best mouse poison

An infestation of mice needs quick action to prevent serious damage to any property. Mice breed fast and before you know it you could have a major problem to deal with. Traps are an excellent method of resolving this type of issue, but sometimes poison is needed to get it under control.

After an infestation at my own property, I was forced to resort to poison. This was done by a professional, but he also explained the best ways to use poison if ever I needed to in the future. This guide will give you information about some of the best mouse poisons on the market, based on our own knowledge and on customer reviews. We’ll also explain the best ways to use it and things you should be aware of.

How To Use Mouse Poison

Mouse poison should obviously be used with extreme caution. If used incorrectly it could make other animals very ill indeed and in some cases could kill them too.

The best way to use your poison is in a bait station. This is a plastic box with an entry and exit hole. The bait is placed securely inside the box and has a pleasing smell to attract the mice. They go in the box, feed off the poison and then it starts to work. If the mice are nesting, they can also take the bait back to the nest, and this kills all the mice there.

The idea behind a bait box is that:

  • The poison is kept safely inside the box
  • Other animals and children cannot get to the poison
  • The box can be left down all year round to keep further infestations at bay

There are several good poisons on the market, and here are just a few of our top picks.

Using Mouse Poison

Whenever you use poison, there are some basic rules of safety.

  • Always store securely when not in use so others cannot accidentally get to it.
  • Keep well out of the way of animals and children.
  • Never scatter loose pellets.
  • Always check the area you are planning to use the poison to make sure that other animals won’t be affected.

If your pet or child accidentally ingests some mouse poison, seek medical help immediately. Not all poisons will kill other larger pets or children but they can do serious damage if left untreated. Proper medical attention will mean that they get the right treatment to counteract the effects of the poison.

Using a Bait Station

Bait stations are by far the best way to use mouse poisons, and in some areas of the country they are the only way you can use them.

Bait stations hold the poison securely so there is no danger to other animals. Smaller rodents such as voles or small rats can often access the poisons but household pets cannot.

Bait stations can be used safely in any room or in the garden, outhouses, boats and RVs. Many businesses use these permanently to help control the mouse population.

  • When setting up your bait station, you should follow the same rules as setting a trap. Look for signs of mouse activity and place the stations next to the wall where they run.
  • Check the bait regularly. If it has gone, replace it. If it looks old or has gone damp, replace it.
  • If you keep your bait station out all year, check it every 6-8 weeks and replace the bait as required.
  • If you see signs of mouse activity elsewhere, you can simply move your bait station.

Types Of Poison

There are several types of mouse poison available but the two most commonly used are anticoagulants and metal phosphides.


These are the most common mouse poisons. They act by stopping the mice from forming blood clots and this eventually causes death. There are many different types of anticoagulant and some of these can take up to 2 weeks to kill a mouse.

Some anticoagulants, such as warfarin, will not kill a mouse with one dose, so you will need to keep the poison down until you are sure the infestation has cleared.

Metal Phosphides

This type of poison usually works within 3 days. The phosphides contain zinc, and this creates a poisonous reaction in mice. If mice don’t react to anticoagulants, metal phosphides are the next best option.

Disposing of Dead Mice

One big drawback of using mouse poison is that there is no guarantee where and when the mice will die. Most often they return to the nest and die there but there are occasions when you may find a dead mouse on your property. Don’t leave it where it is, because if it has eaten poison it can harm a cat if it then eats the mouse. You also don’t want dead mice around your children as the bodies carry harmful parasites and disease. Instead use these simple tips to get rid of it.

  • Never handle a dead mouse without using gloves.
  • The mouse can be thrown away but wrap it carefully and make sure nothing can take it out of the trash.
  • If you have found the mouse inside the house, thoroughly disinfect the area where you have found it.
  • Be careful of sweeping up any dry droppings, as these can spread dust and contaminate the air.

Good Luck!
