Is rat poison a good way to contain the infestation of rats? Or is it dangerous? Before you decide, I want to give you my 5 biggest dangers of using rat poison.

There is no doubt that rat poison is a successful way of dealing with a rat infestation problem, but it is not the only way to do it. There are more ways to skin a cat, is the saying.

Using Rat Poison – 5 Things You Need To Be Aware Of

5 Dangers Of Using Rat Poison Infographic

1. Kids

Rat poison can be very harmful to kids. When you leave packets of poisoned bait around your home or outside your property, you introduce something new into the environment. You know what kids are like when they see something new. they want to explore, don’t they. They want to get involved.

If a child were to ingest rat poison, they would need an immediate medical intervention! Many brands of rat poison contain Anticoagulants that basically stop the blood from clotting and results in the rat ‘bleeding out’.

If you decide that rat poison is your method of choice, I urge you to use child-friendly poison.

2. Pets

Pets will also need immediate medical treatment if they ingest rat poison.

Some folks use rat poison by throwing sachets of the stuff into open areas. They would then leave the rat poison in these open areas for the rats to eat. I was horrified when I saw a professional pest company do this. There was no concern about any pets or any other local wildlife.

Always put the poison in a place where your pets cannot access it.

3. Dying In Walls

Imagine this: A rat takes a stroll around your home (probably in search of food, warmth, shelter) and stumbles upon a sweet-smelling bag of poison. It’s going to do one thing. The rat is going to eat the poison.

What does the rat do next?

I know, it thinks ‘I am going to stick around here, there are free food and shelter. I know what, I will use these cavity walls to travel around this house; they will keep me protected’.

You know what happens next, don’t you? That’s right, the rat takes a turn for the worst, and dies inside your cavity walls.

You don’t know this has happened…yet. But you will know. In a few days, if the weather is warm enough (longer if it is cold), you will begin to get a small scent of something terrible. Over the next few days, the odor gets worse until it is unavoidable.

When a rat dies inside your cavity walls, there are 2 options:

  1. Go through the wall and dispose of the dead rat. This is very, very expensive.
  2. Ride it out. It will take weeks…

It would help if you did all you can to stop a rat from dying in your walls. Prevention is better than a cure.

4. Birds

Rats have one awesome natural predator. Birds of prey!

They circle above, looking out for rodents. As soon as they see one, they swoop down, grab the rodent, and take it away for a feast. Good job! That is one less rat for you to worry about.

What if the rat had just ingested poison? What will happen to the bird?

I’ll tell you, the bird has a high chance of dying. Now you have one less rat (good) but one less predator for rats (very bad). And, you have killed a bird.

5. Other Pest Infestations

It is not just rats that carry some terrible diseases; it is other pests too.

Now, imagine a small number of rats that are dying around your property. What is that going to do? It is going to attract other pests, such as flies and cockroaches.

An infestation of rats is bad enough, but now you have roaches, flies, and tons of other annoying little pests around your home, spreading diseases!

  1. It made a lot of sense to read the part of your article that stated that a rat dying in a wall from poison can cause foul stench down the line. This made me rethink my plan to exterminate the rats already in my home to prepare for the holidays since the idea of having a foul rat stench while hosting a dinner party does not sound very nice. To be on the safe side, I’ll look for a professional pest control service instead and get them to help me.
