Have you seen droppings, heard wall scrabbling, or tiny paw marks by your house? Are you experiencing a pest issue but not sure if you have rats or mice? And most importantly—will the rat trap actually catch mice? These are the things we frequently get asked at TopGrid, and we’re here to put you straight. As a reliable pest control firm in Malaysia operating out of Subang Jaya, we’ve had years of experience dealing with all manner of pest problems—from big, violent rats to fast, stealthy mice. Here’s the lowdown on what you should know before you set that trap.
Rats and Mice Are Different Rodents
While rats and mice belong to the rodent family, they have different sizes, behaviors, and habits. A standard rat can weigh several times more than a typical mouse, and that alone affects how traps are designed. Mice are lightweight and quick, while rats are heavier and often more cautious. This difference matters because most rat traps are built to detect the weight and force of a larger rodent. That means a mouse may not even trigger the trap—or worse, it may escape with the bait.
Rat Traps May Not Be Sensitive Enough
The spring mechanism in a typical rat trap requires more pressure to activate. Since mice are smaller and weigh less, they may walk right over the trigger plate without setting it off. In many cases, we’ve seen mice eat the bait and leave before the trap activates. This is why mouse-specific traps are designed with lighter trigger sensitivity and smaller entryways, which are better suited to their size and behavior.
Here’s Where Most Mistakes Happen
Many homeowners, when trying to handle pest control in Malaysia on their own, unknowingly make small mistakes that allow rodents to thrive longer than expected. Here are the most common errors we’ve seen:
- Using the wrong trap for the wrong rodent
- Placing traps in open areas where mice don’t travel
- Relying on bait without considering rodent behavior
- Ignoring signs of both rat and mouse presence
Rodents Choose Their Paths Carefully
What we’ve learned from years of providing pest control services in Subang Jaya is that both rats and mice are creatures of habit. Mice tend to explore more but stick close to walls and narrow spaces. Rats usually follow set paths and avoid open, exposed areas. Trap placement needs to reflect those habits to be effective.
The Wrong Trap Wastes Time
Using a rat trap for a mouse infestation is not just ineffective—it often delays the proper response. As the pest control company in Malaysia, we’ve seen infestations worsen simply because the traps didn’t match the rodent. By the time the issue is identified, the rodents have had more time to spread and cause damage.
Choosing the Right Method Matters
Whether it’s a house, shop, or warehouse, the success of any pest control method depends on accurate identification of the rodent type. We’ve worked in places where both rats and mice are present, and each required different strategy. One-size-fits-all doesn’t work when it comes to exterminating services—especially with smart, adaptive pests.
What to Consider Before Setting a Trap
Before deciding what trap to use, it helps to look at a few simple signs that might point to either mice or rats. Here’s what we usually observe:
- Size of droppings: smaller for mice, larger for rats
- Noise: mice are quieter, rats make more noticeable sounds
- Chew marks: finer and scattered with mice, stronger with rats
- Nesting materials: mice use soft, shredded materials, rats use heavier debris

FAQs
Rat traps often don’t work quickly on mice because they’re not designed for smaller rodents. Mice may avoid or fail to trigger them, making pest control efforts less effective without proper tools. Many pest control companies in Malaysia use mouse-specific traps for faster results.
Yes, rat traps are larger and require more pressure to trigger, while mouse traps are smaller and more sensitive to light weight. Using the wrong trap can delay results, especially in pest control situations involving mice. Proper equipment choice is key for effective pest exterminators in Malaysia.
The fastest way to get rid of mice is targeted trapping using the right-sized tools combined with sealing entry points. Many pest control services in Subang Jaya include a full inspection to identify hiding spots and apply precise trapping. This method is widely used in pest control in Malaysia for efficient results.
Some rat baits can work on mice, but dosage and formulation aren’t always effective due to size and feeding habits. It’s common in pest control services to use bait specifically made for each rodent type to avoid resistance or failure. A professional pest exterminator in Malaysia will always assess bait compatibility.
Trapping mice is often more effective in small indoor infestations, while baiting is used for larger or hidden populations. The best pest control in Malaysia usually combines both, depending on the level of the pest issue. The strategy should be tailored to rodent behavior and the environment.
Rats may leave if food and water sources are removed, but not immediately. As persistent pests, they can survive on scraps and search for wider areas. Many pest control companies in Malaysia recommend combining food control with physical exclusion and traps.
Snap traps designed for mice are among the quickest methods for killing them. These are commonly used in pest control services in Subang Jaya for fast results when dealing with light infestations. Proper placement and bait selection increase effectiveness.
Mice may disappear due to environmental changes, reduced food supply, or predator presence. However, without proper pest control, they often return. It’s common for pest control companies in Malaysia to monitor for re-entry points and ensure complete elimination.
Mice are known to avoid strong smells like peppermint oil, clove, and ammonia. While not foolproof, these can help reduce rodent activity when used alongside proper pest measures. They are sometimes used as part of natural deterrents by homeowners before calling pest control in Malaysia.
Vinegar has a strong smell that may discourage mice temporarily, but it is not a long-term solution. For serious pest problems, this method is rarely effective on its own. Pest control services in Subang Jaya usually recommend sealing entry points and using traps instead.
Commercial ultrasonic repellents and concentrated peppermint-based sprays are among the strongest non-toxic mouse deterrents. Still, these are rarely enough alone for serious rodent infestations. Most pest exterminators in Malaysia teams pair repellents with traps for lasting impact.
Steel wool in entry points and a mixture of baking soda and bait are common home remedies. While these may help, they are not always reliable without professional pest assessment. Many in pest control in Malaysia recommend using remedies only as short-term support.
Mothballs may repel mice due to their strong odor, but they’re not a guaranteed solution and pose health risks. Their use is discouraged by most pest control companies in Malaysia for indoor environments. Safer and more effective alternatives are available for rodent control.
Chilli powder can irritate mice, but it’s not a consistent deterrent for infestations. It’s sometimes used in DIY methods, but the best pest control in Malaysia relies on more effective strategies. For long-term results, professional intervention is usually required.
