12 volt killing question

I have seen songbirds killed by electric fence. Granted it wasn't a 12 volt, but voltage doesn't kill, amperage does. I've seen 12 volt fencers give a pretty good zap.........

"Electric fences" that I'm aware of are in the neighborhood of 50,000 volts and very low current.

Thats a rather substantial difference from 12 vdc.

Due to there size I wouldn't dought that a small bird could be done in by an electric fence . . . ._If_ they were so unfortunate as to bridge the Hot to ground.

Out at the road I have seen hundreds (over the years) of birds sitting on ONE leg of the 7200vac utility transmission line. . . .

Now if a very large wing spanned bird were to touch both of those 7200v lines at ounce . . . .of course -- ZAP.

Enlighten me if I'm wrong but I have never heard of a fence that uses 12 vac or dc only . . .?

My thought is to take a 12"X12" square of 1/4 mesh and nail it to a frame made of 1"X1"s. I will then build a upside down L shape out of 1"X1"s. Hook neg to the mesh and run the positive wire up the L and have it hang 2" off the mesh with peanut butter on the end. Hopeing rats or mouse will stand on mesh and reach for peanutbutter and complete the curcuit.

I do have a old bug zapper out in the barn it the tubes busted out of it. Maybe I will look it over tomorrow.

Jon, interesting idea.

12vdc wont zap them
But 120vac will
Ever see the old hot dog *cooker* where you plug the 'dog' into those little probes on the unit.
then you plug it in and the ole dog sizzles.
You have just electrocuted a 'dog'.

LOL . . . . . on the down side if Mr Moussie isn't thrown back by the shock, and he remains in contact with the wires . . . .I'm wondering iffin *fried mouse* might get a wee bit stinky. . . .??

If you try your idea (with 120vac) be damned carefull . . . . . . .and keep us posted on the results . . . .

Yes, they make 12 volt fencers. The fancy ones have a solar charger.

I went into full attack last night and started setting every trap I had laying around. Went down into the basement to put out glue traps and decided to crawl behind the furnace. There is a 6" pipe that goes straight to the outside under our deck and it is not screened or louvered in any way. I wonder why I have rodents. Anyways there is steel mesh over the inside of the pipe now.

Count since last night is 4 (3 normal mice and 1 frankin-mouse (I refuse to admit I have rats in the house)).

Thanks for all the suggestions.

Hook wires to your 12V battery and touch them to your tongue. Assess the results. (It won't hurt.)

Another trick is to save the bottom caps off of soda bottles. Fill them up with rat/mouse poison pellets and put them in nooks and cranies, behind doors, in cabinets, on shelves, etc. They prefer to follow walls.

Trying to stay away from poison because of pets (cat and dog) but on second thought they both are kind of worthless so maybe it won't be to big of a loss.

Jon

tinknal . . .yes I'm aware of those solar pannel fence chargers. Thats the only way to go(solar power)
Suggest you look again at those. That 12vdc powers a circuit that makes the 50,000+ or what ever, volts. They do not put 12vdc onto the fence *wire* . . . .but Very high voltage.

I'm not in favor of the poison either because way back when I used it and the damned things crawled off to some inexcessable area (in a wall ?? ) then they putrified and stunk badly for a long time. . . . . .I wouldn't want to go through that again on a bet.

As of this morning I've got two mousies that have miserably failed their swimming test . . . . . aka CF's idea . . . . it works.

And yes they used to make direct current fencers .. I have a neighboring family who lost a son back in the fifties from a dc fencer , they are no longer made for obvious reasons , but occasionally you will find them at farm auctions even now ... I have an old one that I got that way , in a box of stuff ...

Jimmi, I'm not saying that they will kill mice, I'm just saying that, having experienced the shocking power from them, I'd put them in the same class as a 120 volt fencer.

Hook wires to a 9 volt smoke detector battery, touch them to your tongue. Assess the results.


Now put that same 9 volt battery in a Taser, touch to your tongue..............I'm sure you get my point.............

A 12 volt deep cycle has plenty of current to kill even a human the voltage is basicly unimportant .
look at voltage like a river the more volts the wider and deeper the river
a none moving river isnt very deadly . neither is a million volts at a nanoamp.
Now look at the amperage , this is how fast that voltage river is flowing.
the more amps the deadlier.
I amp can kill a human if the timings right.
fence charges use a transformer and capaictor to store high voltage and discharge it at very low amperage ,these milisecond dischrages are rate in jewles yet another nice little eletrical term.
the victor eletric trap uses a modified photoflash unit that charges up from the 1.5volt batteries just like your camera flash does . the power is stored in capacitors and dischraged when it mouse completes the circuitthe mouse is being hit instantly with around 600volts at 5 amps ( just a guess depending on the capcitors used ) or somewhere around 500 jewles. Keep in mind to shock a heart attack victim they use under 300 jewles in most cases , if the same is used on a healthy patiant it can stop the heart.
I wouldnt recommend wetting your hands and grabbing the posts on a car battery

Yes higher dc voltages are deadly.
When I install a PV system with the pannels in series, that 100+ dc voltage must be handled VERY carefully.
A high voltage dc fence is really a bad idea.
I wonder how many critters were put down before they realized there mistake.

Just for kicks I'd like to find a Victor electric trap.

But untill then I'll keep trying to give Mr&Mrs mousie swimming lessions.

No batteries needed . . . . . . . . . . . . .
