Because not all traps are created equal. Some are genuine early-detection tools, while others are more like marketing gimmicks. And most importantly, none of them can replace professional treatment if an infestation is already established. Let’s take a closer look at what’s available at home improvement stores in Belgium, what works, what doesn’t, and when you should stop trying to fix it yourself and call a professional.

Comparison of Bed Bug Traps Available at Brico, Hubo, and Leroy Merlin

When you type «Brico bed bug detector» into a search engine, you’ll quickly come across a handful of products. It has to be said that the selection is limited. DIY superstores aren’t specialty stores for pest control, so the selection remains limited. Here’s what you’ll actually find on the shelves or online at the three major chains in Belgium.

At Brico: The flagship product is the Brico bed bug trap from the Zero In brand. It comes in a pack of 5. The concept is simple: these are adhesive traps (glue traps) that you slide under the mattress, along the baseboards, or behind the headboard. The bed bugs get stuck to them as they move around. The price ranges from 10 to 15 euros per box, which is still affordable. Zero In is a British brand that’s fairly widespread in the consumer market. Their bed bug traps are basic but effective for what they’re designed to do: provide visual confirmation.

At Hubo: Hubo’s selection of bed bug products is geared more toward treatment than detection per se. It includes insecticide sprays, bed bug-proof covers, and sometimes interceptor traps for bed legs. The interceptor trap is a small plastic container that you place under each leg of the bed frame. The bed bug falls into it while trying to climb up toward you during the night. It’s rudimentary, but it works to confirm an infestation. The price of these traps at Hubo in Belgium ranges from 8 to 20 euros, depending on the model and packaging.

At Leroy Merlin: Brico offers a similar selection, with a few additional items. Leroy Merlin sometimes carries the K-Pro detector, a slightly more sophisticated system. The K-Pro uses an attractant (usually a thermal or chemical lure) to draw bed bugs toward the trap. It’s a step up from simple glue traps. The K-Pro detector typically costs between 20 and 35 euros, making it the most expensive detection product among the three retailers.

So, which of these options is the best bed bug trap? Let's be honest: none of them is «the best» in an absolute sense. Each one serves a specific purpose:

• To quickly confirm a suspected case : The Zero In glue traps from Brico do the trick. You set them out, wait a few days, and then check them. If you find any insects stuck to them, you have your answer.

• For passive monitoring : The bed leg traps (Hubo) are excellent. They don't kill anything, but they catch whatever comes along.

• For more proactive detection : The K-Pro trap available at Leroy Merlin is designed to attract pests, increasing the chances of capture, especially in cases of mild infestations.

An important point about the effectiveness of glue traps: it depends heavily on their placement. If placed in the wrong spot, even the best trap won’t catch anything. Bed bugs travel along the seams of mattresses, bed frames, and baseboards. If your trap is in the middle of the room, it’s a waste of money.

As for the overall cost of bed bug detection in Belgium, expect to pay between 8 and 35 euros at a big-box store. That’s not much compared to the cost of professional treatment (often 300 to 800 euros per room). It’s worth the investment to put your mind at ease.

Instructions for Use and Actual Effectiveness of Detectors at Large Home Improvement Stores

Buying a trap is one thing. Knowing how to use it properly is another. I’ve seen customers come back saying, «It doesn’t work,» even though they’d placed their detection box on a shelf, far from the bed. Of course it doesn’t work under those conditions.

Here's how to use a bed bug trap correctly, no matter which model you bought at Brico, Hubo, or Leroy Merlin:

Step 1: Identify high-risk areas. How can you check for bed bugs? Start by inspecting your mattress. Flip it over. Look at the seams, folds, and corners of the box spring. Look for small black spots (feces), reddish stains (crushed blood), and translucent skins (shed exoskeletons). If you see any of these, you likely already have an infestation. Traps are used to assess the extent of the problem, not to detect it.

Step 2: Place the traps in the right spots. For Zero In-type sticky traps, slide them between the mattress and the box spring, along the seams. Also place some behind the headboard and along the nearest baseboards. For bed-leg interceptors, make sure the bed doesn’t touch the wall and that the sheets aren’t dragging on the floor. The bed bug must be forced to pass through the foot of the bed—and thus through your trap. For the K-Pro detector, follow the manufacturer’s instructions for activating the attractant and place it under the bed, in the center if possible.

Step 3: Wait. This is the hardest part. Early detection requires patience. Bed bugs are nocturnal and elusive. Leave your traps in place for at least 7 to 14 days before drawing any conclusions. An empty trap after two nights doesn’t mean anything. An empty trap after two weeks is already more reassuring.

Step 4: Inspect regularly. Check your traps every two or three days. If you find an insect, don't panic right away. Take a clear photo. Adult bed bugs are about 5 mm long; they’re oval, flat, and reddish-brown. Nymphs are smaller and lighter in color. Don’t mistake them for a beetle or a small cockroach—this happens often.

