Best Rat Poison – What You Need To Know

Getting the best rat poison to eradicate your rodent problem can be a challenging task to accomplish. Let’s face it, nobody likes rats, and most people consider them to be a pest. There are so many brands on the market to choose from and trying to select the right one can be a daunting process.

You need the most effective rat poison that can stop the rodents from breeding and enable you to regain control again. If you get an inferior product, the problem could just get worse, and before you know it, you are now in a worse situation to when you started.

What is Rat Poison and How Does it Work?

Rat poison is a combination of chemicals that aid in shutting down a rat’s body when they consume it. Rat poison pellets are the most common form that you will see, and you can also get rat poison available in blocks, bars, and chunks. The best mouse traps can also be available in similar forms and are made in the same fashion.

Rat poison originally used to contain toxic chemicals that were harmful to humans. We used to have to evacuate premises and wait for these chemicals to clear, so it was safe for us to enter again. Technology has rapidly progressed over the years and we have managed to reduce the harmful effects that rat poison can have on humans.

You can find that the best rat poison will contain anticoagulants which aid in thinning the blood. Once the poison is ingested by a rat, it will cause internal bleeding, and the rat will go into shock.

You will find that the best rat killers have a design similar to this and as bad as this method of extermination sounds, the rat dies quickly with minimal pain. This isn’t to say that rat poison is safe for humans to be around and you should use adequate protection such as gloves when handling it and keep your children away from the contaminated area.

It is still very toxic to humans and almost certainly will kill a person if they ingest it.

Some rat poisons contain non-coagulants and instead carry a different form of toxic chemical to kill the rat, read about rat repellent‘s here. Bromethalin is an example of this, and it affects the rat’s central nervous system by causing a substantial decrease in adenosine triphosphate which in turn raises intracranial pressure.

The rat’s central nervous system is severely damaged as a result and paralysis, convulsions, then ultimately death will follow.

How Do I Know If I Have Rats?

Rats love to hide and live in the internal structure of a building. They build their nest and breed behind the scenes, and you may not even know that you have a rat infestation until it’s too late.

While it is very possible just to have a single rat who has found their way into your premises, there is still a good chance that there could be more. If you find a dead rat or see one roaming around out in the open, chances are there’s more not far away.

This is because once they multiply, their living space becomes smaller and forces them to move around more. If you see droppings, then you most likely have a healthy and thriving rat population on your hands.

Why Do I Need To Get Rid of Rats?

You may think that rats are harmless or even a bit cute, but they are known to carry diseases, and they can transmit them to humans too. Just the urine from a rat is capable of spreading leptospirosis, which is known to cause kidney and liver damage.

It’s also possible to contract this through the inhalation or handling of their feces. Another disease which is transferred through a rat’s urine and also their saliva is lymphocytic choriomeningitis (LCMV), which is a neurological disease with a typical onset of 8-13 days.

Rats are also famous for greatly assisting in spreading the bubonic plague of the Middle Ages, known as The Black Death, which resulted in the deaths of over 50 million people in Europe.

There are two ways that diseases can spread from rats to humans;

  1. Exposure to urine, bites, or infected feces.
  2. Transmitted via ticks mites and fleas which live on the rat.

Hantavirus Pulmonary Syndrome, Rat-bite Fever, Salmonellosis, and Leptospirosis are all transmitted via direct contact with a rat in the form of a bite, scratch, urine, feces, or inhaling or consuming contaminated dust, food, and water.

The Plague, Cutaneous Leishmaniasis, and Colorado Tick Fever can all be transmitted from rats to humans indirectly. This is done through ticks, fleas, and other parasites which come in contact with you and have previously been in touch with a rat carrying these diseases.

How Can I Get The Best Rat Poison and Fix My Problem?

Did you know that rats can learn from their mistakes when it comes to setting traps for them? Rats are quite observant creatures, and if one of them sees another one get harmed or die because of a trap, it can take notice and remember this and avoid that trap because it knows what will happen.

They are smarter than we give them credit for, and rats have also been known to leave feces or urine around a trap so that other rats know not to go near there. You can also adopt a technique called “pre-baiting.”

This is when you leave non-toxic bait out for the rats to consume so that they can become accustomed and more trusting to bait. You then phase in the toxic bait once you notice that all the non-toxic bait is getting consumed and your rat should more than likely consume it.

If you are in a situation like this, then you need to get the best rat bait that you can find. Rats breed fast, and they can multiply at an alarming rate. An average litter is 8 – 10 rats and the gestation period is approximately 21 – 24 days.

If you have multiple rats capable of breeding and carrying young, then you can find that there could easily be over twenty new rats infesting your premises every month. This is why it’s so important that you get the best rat poison that you can find and eradicate your problem as soon as possible now that you know how fast and easily it can spread.
