Hummelburg - home of the bumblebees

The Content Of The Article:

Have you ever wondered where the bumblebee lives? Who provides the bumblebees with a so-called Hummelburg, knows it in the future exactly. With a bumblebee castle you not only provide a busy home for the industrious lobsters, but also do something for your own garden.
The most important thing:

  • Set up: in the spring to March, just above the ground, the opening should point to the east
  • Nesting material: nesting wool, sheep's wool, dry moss
  • Cleaning: in autumn with water, remove nesting material
  • Special feature: Bumblebees like the color blue, the nest temperature is 30 to 33° C,
  • Mites provide hygiene in the bumblebee nest
So have the own flowers in the spring as the first the fertilization helpers on standby. Already with the warming rays of the sun in March, the sleepy bumblebees crawl out of their castle and make the first buzzing and rumbing attempts. Usually it is sufficient to set up the nesting aid with the opening to the east in the garden, then the bumblebees find themselves alone.
If the entrance to the Hummelburg is colored blue, you will find it quickly. Important for the location is that it may be illuminated only by the morning sun, so that the bumblebees come into the day well, but do not overheat at noon. If bumblebees have moved in, the location of the Hummelburg must not be changed.
The bumblebee castle should be sufficiently isolated and resistant to moisture, be winterized and provide clean nesting wool, so that the young queens survive the winter well.
Unlike bees, the furry brummers fly on cooler days, in the rain or even when snowflakes show up in the sky. In addition, they make the proverbial industrious bee big competition. They fly earlier in the day and swarm in the early evening twilight. The bumblebee also pollinates more flowers than a bee does at the same time. In about ten hours the bumblebee visits up to 1000 flowers.
Hummel Castle
Bumblebees wake up in the spring from their hibernation. This is the time when her queen is looking for a suitable nesting opportunity. She is looking for a suitable place for her nest. The queen needs a small room that she can keep warm. He should not be too big. She searches closely above the ground and flies around every interesting gap and opening that looks like a mouse hole and crawls into it.
In the autumn the people of the bumble-bee queen dies and the new, young queen is looking for a winter quarters.
With a bumblebee castle, humans can offer the useful animals a near-natural nesting opportunity and locate them in the garden. Bumblebees are attracted to the color blue. Therefore, the entry hole should be outlined in blue.
Upside down and buried flower heads should not be used as Hummelburg, as they will run full in the rain and the beneficials would drown. Also from underground boxes is not recommended.
The entrance opening of the Hummelburg should always point to the east and is placed directly on the floor of the garden. The closer the Einflugloch is on the ground, the easier the Hummelburg populated. Would be beneficial to a small but heavy base plate to protect against soil moisture.
The castle should never be placed where the midday sun can shine directly on it. It must not be overheated. Ideal would be a place with morning sun and under trees and shrubs that provide shade. Nesting wool, sheep's wool, dry moss or the like has proven to be a filler. Absolutely unsuitable are viscose or cotton wool, glass wool or filter wadding (Aquaristikbedarf). The animals can gobble up in it and when moist, these materials lump together. In March, the search for the first queens can be expected. Until then, the Hummelburg should be absolutely established. After the entry of the bumblebees the location may not be changed, because after the first approach they memorize this and only return there. They would not find another location.
Cleaning and control
In autumn, the abandoned Hummelburg should be emptied of nesting material and roughly cleaned with water.
Bumblebees are among the most important insects. They are less sensitive to temperature than our bees and are looking for food longer like this. They fly daily, even in bad weather, in almost 18 hours over 1000 flowers. This means that in rainy summers, in addition to bees, they are important helpers for the pollination of fruit and vegetables.
There are 36 species of bumblebee in the German-speaking world that are under strict environmental protection. Their nests may only be removed in absolute exceptional cases.
With nectar-rich flowers that bloom from late summer to fall, every gardener can make his active contribution to bumblebee protection.
