Worldwide there are some 64 species of rat (rattus). Of those, the 2 most common are the brown rat, also known as the Norway rat (Rattus norvegicus), and the black rat (Rattus rattus). The black rat is relatively rare, preferring to live in grain silos and warehouses around port areas. The brown rat is the one that lives in sewers, gardens, derelict buildings, and your home if it gets the chance. There is also a rumor that the brown rat is developing some kind of super-intellect. Which prompts the question ‘do rats learn to avoid traps?
In this post, we take a look at the question, and what you can do about it. As a pre-warning…. it will take time and patience! But you will get there…
Do rats learn to avoid traps?
The short answer is, and you are not going to like this, yes. Rats do learn to avoid traps. But not because they have developed some super trap-avoiding sixth sense. In fact, in all these attention-grabbing headlines about the rat population ‘booming’, there is an element of truth.
All animals, including the human species, live with the five senses of sight, hearing, taste, touch, and smell. As a human, our most acute sense is sight. We can see colors and shapes. In animals, other senses have been highly developed to ensure their survival.
Many animals have an acute sense of hearing, far greater than ours. Others have a sense of smell that can pick up the scent of food or foe often miles away.
Rats are generally considered nocturnal, but can often be seen in derelict, run-down areas, scavenging for food amongst uncollected waste during daylight.
Just like the fox, the rat’s fear of humans has begun to diminish.
However, just like most animals, (and many humans), rats suffer neophobia, (a fear of new). They tend to follow the same path from nest to a food source, and back again. And when moving on to unexplored territory, they try to avoid anything out of the ordinary, are cautious, and very wary. It is this wariness, in combination with its high level of intelligence, which makes the rat a lot more difficult to trap when compared to mice.
The sheer fact that the trap is new, and smells of you means the rat will try to avoid it as best as it can.
When it comes to successfully trapping ratty, patience and sneakiness will win the day.
What you can do to stop rats avoiding traps.
Of course, unless you’ve actually seen your visitor, it could be a rat or a mouse. The second and biggest giveaway, to tell if you are being invaded by one or the other, is the size of droppings. Rat droppings are a lot larger than mouse dropping, around the size of a rice grain.
Before we get started, this process may take a few days. You should use this time to order some rubber gloves because you will need them when handling the trap.
1. Find the location
You don’t have to find exactly where the rat is living. But the runs it uses going back and forth for food.
Rats will normally run close to solid structures. You should always set your rat traps up against a solid structure, like a wall. The rat is most likely to smell the rat bait and may investigate further as it is on the way!
They also poo around 40 times each night and leave grease marks from their fur and tail on walls, solid fixtures, and furniture. Careful inspection of these areas in kitchens, laundry rooms, outhouses, and sheds should reveal the rat’s regular route.
Stalk the rat!
2. The sneaky bit – give a false sense of security
As previously mentioned rats are extremely wary of anything new in their territory or along their runs, so patience is the name of the game. There are a number of different rat traps available, from the spring trap (for quick execution) to humane traps to release the animal back into the wild.
Whatever type of trap or poison you intend to use, make sure it can’t be reached by children or family pets.
Brown rats eat pretty much everything from raw meats, to chocolate, to cereals and nuts, to fruit and veg.
Give it a couple of days before checking to see if the rat bait has been taken. If not, remove the old and add fresh, or you may need to try different food as rat bait. If it has gone, don’t set the trap, just add more food.
The idea is to provide ratty with a false sense of security.
3. Spring the trap
With the rat taking the bait on a nightly basis, the next step is for you to set the trap. Don’t forget to add the bait BEFORE setting the rat trap.
Wear rubber gloves when setting the trap! The last thing you want is your scent all over the trap that the rat is now very familiar with.
Provided everything appears normal to the rat, you should have a cadaver to get rid of in the morning.
4. What happens if nothing happens?
If, after a week, your rat trap food remains untouched, you could be up against an Alpha rat. One that has seen it (and avoided it), all before. Here are some further steps you can take if you are actively engaging in warfare with a clever rat!
- Scout the rat run for more places to put a rat trap
- Add more rat traps
- Change the trap type
- Leave the traps alone for longer periods of time to reduce your scent
- Scatter more food around the trap to build confidence
It is also worth disguising the trap! You can place it inside a cardboard or wooden box painted the same color as the surroundings. Cut out an entrance and exit at each end. With the unset trap in the box, start the baiting process all over again.
Patience, as they say, is a virtue. This is especially true when dealing with a rat who is avoiding your traps!
Frequently Asked Questions
No, not really. They are not smart enough, but they have a natural fear of anything new or anything that doesn’t smell quite right. For this reason, you should always wear gloves so you do not get your own scent on the rat traps!
First, you must learn how the rat is operating. Where does it go? How does it travel? You should use this knowledge to trap the rat. Also, make sure you wear gloves when handling the traps! Oh, and make sure that you scatter some rat bait around the area of the trap too, that has worked for me in the past.
Rats do learn to avoid traps, there is no doubt about that. It is not because the rat recognizes it as a ‘trap’. The rat is likely to be voiding your trap because it is new, or it smells of you.
I always keep rat traps in my attic all year. I use bait that has a long shelf life such as nuts. That way, I do not have to go and check the traps very often, and because they have been in place for months/years, they smell the same as their surroundings.
Catching a rat that is avoiding your trap is frustrating, but you can beat it! You have a brain much bigger than theirs, remember that. You need to learn the rats behavior and movement. Only then will you catch the rat!
