We found that the strongest and most effective rat poisons typically contain bromadiolone or difethialone as their active ingredient. Slow-acting poison tends to be more effective than fast-acting poison because it won't deter other rodents from eating the bait.
FASTRAC BLOX with the active ingredient, Bromethalin, is Bell's fastest-acting rodenticide formulation.
Metal phosphides have been used as a means of killing rodents and are considered single-dose fast acting rodenticides (death occurs commonly within 1–3 days after single bait ingestion).
The only safe and viable method that will kill a rat instantly is a snap trap. Poisons can take up to a week to kill the rats and other types of traps will not provide an instant kill, and will even cause severe suffering.
Bait with Rodenticides
Bait stations using rodenticides (rat poison) are effective ways to get rid of rats permanently.
According to presently available information, rats can take up to a day or less to die after consuming salt. However, they will need to have eaten at least 80 grams (0.17 lbs) of it for the salt to be fatal. Rats cannot survive with more than 70 to 75 grams (0.16 lbs) of salt in their bodies.
There is no single food that will kill rats instantly. But there are a few foods that can become fatal to them when eaten in large quantities. These include chocolate, avocados, and peanuts. When you want to kill a rat, it is best to trap it and then drown or hit it on the head with a heavy object.
Brodifacoum - This is probably the 'strongest' poison you are likely to buy. It is a single feed bait, which means that the offending mouse or rat will consume a lethal dose at the first time of feeding. Its relatively fast acting with rats and mice dying within 3/4 days of consuming enough poison.
Raw onions can kill rats. While not a part of their regular diet, or a humane rat control technique, onions do have the ability to kill and temporarily deter rats.
Raptors, including hawks, owls, eagles and falcons, are common predators. Red tail hawks, found across most of North America, and American kestrels, the smallest falcon in North America, will hunt rats by day.

The EcoClear Rat X pellets are great for killing rats quickly. A more humane method, this formula kills rats with just one feeding. At the same time, there is no chance of secondary poisoning, so it is safer around people and pets. Not only is this product safe for your family, but it's also safe for the environment.
You need a fresh set because you have a higher probability that it might have expired. It's also possible that various factors, such as the storage conditions, might have reduced its effectiveness. Using expired rodenticide in such cases will help the rodent develop resistance to that particular toxin.
The active ingredient in rat poison is brodifacoum. It is used in baits to kill rodents such as mice and rats. It is sometimes referred to as a super-warfarin, because it is longer acting than the drug Warfarin.
Mixing chopped garlic with water and sprinkling it around your home or even spreading garlic cloves in the pathway of their regular trail can drive them away. The aroma of bay leaves attracts rats and they tend to think it as their food. However, when they try to feed upon it, they choke themselves, and eventually die.
Whilst in high amounts this is true (and also true for humans!) the levels that a rat is likely to eat by choice are perfectly safe. Aim for no more than one garlic clove per rat and a teaspoon of chopped raw onion, more can be fed of cooked variants. Both offer good health benefits particularly in the raw state.
Mice or rats die in 24 to 36 hours when exposed to baking soda due to its strong alkalinity, which is well beyond the levels they can handle. Baking soda is natural and mice or rats cannot discriminate between it and food. It does not have to mix with poison or other substances for mice or rats to ingest it.
The spray is great for both deterrence and cleaning up after rats. By mixing vinegar and baking soda you can actually create a poison that will kill rats. As with any poison however, you have to be careful when you handle it, and when you apply it.
Yes, you could technically kill mice with toothpaste, but it would be very difficult to get them to eat enough that it would be fatal. Apparently, mice that eat toothpaste that contains fluorine and ethylene glycol would die from those ingredients if they consumed enough of them.
Fruit and berries — Out of all the foods rodents consume, their top two loves are generally fruits and berries. In the wild, rats and mice consume these foods at every opportunity. Therefore, raspberry and blackberry bushes — as well as apple and pear trees — can serve as magnets for the animals.
So, specifically, what do rats eat? In the wild, they'll often feed on grains, seeds, nuts, fruits and vegetables. They might also eat smaller animals or insects, though this may be less common because it calls for hunting.
