A good bee hotel will have tunnels that are approximately 6″ (152 mm) long and have disposable or cleanable components. The latter can be achieved through the use of (1) disposable paper liners, (2) reeds that can be easily split open, then thrown away, or (3) routered wood trays that come apart for cleaning. Avoid bee hotels that use bamboo or have unlined holes drilled in wood (neither can be cleaned) and thus become Mite Hotels. Below are ones that seem OK to me. Note that pine and other cheap wood will warp with humidity and age, so opt for hardwoods when possible.

If you’d like to make your own, Native Bee Hives has an excellent page with details on different ways to construct them. I also recommend reading through Nurturing Nature’s pages and videos.

Here’s my guide to avoiding low-quality bee houses that are for sale at most garden centers. If you’re handy, you can also make your own.
