Martens Control Netherlands: Animal-friendly Dispelling and Permanent Repelling
Are you suffering from stone martens and looking for professional stone martens control netherlands? Then you have come to the right place at Janssen Pest Control. Indeed, stone martens are protected species that can cause major damage to insulation, electrical wiring and cars, but should not be killed. That is why Janssen Pest Control offers effective stone martens control netherlands with animal-friendly repellent methods and permanent exclusion to prevent recurrence.
Why stone martens are so hard to chase off
Stone martens are territorial and always return to their familiar habitat, even after being chased away. This is because they mark their territory with scent and faeces, which attracts new martens. Moreover, they are intelligent and learn quickly to bypass repellents. In addition, they are nocturnal and highly mobile, which makes detection and repelling difficult. These characteristics make professional stone martens control netherlands with expertise in animal behaviour and warding absolutely necessary.
Our integrated approach: chase + repel
We use a two-step plan: first, we chase away the marten(s) with sound, light and smell. Then, we seal off all access points to make return impossible. This integrated approach is the only way to achieve lasting results. Moreover, we work in a completely animal-friendly manner in accordance with the Nature Conservation Act - stone martens are not killed, but only chased away and kept out.

Why Choose Our Stone Martens Control?
At stone martens control netherlands knowledge of animal behaviour and engineering is crucial. This is why Ongediertebestrijding Janssen stands out as an stone marten specialist:
Expertise in Capricorn Behaviour
Our exterminators are trained in marten behaviour and know exactly how stone martens live, move and mark their territory. This is because we recognise their tracks (faeces, scent deposits, running tracks), identify nesting and dwelling sites and determine access routes. This knowledge is essential because without understanding the behaviour, repelling always fails.
Animal-friendly repellent methods
Stone martens are protected under the Nature Protection Act. We therefore use only legally permitted, animal-friendly methods:
- Sound: Ultrasonic devices and radios (stone martens avoid continuous sound).
- Light: Bright LED lights and motion sensors (martens are nocturnal animals that avoid light).
- Fragrance: Commercial repellents and natural fragrances (toilet cubes, vinegar, tiger poo extract).
- Timing: Repulsion at appropriate time (not during reproduction time when young are present).
These methods send the marten away without harm, which is ethically and legally correct.
Permanent Exclusion: The Crucial Step
Repulsion without fencing is temporary - martens always return. We therefore seal all access points:
- Holes and gaps: All openings larger than 5 cm are closed with sturdy mesh, sheets or foam.
- Roof tiles: Loose roof tiles are secured or fitted with special marten grates.
- Vents: Equipped with fine-mesh sturdy mesh (stone martens cannot pass through).
- Trees and shrubs: Branches growing against the roof are pruned (martens climb along this).
This physical barrier prevents permanent return.
Damage Inspection and Consulting
Stone martens often cause significant damage before owners notice the problem. We therefore inspect:
- Insulation (torn up for nesting material)
- Electrical wiring (bites through cables - fire hazard!)
- Water pipes (bite marks)
- Storage (damaged stuff in the attic)
You will receive detailed advice on any repairs and contact with your insurance if necessary.

Our Approach: Step-by-step stone martens control
We use a proven method at stone martens control netherlands which guarantees permanent results:
Step 1: Thorough inspection and damage inventory
Our specialist performs a complete inspection of your attic, crawl space and exterior of the property. We look for:
- Traces of presence: Faeces (8-10 cm long, twisted, strong-smelling), urine stains, running tracks in dust, hair.
- Nesting sites: Collected insulation material, stored boxes as shelter.
- Access points: Holes in roof, loose tiles, gaps in facade, vents without mesh.
- Damage: Damaged insulation, cables bitten through, bite marks on pipes.
- Activity pattern: Recent versus old tracks to determine if marten is active.
This inspection takes 1-2 hours and is crucial for an effective approach.
Step 2: Timing Check - Reproduction period
Stone martens reproduce in March-April and young are born in April-May. If young are present (we hear scratching sounds), we wait to chase them until they are independent (late June). Indeed, chasing with young is not only prohibited by law but also ineffective - the mother stays with her young. This timing check avoids legal and ethical problems.
Step 3: Dispersal with Multi-Sensory Approach
We combine multiple repellent methods for maximum effect:
Sound: We place ultrasonic devices (varying frequencies that irritate stone martens) and/or a radio on talk station (martens avoid human voices). These devices work 24/7.
Light: Bright LED lights with motion sensors or continuously on (martens are nocturnal animals that avoid light). Flashing LEDs are extra effective.
Fragrance: We apply repellents to walkways and resting places: commercial marten sprays, toilet cubes (scent of human urine), vinegar-soaked cloths, tiger poo extract (natural enemy scent).
Disturbance nest: We remove collected nesting material so that the marten perceives its habitat as unsafe.
This combination makes the attic unlivable for the marten within 3-7 days.
Step 4: Verification of Departure
After 5-7 days, we check if the marten has left by:
- Placement of meal tracks at tired entrances (paw prints visible if marten returns)
- Checking for new droppings
- Inspection with wildlife camera (optional if in doubt)
Only when we are sure the marten is gone do we start repellent work.
Step 5: Permanent Barrier - Sealing off entrances
This is the most important step. We seal ALL access points:
- Holes in roof/gable: Seal with galvanised metal mesh (minimum 1 cm mesh size), wooden boards or PUR foam reinforced with mesh.
- Loose roof tiles: Fix or replace. Optional: install marten grates.
- Vents: Equipped with sturdy, fine-mesh stainless steel mesh that martens cannot bite through.
- Chimney: Hood with mesh if needed.
- Climbing routes: Advice on pruning trees/shrubs against facade.
We use only durable materials that martens cannot bite through or tear apart.
Step 6: Final inspection and warranty
After 2-4 weeks, we perform a final check. We check whether:
- All yards intact
- No new traces of marten activity
- No new access points created
You will receive a guarantee on our repellent: if the marten returns due to our repellents, we will repair it free of charge.
