What are rodenticides?
Rodenticides are a type of pesticide meant to kill rodents. It’s formulated as a bait that appeals to the taste of rats. This formula is designed to start killing even on a small amount, making it very potent and potentially dangerous for humans.
The best thing about rodenticides is it doesn’t leave any chemical smell on your home. It’s a rat poison that kills without odor, although it can’t help with the smell of dead rat if that’s what you’re thinking of. Rodenticides can kill rats, but once the dead bodies decompose, you’d have to clean up to prevent the smell from emanating from the remains.
Most rodenticides are packed with protein and sugar to entice the rats to feed on it. It’s basically rat poison masked as a tasty snack.
Rodenticides are not meant to be used in the open. You have to use a bait station where you’ll put the rodenticide. This will prevent children and non-target animals from accessing the poison.
Anticoagulant vs. non-anticoagulant rodenticides
Rodenticides are divided into two types: anticoagulant and non-anticoagulant.
Anticoagulants interfere with the ability of the rodent’s blood to clot. Since it prevents blood clotting, it will lead to internal bleeding and eventual death. Specifically, it interferes with Vitamin K in the rat’s bloodstream, which plays a big factor in blood clotting.
Some examples of anticoagulants used in rodent poison are warfarin, bromadiolone, difethialone, and Brodifacoum, among others.
With the way anticoagulant works, the rat will die a slow and painful death.
Unlike anticoagulants, the non-anticoagulants affect the nervous system of the rat. It alters the calcium levels in the bloodstream, which will lead to a slow death. For example, Bromethalin stops the central nervous system from creating energy, which will cause the nerve cells to swell. As the nerves press to the brain, the rat will become paralyzed and will soon die.
Some non-anticoagulants are single-dose, which means that it only takes one feeding to kill a rat. However, the likes of Cholecalciferol will require multiple ingestions to become lethal.
Other examples of non-anticoagulants are strychnine, zinc phosphide, thallium, and sodium fluoroacetate.
So which one is better? Both anticoagulants and non-anticoagulants work, but the latter only requires a small amount to kill the rat. This will let you save both bait and money, especially on massive infestations.
Benefits of using rodenticides
Unlike other pest control efforts, rodenticides offer a faster way to kill the rats. It’s also much safer for the people and pets around if used properly. The following are some of the perks of using this method:
✔️Cost-effective. A single-dose rodenticide will only require a small amount to become lethal among rats. With this, a single bait station can kill dozens, which will help you save money.
✔️Easy to use. Unlike chemical pesticides, rodenticides in the form of bait are easier to place. You simply have to put the chunk in the bait station and wait for the rats to forage. Some bait stations can be purchased with the poison already placed inside.
✔️Safer for kids. Rodenticides contained inside bait stations are safer for households with young children. Bait stations are designed to prevent small fingers from poking inside and touching the poison.
✔️Less effort. Once your bait is set, you just have to leave it alone and do its job. Make sure that you check any potential nesting site to dispose of dead rat bodies.
How to use rodenticides
Once you have a rat poison that kills without odor, the next thing to think about is how you’ll use it. When it comes to rats, you should avoid attaching your smell to the bait, or they will avoid it. You must follow these steps for the guaranteed kill:
Step 1. Get a bait station
You’re not supposed to put rodenticide chunk in the open. You must get a bait station or at least come up with a makeshift one.
Step 2. Fill it in
Open the bait station by pressing the release tab with your index finger. Once open, place the bait chunks inside. Make sure that you’re wearing rubber gloves as some rodenticides may cause skin irritation. Aside from that, your smell will attach to the bait and the station.
Step 3. Place it on the right spot
Once the bait station is all set, it’s time to place it around your house. Each bait station should be 8 to 12 feet apart for the best efficiency. Also, choose spots that are inaccessible to children and pets. Keep wearing the gloves until you’ve finished setting up the baits.
Step 4. Keep baiting
Keep filling in the baits for four consecutive days. Remember that rats would have to establish their foraging habits first, so don’t expect the pest to be gone overnight. Also, if you’re using a multiple-dose rodenticide, you will need to wait until the pests have fed on your bait multiple times. You must refill the bait regularly.
Step 5. Check for dead rats daily
A day after placing the baits, always check around your house for dead rats. For single-dose rodenticides, you can find weak rats the next day that are already on the brink of death. You can dispose of it right away to prevent decomposition and the bad smell.
