Has anyone tried the poison gas method for rats in their tunnels?

That is the next stage I'd like to try before bait poison.

We've been doing great cleaning up the yard, making food inaccessible.Haven't seen a rat in a few days but know they're there!!

It's the Giant Rodent Gasser: https://smile.amazon.com/gp/product/B000BQLWCS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

Has anyone had any luck with this method?

I break up dry ice and drop the chunks down the holes. It's more dense than air and settles in the low spots of the burrows. It works.

What is the dry ice actually doing? I guess I don't know anything about dry ice--is it toxic to rats?

Dry ice produces CO2 as it melts.
this displaces the oxygen and in theory would make them suffocate or vacate their holes seeking oxygen.

In theory! Unless their network of tunnels is vast.

Have you had success with this method?

 

[Kasilofchrisn]

Yes in theory.
I have not tried it myself.
I bought some of the poison gas sticks but never used them.
A friend talked me Into getting a ferret and he loved eating fresh rats.
That and they were in the barn walls and I got scared of a fire from the burning sticks.
I did trap/shoot quite a few of them.

Dry Ice is solid carbon dioxide...so as the dry ice sublimes (goes from solid to gas) it will force atmospheric air out of the tunnels, because it is denser than air, it will stay in the tunnels as well.

41 grams of Dry Ice will expand to 22.414 liters...so a 5 lb block of Dry Ice would take care of a huge system of tunnels.

I've used it on Prairie Dog burrows...I've used it to dispatch predators in cage traps, works like a charm.

The heck with dry ice. I'd get one of these!!!

I like your way of thinking BBQ JOE!
I was going to suggest something like the prairie dog vacuum truck they have out west that sucks them out of their tunnels and into the truck.
But it's rats and they would still need to be dispatched.
Your idea takes care of all that at once.
