Rat/ Mouse poison Bromodiolone

[Malc]

Can anyone help?

I have a mouse problem in the toolshed. It is some years since I had an infestation so I cracked open a sealed container of Endorats Bromodiolone based killer.

The killer is out of date by four years, but was kept cool and dry and the mice love the stuff. Not a single dead mouse in three weeks and the bait is going down rapidly.

Is it the poison that degrades or as I suspect the bait, which is grain?

I am well on my way to emptying the container and must buy more, but is the poison ineffective or might the mice be resistant?

If the reason for the date expiry is to ensure that the grain remains attractive to the mice, then obviously the mice are not unhappy anyway.

Has anyone experience please?

Bromadiolone is an anti-coagulant. It's supposed to act faster than Warfarin and vermin that ingest it are supposed to die within 24 hours. Even though you probably won't see dead mice, the nest should die out pretty quickly.

This: "The results of field tests with grain and pelleted baits showed that bromadiolone degraded by 78 and 45% respectively over a

21-day period" from . After four years it will have lost its effectiveness; they're probably loving it! More here if you're interested

Thank you Chris.

I did look before I posted. Sadly it seems my abilities are not too good in that department.

Anyway, I am grateful, I will buy some fresh stuff today.

Thanks

You bought Endorats. Should you buy Endomice this time?

So where is it going? I'd have thought these days you need to be careful you are not killing other wildlife. Brian

Although it will only get them one at a time, an old-fashioned spring trap is usually pretty instant and more humane IMO.

It did concern me. I am using the approved containers, but am not sure if there are any dead rodents being eaten.

I gather the poison contains a chemical that makes it unpleasant to other creatures.

I will also put some traps down!

Thanks

When I had a mouse problem in the house a lot of poisoned bait seemed to be disappearing quickly over a period of around a week. I never saw a dead mouse but the problem did go away. A few months later I was doing some work under the floorboards and founds a fairly large stash of blue coloured bait.

I went to my local hardware shop to buy some mouse bait, the assistant recommended a pasta based one, Pest Kontrol made by Unichem, saying the mice love it!

At £3 for 120g it was considerably cheaper that the others despite being somewaht sceptical i bought a box.

I got home and put some out and within 3 hours one of the sachets had gone. The others are still there undisturbed after a week.

Who would have thunk it, gourmet mice?

Mice are small and dryout quickly not enough to feed many maggots. Have found several dehydrated mouse corpses over the years with no hint that something had died. Apart from the one under fridge, but that was in a warm place.

Poisoned rats on the other hand...

I would like to thank everyone for their help.

It's over four weeks on from initial baiting and I posted the help request after yet another dollop had gone.

I checked the container and that is 750gm that was "eaten".

The stuff I put down Tuesday hasn't been touched.

There is no rustling as I open the shed door now either.

I am starting to get hopeful