Safety tips in using rodenticides
Although rodenticides are formulated to kill rats, it can also pose a risk to humans. Avoid any contact at all costs, especially to curious kids who might ingest the poison. To ensure that your rat extermination will succeed, you should keep the following in mind:
✔️Always wear protective gear. When it comes to rat poison, you should never take chances. Always wear gloves when handling the chunks and always wash your hands after.
✔️Patience is truly a virtue. Rats can bait-shy, so you have to be patient. One thing that you can do is getting them familiar with the bait station. You should add food first before putting the poison. This will let you kill more in the process.
✔️Read the label. Whatever pesticide you’re going to use, always read the label. Follow the instructions carefully and always pay attention to the manufacturer’s warning.
✔️Keep the bait tub sealed. Make sure that the bait container is always sealed and far from the reach of kids and pets. Keeping the bait sealed will also prevent it from going stale.
✔️Use gloves when disposing of rats. Rats are notorious carriers of various diseases. You must wear protective equipment when disposing of it, regardless if it’s still breathing or already decomposing.
✔️Mind the wildlife. Take note that rodenticides can also be poisonous to other wildlife. Make sure that stray and domestic animals won’t have access to the poison.
✔️Learn first aid. On the off chance that a child or a pet ingested the poison, you must know some first aid steps to prevent the poison’s spread in the body. Call 911 right away or rush the person to the hospital.
Rodenticide buying guide
When buying a rat poison that kills without odor, you must consider the following aspects:
Know your rodent
The first thing you have to consider is the type of rodent lurking in your home. You should look for long-acting, single-dose rodenticides that will start to kick in even at the smallest amount for large rats. Most potent rodenticides can kill rats and other pests.
Choose the right active ingredient
Next, you should decide whether you want an anticoagulant or non-anticoagulant formula. A non-anticoagulant rodenticide is more potent, which is ideal for large-scale infestations.
Remember that a 2nd generation rodenticides are more fast-acting than 1st generation formulas.
Every rodenticide has specific doses that dictate how lethal its effects will be. High-dose rodenticides are ideal for large rat species. Due to their larger bodies, it will require more poison to start killing the critters.
The larger the droppings, the larger the rats will be. This means that you need to increase the poison dosage as well.
Rodenticides should always indicate safety precautions to its label. It should include any potential allergic reactions, environmental effects, and other potential side effects.
Rodenticides are packed with toxins that should only be ingested by the pest you’re targeting. The manufacturer should also state clearly if the formula may cause secondary poisoning.
Value for money
Last but not the least, you should make sure that the rodenticide will yield results. This will give you the best value for money, especially if you’re purchasing multiple buckets of poison. A fast-acting, high-dose rodenticide will do the job for most infestations.

Frequently Asked Questions
Q: How long will it take for a rat to die when it eats poison?
A: It will take an average of three days for the rat to die upon ingesting the poison. Rats will also stop feeding once they’ve ingested the poison. This will reduce the possibility of secondary poisoning. Still, you should cover all food items and seal all utensils to prevent poisoning.
Q: How to tell if a rat is poisoned?
A: Poisoned rats that are on the brink of death will have labored breathing, weakness, and bleeding. Unfortunately, these are the same symptoms for pets that have ingested the poison.
Q: Where do rats die after eating poison?
A: Rats will not die in the bait station since the poison doesn’t take effect in an instant. You’ll never find dead rats on the bait if that’s what you’re expecting. Usually, the rat will go back to its nest, especially once it’s starting to feel the effects of the bait. One sign that the rat has died is once it starts smelling.
Q: Do rats suffer when they are poisoned?
A: If you’re curious, the answer is yes. Rats will die a slow and painful death when you poison them. Usually, it will take up to three days for the rat to die due to the poison’s effects and its complications. Anticoagulant-based baits will cause internal bleeding, which will not kill the rat instantly, making the pest suffer.
Q: Is there a safe rat poison?
A: Rat poisons are meant to be harmful to rats, but you can find formulas that are safe to use around children. Still, the fact that rat poisons are meant to kill means it’s not safe. You can try using diluted ammonia to kill some rats, but it doesn’t guarantee solid results.
Although rat poison that kills without odor doesn’t necessarily remove the stink of a dead carcass, it helps reduce the chemical smell of the extermination. The options I reviewed here will help you get rid of the pest without trapping or hunting them down. The baits will trick them into their own death in just a matter of days.
