Not all bugs and insects like to not be in the shade everyday: solitary bees like a warm sunny spot, so put tubes for bees on the sunniest side of the habitat, or put them elsewhere in the garden.
Choose a level, even surface: the hotel may end up fairly heavy, so will need a firm base.
We chose the far side of the football pitch as the site for our bug hotel. The site is surrounded by an overgrown hedge and a number of types of trees, some that are fruit bearing.
We believe that we have chosen the best possible location for attracting a wide variety of bugs and insects. Time will tell!!
