The most common method of killing laboratory rodents is exposure to carbon dioxide (CO 2), but recent studies have shown that rodents find this gas aversive.Exposure to 30% CO 2 is necessary to induce unconsciousness (Chapin and Edgar, 1963), but rats are unwilling to tolerate concentrations as low as 15% (e.g. I've euthanized rats and mice using a homemade CO2 chamber in the past for pre-killing food for snakes.

Niel and Weary, 2007). It is essentially the same as suffocating it. They are ideal for the herp enthusiast that breeds their own prey to save money but do not like the idea of feeding live. The Cheetah machine kills burrowing rodents by capturing exhaust gases produced by a gasoline engine.

This seems relatively simple. Aversion tests in rats experiencing gradually increasing concentrations of CO 2 show that rats will leave the test chamber despite the presence of an attractive food reward when the concentration of CO 2 reaches an average of 11.1% to 18.4%. In March, New York City began filling rat burrows with dry ice in order to kill rats. Albino rats generally prefer to stay in the dark, so the researchers wanted to determine which bothered the animals the most — bright light or a noxious atmosphere. Co2 chambers are very easy to make and are extremely useful if you have multiple snakes or lizards that feed on rodents. If done slowly, the rats/mice don't act nervous in the slightest. 17 The authors of the cited study 17 also observed that the CO 2 concentration at the time the rats left the chamber varied with flow rate. They groom themselves, each other, sniff around, then get tired as they slowly get less oxygen, and eventually pass out. Plenty of people use CO2 with great success, do some searching around and you'll find what you need if that's the avenue you pursue. 1. Dry ice, vinegar+baking soda, or paintball-style canisters with regulators can all be used to pump CO2 into a kill box. A possible solution I can imagine to kill them, is to inject carbon dioxide gas into the wall cavities to asphyxiate the mice. I've got a CO2 .177 air rifle you can borrow. Co2 Chamber. When combined in the proper amounts these common household ingredients produce C02 levels that will first anesthetize then kill the rodent. Targeting rats and mice, the weatherproof trap kills rodents repeatedly without toxins or electricity, automatically resetting itself after each CO2-powered shot so you don’t have to. Outside of a container, the dry ice turns to gaseous carbon dioxide, suffocating the rodents. Simply mount it, sit back, and then toss the remains (or, if installed outdoors, let scavengers do that for you.) I just need a bottle of CO2 with a pressure reduction valve that releases the gas at 1-2 psi. if you really want to gas the rat use Carbon Dioxide (CO2). And research done on human volunteers has shown that they experience “discomfort that intensifies to overt pain” when inhaling CO2 at 30 – 50%, concentrations typically used for gassing animals. Introduction. Eliminate squirrels, gophers, prairie dogs. Shoot rats with the cheapest .22 air rifle you can get. Exterminating Rats With Deadly Automobile Exhaust Gas (Jul, 1931) Exterminating Rats With Deadly Automobile Exhaust Gas “IF THE fumes from an automobile exhaust can kill humans, they should have the same effect on rats,” said the head of the Department of Health of Highland Park, Michigan.
