Imagine spending your nights locked up in a nine-square-meter space, sometimes with two other people, with insects that come out as soon as the lights go out to feed on your blood. This isn’t a horror movie scenario. It’s the daily reality for hundreds of inmates in Belgian prisons.

Visit bed bugs in prison These are not isolated incidents. We’re talking about a structural problem that affects multiple cells, multiple wings, and sometimes entire facilities. And in a closed environment, where you can’t change rooms or throw away your mattress whenever you want, the situation quickly becomes unmanageable.

At Punaisesdelitbruxelles, we deal with severe infestations every week. We’re familiar with closed communities. So when we look at what’s happening behind bars in 2026, we can immediately see why things are spiraling out of control. This article takes stock of the situation: the true scale of the problem, its root causes, and why current protocols aren’t enough.

The Proliferation of Bed Bugs in Belgian Prisons: An Overview

«I hardly sleep at night anymore.» We hear this phrase not only from inmates but also from their loved ones during visiting hours. It alone sums up what life has become in some Belgian prison cells.

L’Pest infestation in a Belgian prison is no longer just a minor issue. Berkendael Prison in Brussels has been the subject of repeated reports regarding the bed bugs. At the Tournai prison, the general conditions—unsanitary conditions, dampness, dilapidation, and pests—are regularly cited in reports and union alerts. These two facilities are not exceptions: they are symptomatic of a system under strain.

What is striking is the speed of propagation. The Cimex lectularius, the common bed bug, does not fly or jump. It moves around on foot, discreetly, and is carried from one cell to another via clothing, sheets, mattresses, or even documents that are passed from person to person. In a building where everything is shared and where people are constantly coming and going, an infestation quickly becomes a collective problem.

Is it a big deal to find a bed bug? In prison, yes, definitely. Because a single fertilized female can lay between 200 and 500 eggs in her lifetime. In a heated environment, without the possibility of quick and effective treatment, the population explodes within a few weeks. What starts as a single bed bug can quickly turn into a colony of several hundred hiding in cracks in the walls, mattress seams, and behind baseboards.

Reports from the field describe inmates covered in bites, mattresses that are turned over to reveal swarms of insects, and cells that must be temporarily closed. Some accounts even mention inmates refusing to return to a cell because the infestation is so obvious. The inmates' health is directly at stake—and not just their comfort. We'll come back to this, but for now, just keep this in mind: when a prison infestation The fact that it has reached this stage means that the problem has been around for a long time.

The Main Causes of Mass Infestation in Closed Prisons

Why is prison an ideal habitat for these insects? Because all the favorable conditions come together in one place at the same time.

The first one is the prison overcrowding. Belgium regularly exceeds an occupancy rate of 120 % in several of its prisons. In practice, cells designed for one person house two or three, with mattresses laid directly on the floor. The more warm bodies there are in a confined space, the more food sources bed bugs have available. And the more the insect spread It happens quickly, because every new inmate, every transfer, and every return from furlough can bring a bedbug back in their belongings.

The second factor is the condition of the buildings. Many Belgian establishments are dilapidated, with cracked walls, peeling baseboards, and old furniture—all of which make for perfect hiding spots. Bed bugs love dark, narrow nooks and crannies, right next to their prey. Add to that the’cell dysfunction, where maintaining hygiene is difficult due to a lack of resources and cleaning supplies, and you end up with a shelter tailor-made for Cimex lectularius.

Third, and by no means least: constant movement. A prison is a continuous flow of activity. New arrivals, transfers between facilities, trips to and from court, the communal laundry room. Every movement is an opportunity for insects to spread. An inmate transferred from Berkendael to another facility can unwittingly bring the problem with them. This is exactly why partial treatment is useless: if you treat one cell for pests but leave the neighboring ones infested, the whole thing starts all over again in a matter of days.

We also need to address the issue of failure to report. Is it mandatory to report the presence of bed bugs? In the civilian sector, tenants and landlords have clear obligations. In prison, the reporting chain is less defined and often too slow. Some inmates do not report infestations out of fear, resignation, or because they believe it won’t make a difference. As a result, the infestation spreads unnoticed before any action is taken. This delay alone turns a manageable outbreak into a public health disaster.

Control Protocols and Limitations of Current Interventions in Prisons

On paper, there are procedures. In reality, they run into obstacles that make the pest control in prisons much less effective than it should be.

The number one problem is using chemical treatment in isolation. All too often, people spray an insecticide in a room and consider the matter settled. But bed bugs have been developing resistance to pyrethroids for years. A poorly targeted spray kills only part of the colony and drives the survivors to move, thereby colonizing other rooms. This makes the problem worse instead of solving it.

Visit bed bug treatment An effective treatment relies on a combined approach. First, heat: a heat treatment that raises the temperature of the affected areas above 55 °C destroys insects and eggs at all life stages, leaving them with no chance of survival. This is the preferred method in the field when the infestation is severe. We supplement this with diatomaceous earth in hard-to-reach areas, treatment of bed frames and furniture, and rigorous follow-up at two and four weeks. Without this follow-up, we’ll miss the larvae that hatch after the first treatment.

In a prison setting, implementing this protocol is a real challenge. You have to clear the cell, relocate the inmates, coordinate security teams, and secure the surrounding areas all at the same time. With the overpopulation, where should the residents be relocated? A lack of resources and staff is holding everything up. A professional pest control Any project worthy of the name requires time, space, and a budget—three things that are sorely lacking.

L’hygiene in prison raises the fundamental question: Are bed bugs dangerous to humans? It’s true that they don’t transmit diseases. But sleeping with bed bugs, night after night, is never harmless: repeated bites, itching, chronic insomnia, anxiety, and sometimes secondary skin infections from excessive scratching. For people already psychologically vulnerable due to incarceration, the impact on mental health is very real. In the United States, an inmate died in his cell after being devoured by insects. This is an extreme case, but it shows just how far neglect of health care can lead.

What’s needed? A clear, mandatory protocol that addresses entire blocks rather than isolated cells, systematic reporting starting with the very first puncture, and the use of professionals trained in heat treatment. This isn’t science fiction. It’s what we do every day in civilian communities.

Conclusion

The presence of bed bugs in prisons The Belgian situation is not inevitable; it is the result of a system that has reached its limits: overcrowding, dilapidated buildings, and inadequate protocols. As long as we continue to treat one cell at a time with outdated insecticides, we will only be shifting the problem elsewhere. The solution exists; it involves a comprehensive, thermal, and ongoing approach carried out by competent professionals.

Are you a relative of an inmate, a prison staff member, or an attorney dealing with a bed bug infestation? Don’t let the problem get out of hand. Document it, report it, and demand serious action. And if you need an expert opinion on a bed bug infestation—whether in a communal setting or in your home—the team at Punaisesdelitbruxelles is here to advise you and take effective action. Because with a bed bug problem, the longer you wait, the more it costs—both in money and in health.
