I think it's just too rich. Is that what you mean by "damaged", Joseph, with the slugs?
I have black ants cause the same thing FlyTrapNewbie mentioned. I did not think they were carpenter, but they may have been young ones. Ants have some potent chemicals in them-has anyone wver watched the video "Death Trap" where the ant bites the D. rotundifolia leaf and it kills the leaf(they show it under time lapse photography)?
But, like Joseph said, there is no sign saying"you must be this big to enter trap", so traps may die, but the plant still thrives.
I guess, if I were looking for the optimum insect, it would be about a third of the length of the trap in size.
Randall, have you tried feeding the traps directly instead of leting Nature take it's course?
Cheers,
Joe
