Bumble bees are among the most important pollinators in nature, and now you can improve the conditions for these useful animals with a bumble bee house - or castle as the manufacturer rightly calls it.

The Bumblebee house is handmade in Germany and made of a special, patented ceramic. The ceramic is very durable and frost-proof - and it has unique temperature properties that absorb heat during the day and release it at night.

In the spring, the bumble bee queen uses the house as a nest, in the fall as a den for the winter.

The housing consists of a top and a bottom plate and can thus be easily opened for cleaning. But the lid is heavy at the same time, so it doesn't just fall off. Wool is included as a good start for nest building.

The opening is painted blue, as bumblebees are attracted to this color.
