Everyone's survival is dependent on the death of others.... even Class 6 vegetarians who don't eat anything that casts a shadow.
Expecting to be able to survive without incurring death unto other sentient beings is unrealistic, and seeing this reality as it is, we should not set unachievable expectations which will cause us unnecessary and additional suffering.
Yeah. I'm with you, it's just the principle is not to kill living things right? Well.. these are living so I felt like the precept should probably apply to them. I just want to make sure I don't have to make a late night trip to the toe-tag section at the hospital because I get stung in my sleep.
I figure if there's a humane way to deal with the issue, then that's optimal. I just don't know of any ways to easily catch these guys.
