Simple bee hotels to attract/improve wild pollinators

The idea of bee hotels has been used by many gardeners and farmers to attract wild bees and improve their nesting success during the season. It is also a wonderful tool for education, especially for kids. There are commercial bee hotels that you can purchase (you can google it and many will show up), or you can simply build yours using bamboo or reed stems and scrap wood pieces you find at hardware stores (like the one in this picture!)
