Hedgehogs need food and the best food for them is bugs. Bugs won’t attract unwanted visitors like rats, cats and foxes but are preferred by hedgehogs.
A well-built hotel can shelter anything from Hedgehogs to toads, solitary bees to bumblebees, and ladybirds to woodlice. You can build your bug hotel at any time of year, but you might have the most natural materials such as straw, dry grass and hollow plant stems in autumn.
Here are a couple of examples of different scales but a few bamboo canes tied together and hung can be a great start too.
