Mouse Trap Bait Buying Guide

Even though most of the mouse trap baits we talked about can do a fairly good job at killing rodents by themselves, you still want to employ a more complex trap for the job. In this respect, some of the most effective mouse baits can serve a double-action purpose, which is part of the reason why they’re so popular, to begin with. Even so, they cannot all be expected to be just as effective, as some are definitely better than others. Not just better in the sense that they are more effective, but also due to being safer to use overall. Here are a few things you need to understand in order to ensure that your traps achieve the desired effect.

Understanding The Pests

The first thing you want to do in order to effectively remove pests of any kind is to take the steps to understand them better. We say this because most mice and rats have extraordinary vision, hearing, and an advanced sense of smell. This makes the little pests quite difficult to trap and even harder to remove on a permanent basis. So even though it may seem silly for some to even consider the mice’s intelligence, we assure you that it is the main reason why these little pests thrive in the first place. It is for this reason that you must take the necessary steps to ensure that the trap is well set and that it isn’t too obvious, as some mice are likely to avoid any source of food that is too far outside their comfort zone.

Different Bait For Different Rodents

Another thing you have to do is to figure out precisely what type of pest you are dealing with. The reason we say this is because different rodents react differently to any type of bait or trap you might have set up for them. For the most part, mice will try to take the bait away from the trap whereas rats are more likely to eat it then and there. So in the event of a mouse or rat stealing the bait away, you might want to invest in a poisonous bait that also has the capacity to kill the rodents by itself. Luckily for you, the market has a wide selection of such baits to choose from, each with its own characteristics.

How Does It Work?

Most of the bait types you can get nowadays employ some sort of rodenticide to help kill the rodents despite how effective the trap may or may not be. These powerful baits are formulated to attack the nervous system of the mouse or rat, causing death within just a couple of days after its ingestion. Furthermore, some of these baits can even kill the mouse if it simply touches the bait, nevermind eating it. As you would imagine, these are the type of baits that you want to squeeze in places only mice and/or rats will reach, so as to avoid them getting eaten by your pets.

The Space Issue

As you may already know, mice and rats can squeeze into incredibly tight spots in their quest for food. In a pinch, some can even chew their way through the walls, mainly through any exposed or vulnerable areas at the bottom of the walls. As a matter of fact, they can even live inside walls over extended periods of time, setting up little borrows in the process. It is for this reason that you want to deploy the mouse traps in areas that normally only mice would reach because chances are that they’re already doing it. Keep in mind that you don’t actually have to see them to know that they’re there, all you have to do is look for any droppings or signs of recent damage to the floor/walls.

Consider The Smell

Bear in mind that mice have an excellent sense of smell for the most part, which is why you want to employ bait that has a strong fragrance. If you can, look for mouse trap bait with a strong smell,
which is usually the type of bait based on protein or high in fat. Alternatively, look for baits with a sweetener because most mice and rats have quite a sweet tooth for anything that involves sugar. If not, then at least consider a bait that features any other form of smell likely to attract the interest of any rodents.


In their sudden desire to get rid of whatever pests bother them, people will sometimes make mistakes when setting up the traps. You see, you might have to experiment with a different type of trap if whatever trap you already use isn’t working. This is because, like we said, mice and rats are surprisingly intelligent, meaning that they might be able to learn when it’s best to stay away from certain types of food that is too much outside their comfort zone. This is precisely why it’s important to deploy the traps in areas where the mice/rats pass through, as they are likely to eventually take a bite out of sheer curiosity.

Setting Up The Trap

Not many people fully understand the importance of setting up a proper trap. They seem to think that just placing the trap on the floor is enough to catch a crafty mouse or rat, but in reality, the process is a little more intricate. What you want is to set up the traps in the same localized area, so as to create a specific system or a pattern of sorts. Go as close as you can to the high traffic areas of the room, the places mice and rats are most likely to roam through. If you can, go close to the location you suspect that they are using as a nest or a colony.

Using A Good Trap

Before you go looking for a complex trap, you must first figure out what type of bait to use it with. Fortunately for you, the market has quite a wide selection of traps and mouse trap baits to choose from. You can nowadays find pet-safe bait that even though it is formulated to be highly toxic for rodents, is rather safe for your dog or cat. Then again, if you’re not using the right trap, chances are that a good bait won’t do you much good anyway.
