Weasel Stays

Vivara Pro’s weasel stays provide practical, easy to use, and durable shelter solutions designed to support weasels (Mustela nivalis) and other small mustelids in both rural and semi-urban environments. As natural refuges such as hollow logs and stone walls become scarcer due to habitat fragmentation and land management changes, these purpose-built shelters offer safe, long-term alternatives that promote breeding, foraging, and overwintering. Designed and produced in-house, and made in Europe, Vivara Pro’s weasel stays combine ecological expertise, sustainable materials, and professional craftsmanship to deliver reliable, field-tested results for biodiversity enhancement projects across the UK.

Practical, durable shelters for weasels

Developed in collaboration with ecologists and conservation specialists, Vivara Pro’s weasel stays are designed to replicate the secure conditions of natural dens while ensuring easy installation and long-term durability. Each unit provides insulation, safety, and stability — essential for small carnivores that play a key role in controlling rodent populations and maintaining ecological balance.

• Practical design suitable for agricultural land, woodland edges, and urban green spaces.
• Easy to use and install — can be placed on the ground or partially buried for optimal cover.
• Constructed from sustainable, weather-resistant materials for long-term outdoor performance.
• Provides a safe, insulated refuge that protects from predators and temperature extremes.

Each stay is field-tested to ensure ecological functionality, providing reliable habitat support for weasels and contributing to broader small mammal conservation goals.

Why install weasel stays?

Weasels are valuable components of healthy ecosystems, acting as natural pest controllers and indicators of habitat quality. However, agricultural intensification and habitat loss have reduced suitable shelter sites across much of the UK. Installing Vivara Pro’s weasel stays helps to:

• Provide safe and permanent refuges in both natural and managed environments.
• Support biodiversity net gain (BNG) and local nature recovery objectives.
• Enhance ecological resilience by encouraging stable populations of small carnivores.

For urban planners, ecologists, and local authorities, these shelters offer a practical, low-maintenance solution for integrating mammal conservation into land management, restoration, and development projects.

In-house design – made in Europe for quality and sustainability

All Vivara Pro weasel stays are designed and produced in-house and made in Europe, ensuring precision, sustainability, and consistent quality. Each unit is built from environmentally responsible, durable materials that withstand the UK’s varied weather conditions. Local European production reduces transport emissions and ensures dependable supply and product consistency for professional biodiversity projects.
