I agree that it's very difficult to uphold the 5 precepts. I
have similar occurence in my bathroom. Just to share on experience,
water does drown these little living creatures, and by taking a
shower, I'll be killing them. Most of the time, i'l try my best to
evacuate them to the nearest grass patch, using all sorts of
"tools" like tissue papers, papers etc. Of course, by doing so, I
could be committing another form of killing by introducing them to
their natural predators like frogs, spiders. My perception is that
in this way, they will not die "unaturally". For those that are
killed unintentionally or intentionally, I would suggest dedication
of merits to them, so that they will reborn in a higher realm
because of you. There's no way that a human will not kill, because
there are many big and small creatures around us, that we breathed
in, stepped on daily. I'm sorry that I do not have a concrete
solution to your problem, but I'm sure other seniors in this forum
will be able to advice constructively on your difficulty.
