By providing a safe haven for species of solitary Hymenopterans, such as wild bees, sand wasps and common wasps, you can promote these species in your garden. These species fulfil essential ecological roles including pollination and pest control.
Ideally place the nesting aid in a sunny site that is protected from wind and rain. Examples of good sites include allotment sheds, pergolas, walls, gardens and even balconies up to the third or fourth floor. Remember to leave the aid outside during the winter otherwise the insects will emerge from their winter hiding places too early and die. The house is made from wood-concrete; an exceedingly durable, rot-proof and breathable natural material designed to mimic the properties of natural nest sites and last 20 - 25 years.
