Cockroach control for your home
Cockroaches at home? Eversor identifies the species, locates hiding places and carries out targeted treatment. Our experienced technicians check the outcome; Eversor remains your point of contact for questions and follow-up.
Identification
How can you identify cockroaches at home?
Cockroaches have a flat, oval body, six legs and long antennae. Young insects do not yet have fully developed wings. Also look for egg cases, shed skins and dark specks near hiding places.[1][4]
German cockroach
An adult is approximately 11–15 mm long, excluding antennae. This photo shows two dark lengthwise stripes directly behind the head.[8]
Brown-banded cockroach
This young brown-banded cockroach has two pale cross-bands and no fully developed wings yet.[9]
Harmless outdoor species
Some cockroach species live outdoors and may walk or fly inside, but do not establish a lasting infestation indoors.[10]
Found a larger, dark insect? Also compare the oriental cockroach in the identification guide (in Dutch).

Request treatmentWhat do we agree with you in advance?
Identifying the species and hiding places
We investigate sightings around appliances, pipes, gaps and storage areas. Monitoring traps help assess the spread. In apartments, hospitality premises or ships, we agree which adjoining spaces need to be accessible.
Baiting and source measures
Where appropriate, we use professional gel or bait in targeted places, alongside measures to reduce food, moisture and shelter. The species and situation determine the method. Do not spray around the bait yourself: it can interfere with the treatment plan.
Monitoring and follow-up treatment
We assess new catches and sightings. Egg cases and hidden harbourage may make follow-up necessary. You receive a report identifying treated areas, cleaning instructions and agreed checks or repeat visits.
The species, spread, accessible hiding places and planned monitoring determine the proposal. You see which treatment and checks are included. The scope for larger shared premises or multiple units is agreed first.
Our approach
How we control cockroaches
We treat hiding places and check whether activity remains. We discuss the approach, preparation and costs with you beforehand.
- 01
Inspection and species identification
We identify the species and look for hiding places, for example around kitchen appliances, gaps and pipe penetrations. We also investigate the spread within the home.
- 02
Plan and preparation
You know what we will do and what it costs. We explain which areas to clear and the precautions needed for food, children and pets.
- 03
Monitoring and treatment
We treat around hiding places in a targeted way, using authorised gel or bait where appropriate. Monitoring traps help track activity.
- 04
Checks and follow-up
We check catches and new sightings. If activity remains, we investigate the cause and agree further treatment with you.
Eversor works with local pest-control technicians throughout the Netherlands. We discuss your enquiry, the preparation needed and arrangements for checks.
When do we involve the landlord, owners’ association or neighbours?
If there are signs of spread through pipes, shared areas or neighbouring homes, we discuss a coordinated inspection. Activity reported by neighbours is relevant information, but does not prove where your cockroaches came from.[3]
Report recurring activity to your landlord or property manager. Coordinate access, preparation and any treatment.
Treatment
Targeted control and limiting further activity
Treatment depends on the species, the affected areas and how the room is used. Reducing food, moisture and shelter is part of the approach.
Monitoring: locating remaining activity
Insect glue traps help detect insects and track activity by location. We record their positions and compare findings during checks. An empty trap in one place does not prove that the entire home is clear.[5]
Targeted treatment with gel or another suitable method
Gel or bait may be suitable for a confirmed cockroach infestation. Placement around hiding places and routes is important; a random position in the room is not enough.[5]
We only use products authorised in the Netherlands for the relevant application and follow the current conditions of use. These determine placement, food protection and precautions for children and pets.[6]
Where appropriate, we combine this with targeted removal of insects and egg cases or changes to hiding places. We discuss what is worthwhile in your home beforehand.
What can you do right now?
- Keep food sealed and clear crumbs, grease residues and waste.
- Have leaks repaired and keep accessible damp areas dry.
- Reduce loose cardboard and check used appliances, furniture and boxes before moving them.
- Record sightings and take photos before removing signs.
- Coordinate sealing gaps and pipe penetrations with the inspection. Keep ventilation functioning.
Preparation and aftercare
Only clear the agreed cupboards and areas. Do not move suspect items to other rooms without discussing it with us. Tell us which products you have already used and whether children or pets are present.
Leave installed bait and monitoring traps undisturbed. Do not spray another product nearby, and only clean treated areas according to your instructions. Record new sightings for the follow-up check.[5]
Costs
How much does cockroach control cost?
The price depends on the spread, access to hiding places and the treatment and checks needed. You receive clarity about the work and costs beforehand.
We agree which checks are included and when further treatment may be needed. We discuss any additional work and costs with you first.

Case studies and arrangements
Case study: Maasvlakte
A bulk carrier at Maasvlakte reported cockroach activity at 02:00. Our Rotterdam case overview describes this assignment aboard a ship. A ship requires different access and scheduling from a home or commercial kitchen.

Questions
Frequently asked questions about cockroaches
I have seen one cockroach. Is that already an infestation?
Not automatically. One sighting may be an insect brought in with belongings or an outdoor species, but with an indoor species you may not immediately see more insects either. Have the species assessed. If it is an indoor species, or there are repeated sightings, nymphs or egg cases, we also investigate hiding places and possible reproduction indoors.[4]
Do cockroaches mean my home is dirty?
No. They can arrive with goods, luggage or used appliances and spread from another part of a building. A clean home can be affected too. Reducing food residues and moisture does help with control.[7]
Can I control cockroaches myself?
You can record sightings, seal food and reduce moisture and clutter. For a confirmed indoor species or recurring activity, a professional adds species identification, investigation of hiding places and targeted treatment. Only use a product if its Dutch authorisation permits your use, and follow the label.[6]
Will an aerosol spray help?
A single spray does not necessarily reach hidden insects and egg cases. Some sprays can repel insects and interfere with bait. Tell us about products already used and do not combine treatments on your own initiative.[5]
Do I need to leave my home or empty the kitchen?
That depends on the treatment. You receive specific instructions beforehand about access, food, children, pets and any rooms that temporarily cannot be used. Do not empty the entire kitchen on your own initiative.
Is one treatment enough?
That depends on the spread and activity after treatment. During checks, we look for new insects and nymphs. If further treatment is needed, we also investigate hiding places, bait uptake and possible new introductions.
Do you also help with cockroaches in business premises?
Yes. We adapt the approach and reporting to how the premises are used. Please use the business enquiry route.