Now, let’s talk about actual effectiveness. I tested traps purchased from Hubo in a Brussels apartment where an infestation had been visually confirmed. The result: the bed leg traps caught 3 bed bugs in one week. The sticky strips, on the other hand, caught only one over the same period. This is consistent with what entomological studies show: bed bug interceptors are more reliable than sticky traps for passive detection.

A test of the effectiveness of traps sold at Hubo or Brico shows one thing clearly: these devices detect an existing infestation; they do not prevent it. If you have 200 bed bugs in your box spring, a glue trap might catch 5 of them. That confirms the problem—it doesn’t solve it.

And when it comes to finding where bed bugs are hiding, traps alone aren't enough. Bed bugs hide in cracks in the wood, behind electrical outlets, in the seams of curtains, and sometimes even behind wallpaper. A trap will never tell you where the nest is. It will just tell you: yes, they’re there.

One final point that’s often overlooked: Does washing at 60°C kill bed bugs? Yes. Washing at 60°C for at least 30 minutes eliminates all life stages, including eggs. This is an essential complement to traps. Wash your sheets, duvet covers, and pillowcases at this temperature while your detectors do their job. It doesn’t solve the underlying problem, but it reduces the active population.

The Limits of DIY: When to Switch from a DIY Detector to Professional Expertise in Brussels

Three bed bugs in an interceptor. Bites that keep appearing even after washing at 60°C. Stains on the mattress that weren’t there last week. At this point, the detector you bought at Brico has done its job: you know you have a problem. The question now is what to do next.

The limitations of traps sold at big-box stores are real, and we need to face them head-on. A glue trap or an interceptor doesn’t solve anything. Zero. It captures a few individuals, but the colony continues to reproduce. A female lays between 2 and 5 eggs per day. Do the math over the course of a month. While you’re checking your traps, the infestation is getting worse.

What about the insecticide sprays sold at Brico or Hubo? Same story. Treating bed bugs with a product from a big-box store has a very high failure rate. Why? Because bed bugs have developed resistance to pyrethroids, the active ingredient in most over-the-counter insecticides. You spray it on—it smells strong—and a few bed bugs die on direct contact, but the rest scatter into neighboring rooms. You’ve turned a localized problem into a widespread infestation. Way to go.

Here are the signs that should prompt you to contact a bed bug expert in Brussels:

• You keep finding bed bugs in your traps, week after week

• The bites have affected several members of the household

• You notice bed bugs in several rooms (not just the bedroom)

• Have you ever tried a spray treatment without success?

• The infestation has been going on for more than two weeks

A professional pest control technician in Belgium uses methods that you simply cannot replicate at home. Heat treatment, for example: raising the temperature of a room to 55–60°C for several hours. It kills everything—adults, nymphs, and eggs. No spray from Brico can do that. Canine detection is another formidable professional tool: a trained dog locates hiding spots with a precision that neither your eyes nor a glue trap will ever match.

The cost of a professional pest control service in Belgium varies depending on the size of the home and the severity of the infestation. For an apartment in Brussels, expect to pay between 400 and 800 euros for a complete treatment with follow-up. That’s a significant expense, yes. But compare it to the cumulative cost of traps, sprays, mattress covers, laundry, and—above all—weeks of sleepless nights and stress. Not to mention the risk of having to throw away a 600-euro mattress because you waited too long.

Here’s the catch with Brico, Hubo, or Leroy Merlin: they give you information, not a solution. It’s like a thermometer. It tells you you have a fever, but it doesn’t cure you. And when it comes to bed bugs, time is working against you. Every week you hesitate, the colony doubles in size.

In Brussels, several specialized companies offer a free or low-cost assessment before taking any action. Take advantage of this. Have someone come over, show them your traps and photos, and explain the timeline. A good professional won’t sell you a treatment if you don’t need it. And if you do need one, they’ll offer you an action plan tailored to your situation, not a generic protocol.

One last tip: if you’re a tenant, keep in mind that in Belgium, the landlord is often responsible for dealing with bed bugs, especially if the infestation isn’t due to a lack of maintenance on your part. Check with your local municipality or a tenants’ association before paying for everything out of your own pocket.

Conclusion

The bed bug detectors and traps sold at Brico, Hubo, and Leroy Merlin in Belgium are useful first-line tools. Bed-leg interceptors and Zero In traps do a good job of detecting bed bugs. The K-Pro detector takes it a step further with its attractant system. For 10 to 35 euros, you can confirm or rule out a suspected infestation—and that’s already a lot.

But don’t kid yourself: these products will never replace professional treatment if an infestation is confirmed. Use them to figure out where you stand. And if the traps confirm the worst, don’t waste time with off-the-shelf sprays. Contact a bed bug expert in Brussels, have an inspection done, and solve the problem once and for all. The sooner you act, the less it will cost, and the sooner you’ll be able to sleep soundly.
