An employee scratches his arm in a meeting. No one says anything, but it's on everyone's mind. What if it's bedbugs? The subject is taboo in the workplace, much more so than at home. And yet, a bedbug in the office is exactly the same insect as at home: it seeks blood, warmth and dark corners. The difference is that in a 40-person open space in Brussels, the spread can be lightning-fast.

Things to remember

• A pragmatic guide based on local Brussels expertise, distinguishing between the specificities of a tertiary infestation (IT equipment, open spaces) and a domestic infestation, to reassure employers and employees via an immediate action protocol.

• Managing return to work and prevention

We regularly intervene in offices in Brussels, and the observation is always the same: infestation in the workplace is detected too late. Employers play it down, employees don't dare talk about it, and in the meantime, bedbugs quietly colonize office chairs, electrical outlets and, yes, even laptops. This article is a practical guide for employers, HR managers and employees who want to understand the real risks, know the protocol to follow and, above all, act fast.

No unnecessary panic, no supermarket spray miracles. Let's talk about what really works.

Offices vs. homes: Identifying specific hiding places and real risks

In the home, bed bugs hide in mattresses, box springs and baseboards. It's a familiar sight. In the office, it's a different story. The hiding places for bed bugs in the office are more varied and more devious than you might imagine, because the environment is radically different.

Take a typical open space. You've got dozens of upholstered office chairs, drawer pedestals that are rarely thoroughly cleaned, cable ducts running everywhere, false ceilings with gaps. Every chair seam, every adjustable desk groove, every wall socket is a potential hiding place. And bedbugs love places that are never disturbed: the underside of a fixed desk, the back of a storage cupboard, the lockers in the checkroom.

The question is often asked: is it possible to have bedbugs in a laptop? The answer is a resounding yes. An adult bedbug is 5 to 7 mm long. Laptop vents, USB ports, the space between the keyboard and the chassis: that's all they need. We've already found nymphs in docking stations. A laptop that goes from home to the office is an ideal means of transport. The device is warm, it's handled daily, and it travels in a backpack or satchel, another ideal hiding place.

An important feature of workplace infestation is that bedbugs have no permanent source of food at night, since offices are empty. But that doesn't stop them from settling in. They can fast for several months, waiting for employees to return on Monday morning. And when someone sits on the same chair for eight hours a day, that's more than enough time for them to feed, even during the day. Bedbugs are mainly nocturnal, but when they're hungry, they adapt. This is regularly observed in the field.

There are many real risks for a company. The first is health: stings, allergic reactions, psychological stress for employees. The second is legal. In Belgium, employers have an obligation to guarantee a healthy working environment. The Code du bien-être au travail is clear on this point. Ignoring the problem means exposing yourself to complaints and liability. The third risk is reputational. An employee posting on social networks that his office is infested is a nightmare in terms of image.

A point that's often overlooked: meeting rooms. Sofas, reception chairs, curtains. These spaces are used by everyone, superficially cleaned and rarely inspected. It's a crossroads of propagation. The same goes for changing rooms and rest areas with benches. In short, bedbugs' hiding places in the office are wherever there's fabric, residual heat and relative darkness.

Confirmed infestation: Corporate protocol vs. ineffective DIY solutions

You've found a bedbug on an office chair. Or an employee is showing suspicious bites. First rule of thumb: don't improvise. Dealing with bedbugs in the workplace has nothing to do with what you do at home, and even less to do with the «tips» you find on the Internet.

Let's get straight to the point: over-the-counter insecticide sprays, lavender essential oils, baking soda sprinkled under desks - none of it works. Worse still, commercial sprays disperse bedbugs. They flee the treated area and colonize the office next door, the floor above, the break room. A localized problem becomes a generalized infestation. That's exactly what happens when you arrive after an attempt at home treatment.

The occupational health protocol in the event of confirmed infestation should follow these steps:

1. Immediate notification. Any employee or manager spotting signs (live insects, black marks on chair seams, molts, grouped bites) must alert management or the HR department. Not in three days. Now.

2. Professional inspection. Call in a specialist for canine detection in the office. A trained sniffer dog identifies outbreaks within minutes, with a reliability of over 95%. This is the quickest and most reliable method of delimiting the extent of infestation, especially in a large area.

3. Area insulation. The workstations concerned are condemned. Above all, don't move the furniture to another floor (this is the classic reflex, and the worst thing to do).

