What Is The Best Thing To Put In A Trap To Catch A Rat?
One of the more popular questions we get asked is what is the most effective bait for a rat?
To understand how to trap rats, we must first understand their behaviour. Due to their reputation as vermin, we often underestimate their intelligence and fortitude.
Rat Behaviours
Rats are neophobic, meaning they have an innate fear of anything new or unknown. This phobia applies to all aspects of their daily routine, including feeding habits. Such a phobia makes trapping more difficult; results require patience and perseverance.
The rat’s sense of smell is critical to its survival. Not only will they use this highly developed sense to identify mates and detect predators, but they can also use smell to determine whether food is safe to eat. Within a colony of rats, if some have fed on poison and become ill or passed away, other rats can determine the smell of the harmful substance and will then avoid it.
So, does this mean you can’t introduce rats to a new food source? Absolutely not. Rats are highly intelligent beings and have developed complex social structures which they utilise to investigate new food offerings. Within rat colonies are social tiers and rankings; an alpha rat will send subordinate rats to investigate a new food source to assess whether it is harmful. If multiple rats successfully feed, then the alphas will investigate themselves. Later in this blog, we will explain how to overcome this when trapping.
It’s essential to get rats feeding confidently in your trapping area. Imagine you or I were looking out into the garden one day, only to be greeted by a large hamper filled with exotic, expensive food with no hint as to who the generous gift provider was. We wouldn’t go racing out to indulge ourselves; instead, we would be suspicious and investigate how the parcel arrived and whether it’s safe to eat.
Pre-feeding And Parallel Feeding Are Essential
Pre-feeding the intended trapping area will encourage the rats to feed and build confidence. Parallel feeding is the same principle as pre-feeding. However, it’s offering free food once the trap is in position. It has the same purpose: to increase confidence and the illusion of a safe feeding area. With the social hierarchy in mind, the more rats that return home safely, the more likely it is that other rats will be encouraged to feed. Rats will then begin to feel safe to enter the trap. Whilst this may create the concern that dispatched rats will put off others entering the trap, the combination of the ‘safe’ food offering and the trap food offering means rats can’t distinguish that the trap is dispatching them. The sight of dispatched rodents does not put off rats; often, the first animal to eat a dead rat is another rat. It’s a little-known fact that rats are cannibals. For instance, if you used the Goodnature Chocolate Lure Pouch alongside your trap, you would resist the temptation to set up the trap on day 1 and follow the below steps instead:
Mix the chocolate lure with some oats (to make it go further!) and apply small amounts to the area where you wish to place the trap.
If you want to catch a rat fast and are willing to put in the extra effort; apply the feed to all areas where you have seen rats or suspect they are inhabiting. This means the rats are coming across the bait on a regular basis allowing your trap to camouflage in with the existing food sources once placed.
Whilst this article is focused the best bait for a rat trap, trap placement is also worth a mention. Your trap should be placed closest to where the rats are living, not where they are feeding. This means that the rats have less ground to cover to reach a food source, resulting in less exposure to predators and an increased sense of security.
Make A Lure/bait Which Closely Reflects ‘Safe’ Food Sources Within The Existing Habitat
The best homemade rat bait will reflect food sources readily available to the rats in your area. Incorporating these food types is a great way to encourage trap interaction and improve efficacy, as the bait will seem safe and familiar. This will make a ‘foreign’ object feel safer and encourage trap engagement. Some specific examples are below:
Stored grain and other cereals, such as muesli, can be included in the lure to keep the bait as natural as possible. Adding sunflower oil will allow you to adjust the viscosity.
Include the boilies and pellets anglers use within the lure; this food sustains the rats and won’t raise alarm bells. A Goodnature Long-life Meat Lovers pouch could be added to allow for adjustments in viscosity whilst reflecting the meat-based baits used around the lake.
.
Include the chicken feed within your lure, as this is the food item which has attracted the rats in the first place. The addition of other cereals such as muesli keeps the bait as natural as possible. Adding sunflower oil will allow you to adjust the viscosity, suet is another natural ingredient that attracts a rat to a trap.
Should you wish to use a Goodnature Trap, our lure basket is a great tool for applying home-made bait. Sticking to these rules will ensure you create an irresistible rat bait!
The Best Bait For Catching Rats Inside
Determining which food is irresistible to rats inside the home can be trickier and may require a ‘trial and error’ approach. The first thing to check is whether there are any exposed food sources within your house, such as muesli in the larder or open bags of food in cupboards. If this is the case, you must put these foods in sealed containers to limit access. If you find that rats or mice have been taking food, create a bait incorporating the food that rats or mice have been eating. If you have completed a thorough check of your home and have yet to find any obvious food sources, then you must adopt a trial-and-error method. A good starting place is chocolate lures or nut-based offerings. If you are trapping in multiple areas of the home, use different lures in each trap to compare results. Keep in mind that rats are neophobic, so ensure you give each lure a good couple of weeks trial before changing the flavour.
Final Word
There is no best bait for rats; trapping them takes perseverance. Now that you understand more about the behaviours and principles of lure selection, you should be well on your way.


After a while, my A24 trap went wrong, I phoned Goodnature and a new trap arrived, free of charge, the next day; what excellent service.
I have had an infestation of mice, which were duly cleared over an extended period of time. I found a pile of ten mice at the bottom of the gas trap, which was placed behind a broken pot stand. A few weeks later I found that the heaviest rats I have ever seen outside of Africa, brazingly walking around the garden. I have managed to all but eradicate the new residents, with the exception of what I think to be , a heavy footed rodent who has made the attic his new residence, I have heard him at night , moving across the floor of the attic, climbing down the pipework of the house, I’ve managed to eventually place , a goodnature a24 under the hot tank , where all the activity is taking place, he feels quite free to roam around the entire house, up and down the wall cavities, which provides easy access to 5 houses ,in a row ,pictures to follow,
