Bee Insect Hotel Structure

Good materials to construct insect hotels with can include using dry stone walls or old tiles. Drilled holes in the hotel materials also encourage insects to leave larvae to gestate. Therefore different materials, such as stones and woods are recommended for a wide range and diversity of insect life. Logs and bark, and bound reeds and bamboo are also often used. The various components or sizes of holes to use as entry of an insect hotel attract different species.
• Solitary bees and wasps
Solitary bees, some wasps and bumblebees do not live within a hive with a queen. There are males and females. A fertilized female makes a nest in wood or stone and borred into the wood in order to construct a nursery.
The most common bee hotel is created from a sawn wooden log or portion of a cut tree trunk in which holes are drilled of different sizes (eg 2, 4, 6 and 8 mm), about a few centimeters apart. They attract many bees. The holes have to be tilted slightly so that no rainwater can get in. Stone blocks are also used for this purpose. The holes are drilled quite lengthily into the material but not so far as to create a tunnel to the other side of the wood. Furthermore, the entrances to these access burrows must be smooth enough so that the delicate bodies of the insects are not damaged. Often, with wooden hotels, the exterior is sanded. The best location for a hotel is a warm and sheltered place, such as a southern-facing wall or hedge. The first insects are already active towards the end of winter and would be actively seeking for such a place to settle. Other species like to furnish their nests with clay, stone and sand, or in between bricks.
