I guess it can't be the answer to your problem, but ants can be a
nuisance. I've got a bit of an invasion in the greenhouse at the
moment, and sometimes they take to sipping nectar from the edges of
the VFT traps. Every now and then, they trigger a trap, but often
manage to escape between gaps in the 'teeth', hence lots of closed
traps.
Other than that, having children gain access to the traps often
results in most of them being closed, with none of the children being
trapped (unfortunately).
