I was taking a nap two days ago and I accidentally grabbed one of those furry little f*ckers (read mouse) on my bed. I freaked out like a little girl and I jumped out of the bed. Then I started regretting that I don't have a cat anymore (he left and never came back). Mice can get inside your house if you leave doors open (or by other means, like faulty floor or walls). However, I never really had one get in my room until now (or at least the cat I had eventually ate all of them). I tried capturing it today, not necessarily killing it, and I failed even though he was confined to a space behind some furniture.
I went to wash my hands and when I came back he was sitting on my doorstep. I moved slowly, grabbed a broom, carefully aimed at its body with the top of the handle, and smashed him as hard as I could. It moved for one or two minutes while I was squashing it even harder until it eventually stopped. I picked it up with a dustpan, threw it away, and cleaned the blood that was left there. I don't recall killing any other animals before (I did dabble in insect murder, mosquitoes and houseflies in particular). It felt really good. I am generally against violence, but I believe that for a few moments I felt what a serial killer feels when he\she murders people. It was totally worth it.
What about you? Have you ever killed any pests? Did you enjoy it?
