Our WoodStone® range of nest boxes have been designed and developed as part of our professional Vivara Pro range. Every WoodStone® nest box from CJ Wildlife is guaranteed for 10 years. Constructed from a mix of concrete and wood fibres, WoodStone® nest boxes safeguard against attacks from predators including woodpeckers, cats and squirrels. These nests have been developed specifically for House Martins and research has shown that the white coloured back panel helps to attract these agile birds. Fixings are included, making the nests simple to hang under the eaves of your house or outbuildings.
