The Better Mouse Trap

Recommended Posts

You always hear about how deadly Barium Carbonate is, and that it is used in rat poison.

Say a person;[hypothetically speaking], had mice in their cottage. The mice were snacking away on the store bought poison.Could a person lay down some barium? How much?

I have also heard it used for ants, 50/50 with sugar. [Called Ant Rid.]

TJR.

Anyone try this?

Tom,

 

I can't speak on rodents, but for ants, there is a safer choice. Mix a syrup,mor sugar solution with boric acid. Put some on a small piece of tag board (like an inch by ab inch), and place it in an area, where you have seen ants. Within a short amount of time, you will see the ants swarm the mixture. A day or so later, there will be none. They take the mixture back to the colony, and eventually it gets dispersed among all of them.

 

Use a bit of caution with the boric acid, as it can irritate the skin.

The BC causes internal hemorrhaging and bleeding.... that is what kills the mice/rats.  You'd have to get them to eat enough of it. The blood loss makes them thirsty.... which is the theory that they will go outside to find water and die there... instead of in the walls of your house.

 

The LD50 (the amount that kills 50% of the test subjects) for rats and mice is about 500 milligrams per kilogram of weight. (0.500 grams)  The average mouse weighs about 50 grams....or .05 kilos.  So they need to eat only a tiny amount........ a little over 2 and a half/100's of a gram. 

 

You'd have to mix it with something they like to eat and hope the BC doesn't add a flavor they don't like enough to avoid it. 

 

Personally...... I'd just got by a trap or some RidEx. ;)   Easier.

 

BTW... assuming the same LD50 is valid for humans...... for an LD50 dose to a human of about 175 pounds...... or 79.5 kilos....... you'd have to ingest about 40 grams of barium carbonate to have a 50% chance of living thru it to tell the tale.

 

best,

Now I feel bad. I think I'll just get some Ridex.

Always informative,John,

My cats do the trick. I would rather not use poison around my pets.  My semi feral cat killed 30+ rats this year and I haven't seen any since March. We seem to have had a bloom after some people moved out of an unsecured house with garbage.

She delivers them to the door. Unfortunately she got some 2 bats too. We don't have rabies in the area, so I am thankful for that. We do have nutria.

They are much bigger than my dogs! But pretty harmless.

According to the one article from the digital fire MSDS area, the last known accidental human poisoning from barium carbonate was back in the first part of the last century, due to food contamination. It didn't say how, but some sort of sausage (strongly flavoured?) got contaminated in Israel.

I think dynamite is a better mouse trap. Just a few sticks placed in small cottage should do it. Placement does not really matter.

If this is to extreme heres another wacky idea-

Mouse tried and true technique is smoke them out. You could try a raku barrel in kitchen and feed until whole cottage is full of dense smoke-leave one door ajar and stand by with your shoe and wack them as they run out-a tennis racket also works.This whole idea is like smoking bees if you have ever worked hives-the more smoke the better.

Gohpers issues well thats another thread altogether.

 

One last resort is go to hardware store and buy a few mousetraps.Less damage than above two techniques.

I prefer the zap treatment. http://www.amazon.com/Victor-Electronic-Rat-Trap-M240/dp/B000LNX06C/ref=sr_1_3?ie=UTF8&qid=1436148115&sr=8-3&keywords=electric+shock+rat+trap&pebp=1436148126835&perid=0JF3XCHV8M06KX4QHXPJ

 

Works like a charm, been using it for 2 years now. It's awesome as long as you change the batteries after so many kills. I have a shed out back that I had some rat problems with. I had some birdseed in a bag I forgot to put in a plastic bucket. Needless to say i went out there one day and a bunch of rats were hanging out, weren't even scared of me, just walked off the floor and climbed the walls. After about 2 weeks of killing them constantly with this trap every night, I no longer have rats. I also put out some decon and found some outside dead as well. But I kept it off the floor and up in the rafters of the shed. 

 

Been rat free for about 6 months now. I keep the zapper on, just in case.

The sonic things work for mice. I can't say about rats because I live in a rat-free province. Yes, this is a real thing.

 

And a really morbid part of me finds it hysterical that Amazon offers gift wrapping on that zapper.

Castor Bean plants keep gophers away and they are attractive. Surround your garden with them. How can Alberta be rat free? Interesting. I think there were rats in Montana but I don't ever remember seeing any. Definitely had mice. We used traps. One night they were snapping the traps as fast as we could reset them. Coming in along the washing machine pipe from a crawl space. In the previous house , again my cat took care of any mouse house invasion.

I guess I have lived in more rural settings. We had the sonic mouse things in our Artists' resident house, but the director brought the mouse into his huge shop for the winter and fed them. Iceland is a strange place where contractors need to get an environmental impact statement for elf free zones. Really.

There's provincial grants for pest control, and since Norway rats cannot survive without humans and their buildings, the sparse populations and or mountains on the various borders make their migration slow and controllable for the most part. There is the odd issue, but they get cleared out pretty quick.

Marcie;

This kind of went south. I wouldn't want to trap any elves in my trap.We had one grad student at Alfred who built a cute little house for the mice and was feeding them. Tony Hepburn got wind of this. It didn't last long.

TJR.