4. Professional treatment. Professional office disinsectisation in Brussels generally involves a combined treatment: thermal (dry steam at 180°C on furniture) and targeted chemical (residual insecticide applied by a certified technician). A minimum of two passes, spaced 10 to 15 days apart, to eliminate any eggs that may have hatched in the meantime.

5. Post-processing control. New canine detection 3 to 4 weeks after the last pass to confirm eradication.

A word about labor law and bedbugs. Employers can't pretend nothing's happened. The Belgian law on well-being at work requires action to be taken in the face of any identified risk to workers' health. An employee who reports an infestation and whose employer fails to react can turn to the prevention advisor, the CPPT (Comité pour la Prévention et la Protection au Travail - Committee for Prevention and Protection at Work) or, as a last resort, the Workplace Wellness Control. Bedbugs are not classified as a biological hazard in the strict sense of the term, but the bites and stress they generate are clearly occupational health issues.

The cost of office disinsectisation in Brussels depends on the surface area and level of infestation. For a 200 m² flat, you can expect to pay between 800 and 2,000 euros per pass. It's an investment, yes. But compare it to the cost of collective sick leave, stress-related turnover or legal action. It doesn't take long to do the math.

There's one thing we'd like to stress: bedbug treatment in the workplace must be carried out by a registered professional. Not by the usual cleaning service, however competent it may be for routine maintenance. These are two different professions.

Strategic recommendations: Managing return to work and prevention

72% of the office infestations we treat in Brussels have a domestic origin. An employee unknowingly brings bedbugs from home in his or her jacket, bag or computer. Going to work with bedbugs, most people don't even realize they're doing it. Bedbugs are tiny and discreet, and they don't necessarily bite everyone in the same way: some people don't react at all to the bites.

So what do you do when an employee discovers an infestation at home? Should he or she continue to come into the office? The answer isn't simple, but here's our recommendation: yes, temporary telecommuting is the best option whenever possible. Telecommuting in the event of bedbugs is not a punishment, but a common-sense measure to protect colleagues while the home is being treated. The employer should facilitate this transition without stigmatizing the employee concerned.

If telecommuting is not an option (some jobs are not suitable), here are the minimum precautions to take:

• The employee puts all his clothes in the tumble-dryer at 60°C minimum for 30 minutes before leaving for work. Heat kills bedbugs and their eggs.

• The bag used for the trip is a smooth bag (no fabric, no complex seams), ideally plastic, that can be inspected easily.

• The laptop remains at the office until the home is treated, or it is placed in an airtight bag between the two locations.

• The coat is stored in a closed plastic bag, not on the common coat rack.

For long-term prevention of office infestation, there are a few things you can do to make a real difference. First of all, raise team awareness. Not with a bland corporate e-mail, but with real communication: what a bedbug looks like, what the signs are, how to report without shame. Taboo is the number one enemy of early detection.

Secondly, include a regular inspection in your premises maintenance contract. Preventive dog detection once or twice a year costs a few hundred euros, and enables us to catch the beginnings of an infestation before it gets out of hand. We systematically recommend it to companies in Brussels that have already experienced an episode.

Furniture also plays a role. Fabric armchairs with deep seams are much more at risk than chairs with plastic shells. We're not saying to replace everything overnight, but when it comes to the next renewal, it's a criterion to be taken into account. Closed personal lockers rather than open coat racks, smooth storage rather than fabric boxes: every detail counts.

One last point, often overlooked: moving and furniture delivery companies. Second-hand furniture, boxes stored in a dubious warehouse, an armchair salvaged from another site - these are all risks. Inspect all new furniture before installing it. I mean it.

Preventing infestation in the office rests on three pillars: collective vigilance, regular inspection by professionals, and absolute responsiveness to the slightest report. With these three elements in place, the risk doesn't disappear, but it does become manageable.

Conclusion

Bedbugs in the office are neither a fatality nor an unmanageable catastrophe. It's a real problem that requires a professional and rapid response. The mistake is to wait, minimize or cobble together a home-made solution.

If you are an employer in Brussels and suspect an infestation, have your premises inspected by a professional. If you're an employee with bedbugs in your home, talk to your manager: you're protecting your colleagues as well as yourself. At Punaisesdelitbruxelles, we take offices, shops and professional spaces as seriously as we do private homes. One call, one inspection, one action plan. It's as simple as that.
