Welcome to brain Stuff, a production of iHeart Radio, Hey brain Stuff Lauren Vogelbaum. Here, bugs need places to hang out, just like everybody else. If you're a garden or yard has a little bit of fallow ground, you could give some insects a place to lay down their weary head and thorax and everything else. Populations of terrestrial insects all over the world are declining at a rate that has
alarmed scientists. In a German study found that the overall biomass of flying insects has declined by up to seventy worldwide in the past thirty years, for reasons that aren't yet completely understood. A study published in January one in the journal Proceedings of the National Academy of Sciences confirmed the same conclusion. Bugs are in trouble, which doesn't bode well for the rest of us. However, assigned is studying the decline recommend protecting wild habitats and spaces friendly to
insects while they figure it out. Enter insect hotels. These are structures that give bugs protection from predators as well as a place to overwinter, nest, lay eggs, and care for their young. Although it's helpful to know exactly what sorts of insects you want to lower to your yard or garden before creating your insect hotel. There are a
few types to consider as you're designing structure. One of the groups of insects hit hardest in the past few decades is solitary bees, which are important pollinators and most often stingless. We tend to think of bees as social and moderately threatening, but most be species nest alone in holes in the ground of The diameter of the preferred
hole varies between species. Meanwhile, centipedes, which eat garden slugs, garden spiders which control other pests would lie and beetles love rotting logs, pollinating hoverflies and avid eating ladybugs prefer bundles of twigs and sticks, while lacewings, which eat many different garden pests from scale insects to mites, like to nest and straw dried grass or rolled up cardboard. Insect hotels are a favor to our many legged friends, but
are definitely an art project as well. The Guinness World Record for the biggest bug hotel, awarded in March of two in the Scottish Highlands, is one ninety nine point nine cubic meters in volume that's seven thousand and fifty
nine cubic feet. It's fashioned from a fallen spruce, bricks, bamboo canes, wood chips, bark, wildflower seeds, clay pipes, and strawberry netting, but any collection of rotting logs, lichens, cinder blocks, wood palettes, and wooden blocks will make many different species happy. The trick is to drill or construct your setup with various sized holes of different depths between about a quarter two half an inch in diameter that's about half to
one centimeter, plus some hollow twigs and stems. It's important to not use plastic sheeting in your insect hotel because moisture can lead to mold that can harm insects. As insects often like sheltered areas, where you locate your insect hotel is an important consideration. Many insects like relatively damn conditions, but solitary bees prefer direct sun and low humidity. It's also important to clean out and restock and refurbish your insect hotel from time to time, using great care not
to disturb any eggs or remaining residents. This will keep your little buddies healthy and coming back to stay. There are lots of guides online to help you build something appropriate for your local critters.
