We Recommend – JT Eaton Bait Block Rodenticide

For sheer effectiveness and product trustworthiness, JT Eaton 709 is the best mouse poison that we recommend. This product has proven time and time again to be effective against rodents with a low-toxicity risk to humans and pets.

The Different Types of Mouse Poison

Mice poisons are typically divided into two types, anticoagulant antagonists and non-anticoagulant poisons. Both types of poisons for mice are effective, but there are drastic differences between the two in terms of potency, toxicity, and the length of time it takes to kill rodents.Â

Whichever type of poison you choose to utilize, caution should be exercised to avoid possibly dangerous side effects for yourself, family members, and pets.


Although many people find success in killing mice with mouse poison pellets, it is important to remember that rodents can be fickle and unpredictable. It will take some patience as well as precision to adequately eliminate a rodent infestation, which is why it is crucial to find what is the best mouse poison that works for you. You may find that anticoagulants provide adequate enough solutions, but the long time it takes to slowly kill the rodents may not sit well with you.


Non-anticoagulants will kill rodents quickly and in some cases, instantly depending on the type of poison used. To ensure you and your pet's utmost safety, slow-acting anticoagulant mice pellets and mouse poison blocks are strongly recommended, unless you live alone and are the only person or animal that knows where the poison is hidden.

What Can Kill Mice Instantly?

If you would like to kill mice and rats instantly, then we always recommend snap traps and modern electric versions

But, in terms of killer poison, the dangerous, yet incredibly potent non-anticoagulant group takes the mantle. These chemicals, such as strychnine, bromethalin, and sodium fluoroacetate, work by poisoning the central nervous system of rodents which causes almost instant death after ingestion.

How Long Does it Take a Mouse to Die After Eating Poison?

This can vary depending on the type of poison used and how much of the poison the mouse actually ingested. Anticoagulant rodent poisons are not like traditional poisons, which are usually repellent to rodents. Anticoagulants will take time to poison a rodent's system, so it is important to have patience during the process and be sure to refill the bait once you notice it missing. Anticoagulants generally take 2-3 days to kill mice and 3-6 days to kill rats.

No exact time table can be given because rodent's systems may vary depending on different factors. Rodents can be picky about certain types of bait, so do not be surprised if you notice the bait has not been eaten in a day or two. Also, the larger the rodent, the more time it will take for internal bleeding to completely poison the rodent.

What Foods Kill Mice?

Mice love all types of food and this is usually the number one type of bait that is used to lure mice into traps. According to the Indiana State Department of Health:

“Permethrin treatment of is an effective, inexpensive public health measure to reduce mosquito bites. Permethrin is effective among all individuals in all settings and is more effective than topical insect repellent alone.â€

Indiana State Department of Health

This means that rodenticides will frequently mask their poisons inside of blocks and pellets that mimic these food types to attract rodents to eat it.

What's the Difference Between Single Feed and Multiple Feed Rodenticides?

Anticoagulants and non-anticoagulants are further divided into how long it takes rodents to die once they eat the poison. Anticoagulants are frequently classified as multiple feed options since it takes multiple amounts of the chemicals to build effective levels in the rodent's circulation system. These poisons can take many feedings to get just the right level of poison into the bloodstream to kill the rodent, and the larger the rodent, the more time it could take.

Nonanticoagulants are incredibly toxic and will usually kill rodents after one feeding. Even though this may seem like a benefit, it can be very dangerous to have these poisons sitting around your house. Although anticoagulants take longer to work, they are certainly the safer option.

In Summary

These six featured mouse poisons represent some of the best selections currently on the market. They are diverse in their own particular ways, but most of them share the chemical class of anticoagulants, which work by preventing blood clots to form in the rodent circulatory system, causing internal bleeding in a matter of days.Â

Non Anticoagulants work by poisoning the central nervous system of rodents, although these types of chemicals can be potentially lethal to humans and pets.

No matter which product suits your needs, you will likely find that each of these products will certainly fix the rodent infestation that has overtaken your home. Wether you decide to choose a single feed or multiple feed product, always be sure to follow the product instructions explicitly.Â

Mouse poison is certainly an option if physical traps either are not addressing your problem or seem too gruesome to utilize.
