Inspection before exclusion: advice for properties in Stolberg.

In Stolberg, building protection depends on assessing how accessible a property’s roof spaces, junctions and concealed voids may be. We serve the city as part of the Aachen city region from our base in Linnich. Sealing an opening is appropriate only after confirming that no marten or dependent young could be trapped inside.

How we can help

How we address stone marten activity in Stolberg.

Whether the problem is in an attic, garage, outbuilding or another void, we look at the evidence and the property itself – not just the animal.

Assess signs of activity

Nighttime noises, droppings, urine marks, odor, tracks and damaged insulation may point to stone marten activity. We help determine which signs are relevant.

Plan suitable deterrence

Where appropriate, we recommend lawful non-lethal measures intended to make the affected area less attractive to martens.

Identify entry and exit points

A targeted inspection can reveal how the animal enters and leaves the building, and which gaps or structural details are being used.

Safely exclude martens

Once the animals have left and it is confirmed that no animals, including dependent young, will be trapped inside, suitable entry points can be secured.

North Rhine-Westphalia: legal context

Stone martens are subject to hunting law.

Stone martens are covered by hunting law in North Rhine-Westphalia. Trapping or killing them is not part of our services. We focus on property inspection, suitable deterrence and preventive building protection, always taking applicable rules and animal welfare into account.

Hunting season in NRW: October 16 to February 28
Closed season in NRW: March 1 to October 15
What we offer: inspection, non-lethal deterrence and safe building exclusion – no trapping or killing

Why inspection matters

Find the access route before deciding on a solution.

Many do-it-yourself attempts fail because the actual entry or exit remains undiscovered. Once access points, travel routes and occupied areas are clear, a realistic plan can be developed to discourage repeat visits.

Cleanup & hygienic aftercare

We can also take care of the cleanup after marten activity.

A stone marten can leave droppings, urine residue, odors and soiled materials behind. If you wish, we can also provide professional cleanup and hygienic aftercare for affected areas.

Remove droppings & contamination

We can professionally remove accessible droppings, urine residue and other contamination left by the animal. Depending on the findings, affected areas are cleaned and contaminated materials may require separate treatment or removal.

Enzymatic cleaning, decontamination & disinfection

We select methods appropriate to the contamination, surface and hygiene requirements. Where suitable, these may include enzymatic treatment to reduce odors, targeted decontamination and disinfection when needed.

Helping restore affected areas to usable condition.

Our goal is to remove contamination and restore affected areas to hygienically usable condition where technically and structurally feasible. Repairs or replacement of damaged insulation may need to be addressed separately.

Our process

How we typically proceed.

Each step is adapted to the building, the signs of activity and the legal and animal-welfare requirements.

2. Property inspection

We investigate where activity is occurring and identify likely entry and exit points.

3. Select appropriate measures

4. Exclusion and prevention

Once the animals have left and no young will be trapped, suitable access points can be secured to help prevent re-entry.

Common questions

Questions about marten deterrence in Stolberg.

Can you kill or trap a stone marten?

No. We do not provide trapping or killing services. We specialize in inspection, suitable non-lethal deterrence, entry-point identification and building exclusion.

When is the closed season in North Rhine-Westphalia?

The NRW hunting season for stone martens runs from October 16 through February 28. The regular closed season therefore runs from March 1 through October 15. Hunting rights and animal-welfare requirements must still be respected outside the closed season.

Can a stone marten be kept out permanently?

Often, physical exclusion can provide lasting protection if every relevant access point is identified and secured correctly. All animals must be safely outside before sealing openings.

Do you also provide cleanup and disinfection after marten activity?

Yes. On request, we can remove accessible droppings, urine residue and other contamination. Depending on the findings, we can also offer enzymatic cleaning, targeted decontamination and disinfection where appropriate. We would be happy to prepare a tailored quote.

Which properties can you help with?

Private homes, apartment buildings, attics, garages, outbuildings and commercial premises with accessible roof spaces, voids or other potential entry points.
