Yes certainly, there is bad karma for killing any living beings
that has consciousness. They suffer pain, and all animals are
naturally fearful of death (tan1 sheng1 pa4 si3). When you try to
kill harm them, they run away for their lives. In Buddhism, loving
kindness and compassion are very important qualities. Therefore a
true Buddhist avoid killing even the smallest animals.
But there are wiser ways to get rid of pests.
I posted in the forum more than one year ago:
Hello, my master Ven. Shen Kai offered a solution to Ants and
#^@$roaches. He also mentioned about mosquitoes (but I can't
remember well for that one). I will summarise a few points
below.
Ants - put some Mei2 You2 near their home, they dislike the Mei2
You2 and will definitely move away from their home to somewhere
else. To give the ants a sense of direction where to go you may put
some food nearby, and they will go and live there. But don't put
the food too far as it may be difficult for them to travel that far
distance.
#^@$roach - get some empty Wu3 Jia1 Pi2 Jiu3 (a type of Chinese
traditional beer?). #^@$roaches love to have a beer and will all go
inside. Then you can throw the cans into a dirty place i.e trash
can and let them live in their paradise. I don't know about other
beers, you all could experiment yourself.
Mosquitoes - I can remember only he mentioend two ways - burning
that mosquito 'incense', or using some kind of electronic device
that could make them sterilised and not be able to reproduce
babies.
So we do not necessarily need to kill them to get rid of the pests.
Wisdom will be of good use.
My Master taught - to develope Great Compassion one must start
by not harming, and protecting animals no matter how tiny they
are.
Even though these animals may be tiny - if you can kill small
animals, one day you might kill bigger animals, then killing humans
no longer seem a difficult task to do.
Namelessness:
I was taught that if we truly accomplish non-duality, we would
be in one with everything. Certainly, we would not be bothered by
anything because everything is us and therefore we won't kill
ourselves.
But it is hard to get there for ourselves, not to mention our
family members. So far what I can do now is to communicate with
those animals and tell them not to bother my family. Because my
family still kill them without mercy once they appear in the house.
I just warn those animals in my mind that if they ever come into
the house again, they would be terminated.
So far it works very well for %^@#roaches. But we can still find
one or two %^@#roaches crawling in the house per year, especially
young ones. Perhaps they didnt hear me or warned by their parents.
