Build a Wild Bee House - it's so easy to breed wild bees yourself

The Content Of The Article:


The entrance area in the wild bee house is protected, which avoids birds and allows the winged master builders to pass easily. Therefore please equip the finished nesting aid at a distance of 20 cm with a wire mesh or a blue plastic net. Ideal is a mesh size of 3 x 3 cm. Narrow mesh may not be the net, otherwise it will become a death trap for birds and other small animals. In practice, it has been found that birds already perceive and avoid the color blue from afar.
Tip: The ideal location for a wild bee house is sunny, warm and sheltered. Shady locations remain as empty as nesting aids dangling in treetops.

Roof tiles transform into a wild bee hotel - this is how it works

Strandfalzziegel consist of fired clay and have parallel hollow chambers with a diameter of 6 to 8 mm. Thus, the classic roof tiles are perfectly suited to construct a wild bee house. Above all, cavity-inhabiting wild bee species, such as the well-known mason bees, can easily breed in their own garden with the help of these nesting aids. How to do it right:
  • Stack stranded tiles on firm ground
  • Alternatively, include in the construction of a drywall
  • On one side close the openings with plaster, loam or padding wool
  • Place protective net or wire mesh 20 cm from the opposite side
The bricks can be purchased from roofing companies or directly from the roof tile factory. If heritage-protected roofs newly covered or demolished old barns, Strandfalzziegel abound as waste, which you can get hold inexpensively or for free. The voids in roof tiles from these sources are often contaminated and undergo thorough cleaning prior to use as a wild bee nesting aid.
As a rule, these bricks are 40 cm too long for an Niströhre. Therefore, use an angle grinder to cut up too long strand-cut tiles in half. The rear end is also closed in this case, because flooded with light may not be a Niströhre.

Use marjoram or hollow stems as a nesting aid - Tips & Tricks

Some species of wild bees leave nesting aids made of wood or clay on the left because they favor marrow-like stalks for the breeding of their brood. So that these species do not go out empty, prudent home gardeners construct a wild bee house from adequate plants of your garden. The best options for construction are presented in the following overview:
Mullein (Verbascum)


A prime example from the plant kingdom for a wild bee nesting aid are the strong, marrow-bearing stems of a mullein. When the flower has flowered, cut off the withered flowers. Knock a stick into the ground next to the stalk and attach the stalk to it with binding wire. Decisive for the function as nesting aid is the vertical orientation. The Mark remove the wild bees themselves, by gnawing it out unceremoniously.
After the harvest, brambles are not disposed of but used to build a nesting aid. Place the tendrils with the interface upright along the garden fence and tie them tight. Alternatively, stretch two strings between two posts to vertically align the bramble branches. With raspberry rods, you can do similar things to offer wild bees as a breeding ground.
Tip: Most cavity-inhabiting wild bee species produce only one generation per year. It can last up to 12 months before the finished wild bee hatches from a closed nostril. The finished wild bee house including the nesting aids from plant stalks on this period should not be disturbed if the breeding is to succeed.
Bamboo and reed
Hollow stems are popular with wild bees to lay their eggs in. Bamboo tubes from the garden center or the clippings from reed have proven themselves well for this purpose. How to build a wild bee house:
  • Cut the hollow stems to a length of 10 to 20 cm
  • Individually or bundled and put upright in a container under a rain cover
  • Equip with a bird protection
The horizontal alignment of hollow and stalks as a nesting aid for wild bees has not been successful. It is also disadvantageous to plant stalks on the ground. The high soil moisture is associated with fungal danger, so wild bees females reject this offer a nesting aid wisely.
