Dekers Posted November 13, 2013 Report Share Posted November 13, 2013 (edited) So in terms of wheat based bromadiolone does a rat need to injest in terms of the wheat by volume to expire? I don't understand the question............... but if you are asking how much wheat a rat needs to injest to kill it, that will depend on the weight of wheat it eats and the % of Bromadiolone present in the wheat, that would commonly be 0.005% Bromadiolone concentration in wheat, so weigh the wheat and when you get to 1.125mg/kg Bromadiolone by body weight of the rat more than 50% of the sample rats will die.

turbo33 Posted November 13, 2013 Report Share Posted November 13, 2013 A client of mine was fairly high up in Shell oil. We were discussing rats one day and he told me of a poisons subsidiary company that Shell owned. The scientists at the unit contested the theory that rats had become immune to Warfarin. They discovered the rats were actually communicating with each other to make the others aware of the poison and thus avoiding ingesting it and not immune at all. The difficulty in overcoming this was, that a poison acting quick enough to kill the rats before they could communicate with others, would be inherently to dangerous to use. So they were working on additional toxins that would disable the rats ability to communicate with others until the Warfarin had taken effect. In the meantime, the only way of out foxing them is to continually change the recipe until they catch on, then you have to change again.

karpman Posted November 13, 2013 Report Share Posted November 13, 2013 Was out ratting last night looking a water trough with a good size rat whole at the front. Old whiskers pops his head out and looks at me pop head shot a few twitches dies in the the mouth of the hole. No worries a run out of either side they like to appear from too and learnt that if you keep the beam on the whole edge they pop out and stop. Well was watching when the dead rat disappeared back inside the hole and another comes out the same entrance pop dead. Hole partially blocked 10 minutes later rat disappears and another pops up and was swiftly dispatched. Went down at dinner to find the other two holes blocked with bedding and bread mash so got the fork had a dig around and found poison plenty of it too were the farmers wife had tipped it into the wholes they had practically blocked them selfs In to avoid it. After digging some I couldn't locate the shots rats and I assure they were very dead lol. Karpman Quote Link to comment Share on other sites More sharing options...

Unnervingly clever things rats i once saw an experiment where 9 different foods were lined up and a single rat was allowed to chose what to eat, the first few refused all but eventually one chewed on a cookie after that every rat released chewed on that cookie and all ignored the other 8 food sources, very keen sense of self preservation Quote Link to comment Share on other sites More sharing options...
GingerCat Posted November 20, 2013 Report Share Posted November 20, 2013 My mate had a goat and the barn got overrun in very short order, the goat was moved and the door left open for the cats to pop in or out. Less than a week later the rags were in pieces all over the place, think his cats were part terrier. Get s cat,or terrier and let them get in with it.

carpentermark Posted November 20, 2013 Report Share Posted November 20, 2013 Why don't you put some broken Mars bars out in a specific 'safe' place for a few nights till they're used to feeding then have a night on them with a .22 air rifle and lamp? legal, humane and fun!

I suspect because most know that's more likely to lead to an increase than a decrease in the Rat population. One thing we shouldn't ever do is treat it as some sport. You need them all dead ASAP leave just one pregnant female and your facing fast population rises. By all means pop a few with the gun while the poisons etc take effect but it should never be a primary method. Quote Link to comment Share on other sites More sharing options...
GingerCat Posted November 20, 2013 Report Share Posted November 20, 2013 Would never waste a Mars bar on a rat. Whatever next...... Especially when's there nutella spread or cat food that does the job and Roland can't carry it away. Quote Link to comment Share on other sites More sharing options...

Proudly Posted January 21, 2014 Report Share Posted January 21, 2014 £1500 for drowning a squirrel? Maybe the fella should go all out on a squirrel control mission but consider using tunnel traps instead of a cage. Then let the RSPCA have updates on how many have been killed 'humanely & efficiently' Quote Link to comment Share on other sites More sharing options...
robbiep Posted January 21, 2014 Report Share Posted January 21, 2014 (edited) £1500 for drowning a squirrel? Maybe the fella should go all out on a squirrel control mission but consider using tunnel traps instead of a cage. Then let the RSPCA have updates on how many have been killed 'humanely & efficiently' However, due to the fact that the bloke concerned now has a conviction under WACA or other wildlife legislation, he is now prohibited from using the general licences (for 5 years, I think) Just goes to show just how critical it is to know the law, and then obey it. Much like the constant questions about air rifles and foxes. A simple readthrough of the Home Office police firearms guidance document shows that, quite clearly, FAC air is NOT suitable for fox, yet we see people saying they see nothing wrong with it time after time, using sub-12 air rifles If caught, then they would probably face prosecution under animal welfare legislation, conviction results in a ban on using the GLs for a considerable time.

pestguard1 Posted January 23, 2014 Report Share Posted January 23, 2014 Barbaric and I think illegal: Very illegal , just because they are rats , they do have rights , they have a legal right to be dispatched cleanly , quick , and most important ......HUMANELY "Rural Development Service’s (2006) advisory note on rat control which stated that: ‘Drowning is not a humane method of dispatch and could result in prosecution…" Quote Link to comment Share on other sites More sharing options...
timb Posted February 22, 2014 Report Share Posted February 22, 2014 Get caught drowning a rat, and you'll have a big fine to pay. You should use your license too. If you can't kill it properly don't bother to trap it. You're just what the antis like to hear about. Pillock. Quote Link to comment Share on other sites More sharing options...
