100 yrs ago (feels like), I lived in a hippie household in Glebe Sydney, right by the water. We had a huuge problem with rats and all sorts of vermin. All the "floaties" (dead animals etc) that choked the waterways attracted them. Rats the size of cats, the size of dogs. They'd eat through heavy storerooms doors at night, and small 22 rifles would just annoy them. So, we made up a HV HE trapdoor. It was mounted high up and when the rat walked to the center, they were hit with a vh energy pulse. We used various grids / cloth covered plates. The trap door opened and it'd fall into a 44 gal drum of water, making sure it drowned if not dead. For the first few weeks, we filled the drum each night !! A "one off" approach was pointless. They bred faster than we'd be able to kill them. Soon after, Sydney had a massive clean-up of the waterways and life went back to normal. Maybe a similar system would be better. Doesn't need to be HV electric, but something that doesn't require resetting, and "dumps" the body. |

ok, that's a bit severe :-) and environmentally unfriendly What I was alluding to was - IF you have a greater # than just 1 or 2 pests, doing them 1 at a time then going back every day or 2 may be a losing battle. A simple setup we started with was an old car battery, old style ignition coil and a trigger device. If the vermin is too big though, the coil will only stun them, is why we needed a 2nd "process". |

Large sheet of Veroboard with tracks paralleled, suitably spaced for no arc over and connected to ground and the HV probe of a tube / vac variable HV tester. Put corn on another board so the rat walks across the charged Verobaord to get to it. The Veroboard board is hinged on a balance spring so the dead rat drops into a container, works well, and if you have a power point indoors where the HV tester can be left safely and locked ON you can run car ignition cable to the trap. Has dispatched dozens of the blighters...As someone said a car electronic ignition system with a simple circuit to keep firing the coil will also work, and from a car battery... The less "feeling" would just let the rat drop into the container and die without killing it, not sure if the squeaking would deter others though :( |

OP I would use a magnet and reed switch. Vibration sensor may not work as the soft squishy rat will dampen the trap's closing, and its weight is on the trap too. It rain outdoors so anything else I think will fail from dirt and water. There's several electric mouse/rat trap videos on youtube. Once the HV is on they jump up off the electrodes and run/bounce away, unless you have a cage cover or something complicated to navigate which keeps them there long enough. |
