Bedbugs. I slay them by using a water spritzer filled with Rubbing Alcohol. In about 5 seconds the alcohol burns them from the inside and at the same time drowns them.
A Critical hit!
Then the pain would set in and you would start crying like a little girl.
Actually, believe it or not, I'm the real-life Renard from The World Is Not Enough. I feel no pain [most of the time]; I suffered a bump on the head when I was 3 and stopped feeling pain to a certain intensity ever since.
As much as I loathe bees, they do have a purpose on Earth other than pissing people off.....and stinging genitalia apparently. *shudders*
Wasps are very effects pest control predators. They prey on crop pests such as hornworms and caterpillars, which costs a lot in annual loss, both financially and stock wise. Without them, those pests would be free to ravish fields upon fields of crops and cause inflation to things like tobacco and tomatoes.
I feel bad about killing certain bugs. If it was a bee or spider I'd kill the fucker without remorse. But I don't think I could ever get myself to kill a ladybug or butterfly. I think that'd discrimination against bugs.
