Using this insect hotel is easy. Find a tree or a post away from the prevailing winds in your garden or on your balcony and install the hotel there. That's where solitary bees and ladybugs will find it. As for the age recommendation, it's great for kids 7 and up to observe and learn about nature. When it comes to maintenance, check it once in a while to make sure it's in good shape. If there's any debris, gently clean it out. Don't use any chemicals near it, as that can harm the insects. Enjoy watching your garden come alive with these helpful little guests!
