How Does Rat Poison Work?

Not many people consider why a particular rat poison works or not. All they care about is whether the product gets rid of their personal rodent problem. However, it may actually be beneficial for people to think about how a particular rodent poison works. After all, not all of the active ingredients in mouse poisons are the same, so having at least a basic understanding of them can be quite useful. With that in mind, let’s take a look at some of the more common chemicals used in these products.

Anticoagulants – Poisons in this category probably make up the majority of the rat killing products out there. And they work in a pretty simple way. They work by affecting how rat’s blood clots. It starts reducing Vitamin K levels the moment the rodent ingests it, and within a couple of days, the mouse or rat has died of internal bleeding.

Bromethalin –  his the next most popular chemical found in poisons for rat control. After ingestion, this product begins to immediately damage the mouse’s central nervous system, but that’s not what kills the mouse. No, it’s high sodium levels accumulating in the rat’s liver that eventually does them in.

Metal Phosphides – These are rather unique poison products. These metals produce a strong garlic odor, which surprisingly attracts rats. However, it’s not used as frequently as some of the other products on this list. These poisons kill off rats by forming a toxic gas in the rodent’s stomach which ends up killing them in only a few days. Within a week, the poison ends up killing the rats.

Calciferols – This product probably takes the longest to kill the mice of any of the other poisons, but that doesn’t mean that it’s not extremely effective because it is. It works by increasing the Vitamin D levels in the rodent’s system. This causes a severe calcification of the rat’s heart, brain, lungs, and kidneys. Within a week, the poison ends up killing the rats.

How to Poison Rats Effectively

Once you’ve chosen the best rodent poison for your home, garage or workshop, it’s now time to use the poison in the correct manner. And what I mean by correct manner is in a way that will enable the rats to find and ingest the poison, but will keep the poison out of reach of children and pets. Keeping that in mind, here are some tips for using pest poisons effectively.

Read Instructions Thoroughly – When you bring home a rat poison, particularly one that you haven’t used before, be sure that you read all of the instructions. And I do mean all of them. Sure, it may seem boring, but that’s the only way that you’ll know how to safely handle the product. And if any of your rodent poison’s instructions contradict the tips in this guide, then your product’s instructions and advice should be what you follow.

Identify Problem Areas – Make sure that you do a complete audit of your home and property. Just because you’ve only seen rats in one particular room doesn’t mean that they aren’t in other areas. The first thing you’ll want to look for are any entry points into your home like mouse holes or outside burrows. Then you’ll want to do a room-by-room survey of your home. You’ll be looking for rat feces, which resemble dark grains of rice, damaged bedding or packaging and other tell-tale signs of a rat infestation.

Fill In Burrows & Fix Rat Holes – If you’ve found outside burrows, be sure to fill those in with dirt. If you’ve found rat holes in your baseboards, you can place rat poison into the hole and then seal it up.

Seal Other Access Areas – Check your foundation for cracks. Rats can squeeze into any hole as small as an inch wide. Also be sure to caulk around plumbing and other access areas.

Clean Rat Infested Areas Thoroughly – Any area in which you’re placing poison should be thoroughly cleaned. That means not only removing food scraps from off the floors or from behind cabinets. That also means removing anything that the mice may use as a food source. After all, you want the mice to eat the poison and not anything else.

Trick the Rats – Sometimes it’s helpful to place food items which look like the poison on top of the poison. That’s because rats are naturally wary of new items in their environment. However, once they’ve sampled the food items and discovered it was safe, they will continue to come back and eat the rest of the food and hopefully, the poison.

Use A Variety of Rat Killing Products – Several different types of poisons can be used in the same area, just be sure to space them out a bit and keep them out of reach of children and pets.

Rodent Poison Safety Tips

These safety tips are probably going to be repeated by your poison’s safety warnings, but it’s important enough to repeat them here. Rat poisons are extremely toxic to humans and animals, so every precaution must be taken to keep these products away from people and pets. Here are a few more safety tips:

Keep Poisons Stored Securely – Make sure that you keep all of your rat killing products not only out of reach of children and pets but locked away. You can never be too safe securing dangerous poisons, so take every precaution possible.

Keep Poisons Away from Children – Yes, I’ve already said this but I’m going to say it again. When putting poison out for rat consumption, be sure that children and pets can’t get to it. This means placing it in areas completely inaccessible to both children and pets.

Keep Poisons Away From Foodstuffs – You also will want to ensure that your poisons are somewhere that they can contaminate not only your foodstuffs and water but also your pet’s foodstuffs and water.

Use Product As Intended – This means following ALL instructions on the product’s label. And it also means that if a product says don’t use in homes or other residential settings, that you don’t use it for these applications. It also means that if the product says don’t use outside, that you refrain from using it outdoors.

Take Precautions – The final thing to note is that you should take precautions when placing poison. This means wearing safety goggles, a mask, and rubber gloves. This may seem excessive, but some poisons can be absorbed through the skins, and mucous membranes, so proper precautions should be in place.
