Rat Poison Buyer’s Guide
Pets and Rat Poison
If you have cats, dogs, or other free-roaming pets that might encounter the poison directly or consume the rats after they have been poisoned, you should always avoid using any type of rat poison. The risk of accidental collateral damage with most types of rat poison is significant, and for the safety of your pets (or small children!), it is essential to avoid this risk entirely by using non-toxic methods to eliminate a problematic pest infestation.
Rat poisons are designed to kill rats and other pests, meaning that they contain a range of unpleasant toxins. While some rat poison options are formulated to be specific to rodents and have no effect on other creatures, many contain broad-spectrum toxins that can cause illness or, more likely, death in other animals that consume the poison.
This can also apply to secondary poisoning; if a rat eats poisoned bait and then a hawk or other predator eats that rat, then the poison will enter the bloodstream of the predator and will in all likelihood kill it. This means that rat poisons used without care can cause a significant ecological impact, killing far more than just the rats.
As such, it is essential that you follow all safety directions for use on the packaging of your rat poison. These directions will always be present, as they are required by US Environmental Protection Agency regulations. If your chosen rat poison does not feature these instructions, then it does not conform to these regulations and could contain all sorts of dangerous and environmentally harmful substances and should not be used under any circumstances.
If you have cats or other free-roaming pets on your property, you should avoid using any type of rat poison, as the risk of cross-contamination or accidental exposure is significant no matter how carefully you use your poisons.
All poisons have specific lethal doses, meaning that you need a particular amount in order to kill the target. The problem here is that rats and mice are very different sizes and have different physiologies, despite both being rodents, and therefore the lethal dose of each poison required to kill them will differ between mice and rats.
As a result of this, it is essential to determine what type of pest you are dealing with before purchasing a poison; if you have mice, then use a mouse poison, but if you have rats, then use a poison formulated especially for killing rats. The size of the droppings you find in your home can provide a good indication of what type of pest you are dealing with, with rat droppings being noticeably larger than those of mice.
How Does Rat Poison Work?
Different types of rat poison work in different ways, killing rats in a wide range of different manners. Some types of rat poison contain the toxin bromethalin, which interacts with the mitochondria of the rodents’ cells, inhibiting their ability to produce energy and effectively shutting down their bodies completely.
Other rat poisons contain zinc phosphide, a toxin approved only for use in agricultural areas and not appropriate (or legal) for domestic use, which causes a reaction in the stomach acids of rats and mice, causing the production of toxic gases, which build up until the rodent in question dies.
A third common type of rat poison is that which contains calcium releasers, adding an excessive amount of calcium to the bloodstreams of rodents that consume this type of poison and causing organ failure and death. The most common type of calcium releaser rat poison is vitamin D3, a safe option that carries no risk of secondary poisoning in the event that the rat is consumed by a predator, and therefore having a minimal ecological impact outside of the targeted rodents.
The final, and most common, type of rat poison contains anticoagulants. These cause internal bleeding when consumed, causing the rat to die slowly. These require a relatively high dosage in order to work, and often need the rat to consume several doses of poison in order to take effect.
In addition to this, the risk of collateral damage from anticoagulants is significant, as they are not specific to rodents in any way and can cause death in a wide range of smaller animals and other health problems in larger creatures.
What is in Rat Poison?
There are many different types of rat poison, but all of them are made from some sort of rodenticide and a delivery method to encourage the rats to consume the poison. These delivery methods include forms such as pellets, poisoned seeds, powders for mixing with water, or larger paraffin wax based blocks.
The three main types of rodenticide found in rat poison are calcium releasers, which cause organ failure, acute toxins, which build up levels of toxic substances in the bodies of the rats, and anticoagulants, which prevent vitamin K production and cause internal bleeding.
All of these are unpleasant substances, and most are not specific to rats, giving a high risk of secondary poisoning, ecological damage, and cross-contamination. As such, rat poison should only be used as a last resort when more humane options with less risk of collateral damage have been exhausted with no success.
How long Does Rat Poison take to kill a Rat?
The length of time it takes for rat poison to kill a rat depends on the size of the rat and the type and age of the poison, with older rat poisons that have been left in the cupboard for a while generally being less effective and taking longer to kill rats. In general, though, most rat poisons take an average of 2 to 3 days to kill a rat as long as it has eaten enough of the poison. 4 to 6 days is perhaps a more realistic expectation, as rats will not always eat enough of the poison for full efficacy.
In order to speed up the process of a rat’s death as far as possible, there are a number of steps you can take to encourage the rat to consume as much poison as possible. Placing the poison in the optimal position and making sure that you remove any spoiled poison as soon as possible can make a difference, as can removing all other potential food sources in order to direct the rats towards the poison.
It is also important to always put the poison in the same place, as most rodents are driven by familiarity and are much less likely to try to eat something unexpected that they do not recognize.
Many types of rat poison can cause secondary poisoning of predators and birds of prey that consume contaminated rats. Looking out for wildlife safe rat poisons can significantly reduce the ecological impact of your rat poisoning activities!
Decomposing dead rats can give off a powerful and unpleasant odor, so when using rat poison, it is important to find and dispose of the bodies as quickly as possible!
