Our species-appropriate wild bee house with grass paper nesting tubes is stormproof thanks to a practical wall bracket, pre-drilled in 4 places for absolutely stormproof installation! The bee house offers a welcome place for a large number of the 560 native wild bee species to lay their eggs safely and protected. Thanks to the various-sized nesting cavities (5-8 mm diameter), which are 100% splinter-free, our wild bee hotel attracts almost every native wild bee species: 🐝 5-7 mm nesting cavities: Masked bees, mining bees, and scissor bees 🐝 6-8 mm nesting cavities: Leafcutter bees 🐝 7-8 mm nesting cavities: Mason bees The professional, durable nesting tubes are extra strong and water-repellent. They are made from particularly eco-friendly grass paper, which is produced in an energy-saving manner on fast-growing grass. The advantage over bamboo and reeds is that the rolled tubes are completely splinter-free, preventing any wild bees from fatally injuring their wings 🐝💚 Your professional bee hotel is handcrafted to a high standard in close collaboration with workshops for people with disabilities in the Palatinate region of Germany, who are paid a fair wage above the minimum wage. The 2 cm thick local solid wood from sustainable forestry comes from our trusted forester and sawmill. In combination with stainless steel cross screws, it promises a very long lifespan! For the sake of the animals and our environment, we exclusively use natural wood without chemical treatments! The wild bee house is 100% rainproof! We even carefully coated the roof with natural water-repellent linseed oil, so you get a beautiful pet house that can withstand the elements for a long time! Together we are taking action against insect extinction and creating more habitat for wild bees! Insect populations of flying insects have already declined by over 75% within 27 years, due to monocultures, too many pesticides and less and less natural habitat! This particularly affects wild bees, which are essential for the pollination of countless plants. It is high time to stand up for the animals before it is too late!
