Gas for rats

[shakey jake]

Wasn’t cymag and strichnyene banned after the 9-11 bombings as I remember using cymag and talunex and phostoxin at the same time but on different jobs,talunex and phostoxin were a lot cheaper to buy than cymag which was a lot bigger tin I used it in a cymag pump which looked like a stirrup pump I’m sure I still have one at work somewhere,w

neither were banned they both needed to be tested for a more modern label. no body would back the testingas the product would of gone up hidiously in price. they then had the license to use revoked, they could be tested and come back but i think those days are gone now

And rightly so in my mind

Rats can be too ruddy smart where Phostoxin is used.
A mate and I once had a weeks work gassing the rabbits on a big farm (phostoxin used). We would send 2 or 3 'Phozzies' down the burrow and then block off with a good sod of soil and a firmly applied welly. We got to one warren and decided a couple down every other hole then block off ... By the time we got to the third hole we discovered that the local rat population of about a million had taken over the warren and we were surrounded by them ! They were NOT going to sit at home and be gassed, they got one whiff of it, and they were off !

Why do rats cause such over-exaggeration.Farms I do see a few and they are infested .No your not farmer ,call me when the buildings wall to wall .

 

[Longstrider]

Ok ... so maybe not a million. Perhaps 999,000

The rest of them moved to my house.

I have never seen gas used for rat control and have not personally used gas for any pest control. I have corresponded with researchers that have done studies on gas vs bait for gopher control. The general consensus was that use of gases and gas bombs are less effective and more dangerous than baits. Many gases and gas bombs were tested. Of the gas products tested, methyl bromide, chloropicrin, and a nitrocellu-lose film bomb gave the highest percentages of kills. About half the gophers succumbed to gas and gas bombs. Baits were found to be more cost effective than poisons. Compared to poison baits, the cost of poison gases is excessive, even more so when labor and equipment costs are added. Cost of materials was almost negligible in bait poisoning. Success in poisoning with baits was believed to be attributed to high acceptance of baits by gophers who seem to be readily attracted. Gophers were easily lured by any poisoned bait. I expect more studies have been conducted which would yield more information. I am just guessing but would expect similar results in gas vs baits in rat control. Additionally baits for rats can be placed in bait stations. Of course there are inherent dangers of using poison baits. I have used snap trap box sets and poison bait stations around quail raising facilities with good results. Rat control is perpetual.

I'm not sure you can gas gopher holes safely. Don't they have single entry holes? In which case the gas, if it were pumped in, would come straight back at you. A couple of phostoxin tablets however with the hole blocked would surely work?
Not that I have experience of gophers of course, last free range ones I knew of were in the Isle of Wight some 30 odd years ago.

I don't know if you can get it these days but as lads, we used carbide in tin lids with a splash of water and it fetched them out a treat. For those too young to know carbide was used in bicycle lamps " back in the day!"
It was in red tins in Halfords!

There are a lot of differences and similarities in rat holes vs gopher holes. Rat tunnels are usually only 3-4 foot long and run about 18 inches from the surface although they are sometimes deeper when going under any barrier such as a building foundation. The tunnels (burrows) are often interconnected with multiple entrance/exit holes.

Though there are many species of gophers they have similar tunnels. They are also interconnected and thus can have multiple entrance/exit holes. The gopher tunnel system can cover a very large area of 200 to 2,000 square feet with the main runway situated parallel to the surface and about 6 to 18 inches below the surface. Nesting and food storage areas of the tunnel system will be located as deep as 5-6 feet. Therefore gopher tunnels are much longer and can be more complex.

So there are differences in rat and gopher tunnels. They both however have multiple interconnected holes in the tunnel system.

Zyklon B was that not first used as a a rat poison? I know, I should not make the question from my SD name.
