co2 death chamber

[Vernmented]

I just bought my first live live trap and I need a way to humanely dispose of the little buddies. My neighbor is starting to complain about possums even though I don't have much fruit at the moment. I live in a deed restricted neighborhood and I am trying to keep my neighbors happy. I can't use my guns due to the close proximity to the neighbors. Right now I am thinking about making a co2 gas chamber. I would like to put them down as humanely as possible. Does anyone have experience with these? Any tips? Something like these.

That looks like something out of nazi germany.  Use a bb gun or a 22 with powderless super calibri shells.  They don't make any noise.  If you were a possum on death row how would you want to go out?  Gas chamber or firing squad?

The little .22 CB shorts they sell at Walmart are actually quieter than my pellet gun. I wouldn't hesitate to use it to dispatch a varmint even in a densely packed neighborhood.

We have been using a rabbit sized have a heart trap baited with a scoop of peanut butter.  Once a squirrel is caught, it is relocated. 

What about a motion activated water sprayer?

What are you trying to get rid of? Possums? They are generally harmless. It's the rats and the squirrels that do the most damage.

co2 causes severe respiratory distress (In severe hypercapnia (generally PaCO2 greater than 10 kPa or 75 mmHg), symptomatology progresses to disorientation, panic, hyperventilation, convulsions, unconsciousness, and eventually death.).

Nitrogen or helium would be much kinder if you need to pursue this method (https://en.m.wikipedia.org/wiki/Inert_gas_asphyxiation).

This publication has a discussion of all kinds of euthanasia... http://icwdm.org/PDF's/AVMA2007report.pdf. It notes the best method depends on the animal. And this one details the co2 method.....
http://icwdm.org/wildlife/euthanasia/Carbondioxide.aspx
A whack on the head is noted as a good method if you can execute it effectively. It is also listed as not recomended.... go figure!

Co2 seems pretty cruel.  Why don't you just take them out someplace and turn them loose?  I have a favorite spot in a brushy area a few blocks away where I take all the mice I catch in my greenhouse.

I would not kill possums unless the situation is really bad. They are one of the few marsupials in America. Turn them loose a few miles away. Tarp in the trunk of your car due to possibly pissing or shitting. With problem rats, mice, squirrels you drown them.

You will get bitten and scratched trying to transfer a possum into your CO2 gas chamber.

I think the idea with the chamber was to build it to accommodate the whole trap.

I'll also second the notion that I am pretty well opposed to killing possums. Those things devour ticks and besides being kind of gnarly looking don't really hurt much.

You know how you get crazy panicky when you try and hold your breath as long as you can? Rising CO2 levels are a big part of the sensation of needing to take a breath, and killing an animal with CO2 is a pretty inhumane gas choice in my book.

I have not tried these methods.

The silent killer is typically considered carbon Monoxide CO (not carbon dioxide CO2).

However, it appears that purification of exhaust gas is seldom done by the do it your selfers.

If a rodent were caught in a cage, one could simply put a plastic tarp, visqueen, polyethylene plastic sheeting   etc. over the cage and supply an exhaust source under the tarp (cheaper than buying that huge device above).

Heightened CO2 induces panic attacks in people, and similar symptoms in animals. I agree, let the opossums live, and do not kill with CO2.

I've been dealing with a squirrel problem. Have come close to going to war with them, but have instead been trying to appease them with other treats. Moved my bird feeders away from my fruit trees, and fill them with a good blend that birds and squirrels really seem to like. As long as they are stocked, not much fruit loss due to squirrels. If they get empty, the squirrels go after more fruit. Have also tied some Irish Spring soap bars to a couple of trees, along with pandan leaves, which they do not like. If I had a few cats, doubt there would be much of a problem.

You won't  be able to choose between critters and may end up killing a pet


I was having problems with possums and coons so I got  the have a heart and relocated 10 coons and 11 possums

Then I found out transporting a live coon is against the law

Then I got a golden retriever that takes a dump like a camel and no more visitors

Get a dog they work great

Yeah, cats would most likely investigate that...then you may be dealing with animal control and/or the men who drive around with lights on top of their cars.

Also, when winter comes again there is an increased risk of deaths in homes from combustion of Vehicles in garages, heaters (not ventilated outside the home), gas grills used in garages and also not ventilated outside. Unfortunately we humans do not realize we are dying and CO is too tightly bound to hemoglobin to allow O2 to enter the blood stream and a  sleeping death often occurs from ex. running a car in a garage.

50 seconds into the youtube video   https://www.youtube.com/watch?v=KmgIqVwytwA
   or    https://www.youtube.com/watch?v=FRn_sONIrRI

So now you know a answer concerning animal cruelity if using combustion from gas engines etc. === yes or no. Many human animals have been pulled out and revived from a garage with vehicle running and they usually say no except for a slight headache occasionally and were unaware of the gas usually.

I guess I will just relocate them for now. I like having animals in the yard as long as they aren't eating lots of fruit. I don't mind sharing one or two. I have dogs on all sides of me. Every neighbor. The neighbor that said something was complaining about possums in their yard and the dog wants to play with it and eat it's poo. I like the idea of running a car exhaust pipe to a chamber if it comes down to it.

Is it definitely illegal to relocate raccoons in Florida? The paper I was reading mentioned the release site needed to be 40 acres and you needed to have written permission from the owner. What about possums?

What are you trying to get rid of? Possums? They are generally harmless. It's the rats and the squirrels that do the most damage.

The neighbors. Unfortunately they keep declining my invitation to get in the chamber.

I would trap the animal and put the whole cage in a vessel so I would be able to release non targets.

CO2 for killin animals is not humane.

in biomedical research involving animals, this is consider one of the less humane methods of euthanizing animals.

also, babies of some small mammals are able to tolerate long periods of CO2 without dying. CO2 euthanasia is disallowed for baby mice in biomedical research.

[DocFruitFly]

Nature's method for killing prey usually involves biting the neck to crush the esophagus or sever the jugular. You could try that.

But in Florida it is illegal to relocate "nuisance wildlife" without jumping through a bunch of hoops and animal control won't do it either. You can pay a pest removal company to relocate it for you for about $80. I've always heard that CO2 was the preferred method, but apparently that's not the case. Helium would work and make them have funny voices as a bonus, but it's pretty expensive.

Guess I'll just stick with the .22

Nitrogen dioxide aka hippy crack would be way kinder, they would go out in a head buzz opposed to co2 which triggers the body's 'I'm choking to death, I need air' response. Nitrous oxide you just get light headed then pass out as it replaces the oxygen you breath in and doesn't give any type of choking response.

Just make sure they sit down when they take it or they can fall on their face and break their teeth.    yeah I have seen a few grateful dead concerts when i was younger.

[Yorgos]

Why not a bucket of water that the trap fits into?  This takes care of squirrels/rates/mice in a very few seconds. ThisCO2 contraption seems way too complicated. (and relocating your trapped rodents elsewhere shows zero consideration of the people in that vicinity).

lmao, saw that once at a Dead show; guy fell straight on his face. Walking through the crowd of campers outside the Omni hours later; same guy, bloody face, going at another balloon. Hilarious. Not a good learner.

I can see it now, lure all the pesky critters down to your hippy animal concert and then do your dirty work.

Firing squad assuming that death was instantly.

Will a BB gun and/or powderless 22 shell kill a possum instantly?

[spaugh]

If the animal is already trapped then it should be easy to make a clean kill.  Obviously you need a decent power bb/pellet gun.  Powderless 22 to the head will definitely put out a possum quickly.  Just don't expect it to fall over and drop dead like in the movies.
