That is why Janssen Pest Control offers fast and discreet control of cockroaches. cockroach control netherlands with proven methods that eliminate the entire colony.

Why cockroaches are so dangerous

Cockroaches are carriers of more than 30 types of bacteria, including salmonella, E. coli and listeria. This is because they walk through sewers, rubbish and other contaminated places, then leave these germs on food, kitchen worktops and eating utensils. Moreover, their faeces and shedding skin cause asthma and allergy symptoms, especially in children. These health risks make professional cockroach control netherlands absolutely necessary.

Fast Propagation Requires Fast Action

A female cockroach produces 10-40 egg capsules in her lifetime, each containing 10-50 eggs. This means that one cockroach can result in hundreds of offspring within a few months. In addition, cockroaches are nocturnal and hide during the day, so you often don't notice a problem until a heavy infestation occurs. Quick action at the first sighting is therefore crucial.

Why Choose Our Cockroach Control?

At cockroach control netherlands speed and hygiene are essential. This is why Janssen Pest Control distinguishes itself in several areas:

Specialised Catering Expert

We are specialists in cockroach control for catering establishments, kitchens and food companies. This is because our exterminators know all HACCP guidelines and work to the highest hygiene standards. Moreover, we work quickly and discreetly to minimise business interruption. This expertise also benefits private individuals.

Discreet Gel Treatment: The Most Effective Method

Our primary method is professional gel treatment. This method works extremely effectively because cockroaches eat the gel and then die. In addition, other cockroaches eat the carcasses, creating a chain reaction that eliminates the entire colony. The gel is strategically applied to walkways and hiding places, completely invisible to customers and guests.

Additional spray treatment for heavy pests

For very heavy infestations, we combine gel treatment with professional spray treatment. Residual insecticides are applied in all hiding places: behind equipment, in cracks, under cabinets and in technical areas. This double approach guarantees complete elimination, even in large colonies.

Focus on Hygiene and Restraint

Cockroach control goes beyond just killing the cockroaches. We therefore advise extensively on hygiene measures and structural adjustments to prevent recurrence. These include sealing gaps, adapting waste storage and optimising cleaning procedures. This preventive approach prevents new infestations.

NVWA-Proof Reporting

For catering establishments and food companies, we provide detailed treatment reports that comply with NVWA requirements. These reports include all work carried out, resources used and follow-up recommendations. This demonstrates that you act appropriately in cockroach problems.

Our Approach: From Cockroach infestation to Cockroach-free

We use a proven method at cockroach control netherlands which ensures fast and lasting results:

Step 1: Inspection and Species Determination

Our specialist carries out a thorough inspection to identify the cockroach species. Two species mainly occur in the Netherlands: the German cockroach (small, light brown, mainly in kitchens) and the Oriental cockroach (larger, dark, mainly in basements and bathrooms). This determination is important because each species exhibits different behaviour. We also locate all hiding places: behind refrigerators, under sinks, in motors of appliances, in cracks and seams.

Step 2: Strategic Gel Treatment

We apply professional bait gel on all walking routes and near hiding places. The gel is applied in small drops at strategic points: behind equipment, in cracks along walls, under cupboards and near water sources. Cockroaches are in fact attracted to the gel, eat from it and die within 24-48 hours. They are then eaten by other cockroaches, causing a chain reaction.

Step 3: Spray Treatment (If Needed)

For heavy infestations, we add a spray treatment with residual insecticides. These agents remain effective for weeks and kill cockroaches that come into contact with them. We spray into all cracks, seams and hiding places that are difficult to reach with gel. We also treat walkways and access points to stop new cockroaches from entering.

Step 4: Restraint and hygiene advice

We inspect your premises for entry points and structural problems. Cockroaches often enter through: drains, cracks under doors, cracks in walls, supplied product packaging and through pipes. Therefore, we advise on sealing these access points. In addition, we provide comprehensive hygiene advice: food and waste storage, cleaning procedures and preventive measures.

Step 5: Post-treatment and monitoring

After 2-4 weeks, we return for a control visit. We inspect whether all cockroaches have been eliminated and refresh the bait gel if necessary. During this visit, newly hatched eggs are also eliminated (as eggs are resistant to the initial treatment). In addition, we place monitoring traps to detect any remaining activity. Upon complete elimination, you will receive a final report with prevention advice.

Frequently asked questions about Cockroach Control Netherlands

Do you have questions about cockroach control? Below are answers to the most frequently asked questions. Is your question not listed? Feel free to contact with us.

We understand that cockroaches require urgency, especially in hospitality and food establishments. Therefore, we aim to be on site within 24 hours. For emergencies (e.g. NVWA inspection), we can often be there within 4 hours for an emergency surcharge. Call our emergency line for the fastest service.
Yes, cockroaches pose a serious health risk. They carry more than 30 types of bacteria including salmonella, E. coli and listeria. Moreover, their faeces and molting skins cause asthma and allergies, especially in children. Therefore, prompt professional control is important for your health and hygiene.
With gel treatment, you usually see results within 3-7 days. However, complete elimination requires 2-4 weeks as the eggs are resistant to the initial treatment. Therefore, we always schedule a post-treatment after 2-3 weeks to eliminate newly hatched cockroaches. Heavy infestations may require a third treatment.
The German cockroach is small (12-15mm), light brown and lives mainly in warm, dry kitchens. It therefore reproduces rapidly (6-8 generations per year). The Oriental cockroach is larger (20-25mm), dark and prefers cool, damp spaces such as basements and bathrooms. However, both require professional control for complete elimination.
No, contact sprays only kill cockroaches that are directly hit. However, they do not reach the colony in shelters and leave no residue. Moreover, sprays often cause cockroaches to flee to other rooms, spreading the problem. Professional gel treatment, on the other hand, is actively sought out by cockroaches and causes a chain reaction that eliminates the entire colony.
