Ok I know i will get flogged for this 'unsafe' method of killing my backyard varmints. but please just go with it. I already tried spring traps, buckets, cages, rat poison. what i kind of learned is they are not interested in my food bait since they have alternate food source ,palm fruits, etc. Every day, as I am sitting in my living room looking out the sliding door, i see them running across the cement patio right in front of sliding door. i am thinking if i can lay down an electrician grid on the cement which could instantly kill them as they run across it. the jolt would have to instantly kill them or paralyze them the moment they come in contact. i dont want them escaping the jolt. i am just not sure how they will react since rat/mice are very careful on what they touch. I will be sitting there with a on/off switch in my hand monitoring the trap to pick up the dead rat for burial. no bait is involved , i already know their jogging path; just need to lay a live grid. any ideas to share on this please. i dont have pets or small kids and the ground is dry. my background; i am a technician with above average diy skills electrically speaking; let me know if this subject is out of scope with this forum so I don't waste your time. thanks.
