Insect Hotel

What is an Insect Hotel?

Insect hotels are winter lodgings for your backyard crawling and flying bugs. Usually made of found or upcycled materials around your yard, these hotels consist of different suites catered to each little bug’s preferred lodging taste. Most hotels are constructed with a strong protective frame of wood boards or pallets and are filled with a variety of bug-friendly materials like straw, cork, sticks, or pinecones.

Why Build an Insect Hotel?

Insect hotels provide safe areas for solitary insects to hibernate over winter. Big lawns and the lack of dead wood in our yards leaves wild bees, spiders, and ladybugs without a place to live. Building accommodations for beneficial insects like ladybugs or flying pollinators can help benefit both your environment and your garden in the spring.

Some creatures like it damp, others—prefer a dry home. Ladybugs hibernate during winter in piles of dry twigs and leaves, which you can provide in your insect hotel. Might be better to think of it as habitat or a condo. What you really want is long-term residents. Photo by Sarah Barker at the Shrewsbury flower show. Flickr

Insect Hotels for Bees

insect habitat
Solitary bees like sun. The ideal location for an insect hotel is in full sun and protected from the weather. This will ensure that the heat required for the brood is present, and wind or rain will not destroy their nest. Provide that, and the flowers, and they will come. www.sav-überlingen.de

solitary bee cells
Solitary bees are different from social bees (such as honey bees) in that every female is fertile and makes individual nest cells for her offspring. Some native bees are ground nesters but more than 30% are wood nesters. The female wood nester will look for pre-existing cavities such as hollow stems or holes in wood that are just the right size to use as a nest.

The female typically creates a series of compartments (cells) and within each cell she will lay an egg on top of its future food source. The female bee will make numerous trips to flowers collecting pollen and nectar that she will pack into each cell. On these trips, the female wild bee pollinates plants and food crops. It can take anywhere from 20 to 30 trips to fill each cell with food.

When she is satisfied with the amount of food, she lays an egg, compartmentalizes the cell, and moves on to creating the next cell. When she feels the chamber is complete, she seals off the end, and moves on to filling a new chamber. The last cells (those closer to the opening) contain eggs that will become males, as males hatch before females.

Although each species is different, mason bee females live for about a month, and can build a cell nest for about two eggs every day. The larva hatches from the egg after a week or more and begins to eat the provided pollen and nectar. After the food has been eaten, the larva spins a cocoon and pupates within the cell.

By the end of summer or early fall, the bee transforms but remains in the cocoon as an adult throughout the winter. In spring, the males begin to emerge by chewing their way out. The females, which are almost always in the deeper cells of the tunnel, emerge a week or two later.

While solitary females each make individual nests, some species prefer to make nests near others of the same species, giving the appearance to the casual observer that they are social. Nest photo by Mike N. of Vancouver, BC.

Many solitary bees are very small and you may not have realised they are bees. More species of bees live alone, than in hives. Wild bees are considered to be as important to the food chain as bumblebees and honeybees. Honey bees are not native to the Americas (see below). Photo by Bob Daamen, Flickr

Who Lives in an Insect Hotel?

Wasps: cuckoo wasps, parasitic wasps and many more species…

Dragonflies, beetles, lacewings, ladybirds. moths, spiders, frogs, newts, hedgehogs, et al… www.wildbienenstand-neuhof.de

Bees: leafcutter bees, masked bees, mason bees, digger bees and hundreds more…
Bumblebees nest in hollow trees and in rodent burrows. They are among the first bees to emerge in the spring and the last to disappear in fall. They are superb pollinators of tomatoes, blueberries, cranberries, clover, and more. Bumblebees can “buzz pollinate” by hanging on a flower and vibrating with their flight muscles to release pollen.

Mason and Leafcutter Bees select existing hollow stems and bored holes in which to build their multiple nest chambers. They carry pollen underneath their bodies rather than on their legs like most bees, and the pollen falls off rather easily. Mason bees are first-class pollinators of many fruit crops, toiling long hours and in inclement weather. Squash and Gourd Bees help pollinate up to eighty percent of squash, pumpkins, and melons. They are ground nesters, so it is important to leave some open dirt for the these very important bees as well.

How to Build an Insect Hotel

    • For a simple hotel, drill holes 1/4″ to 3/8″ in the ends of logs, or cut some bamboo sticks of equal length, and stuff in a wooden box.
    • Layer old pallets.
    • Logs, drift wood, cut bamboo, straw, dry reeds, roofing tiles, cob.

Do not use softwood for bees, as the drilled holes might fill with resin and suffocate the bees! Make sure all wood is free of chemical preservatives.

The folks at Crown Bees say that drilled holes and bamboo are not the best for mason bees, since parasites or disease might also invade these homes. They say that mason bees prefer reeds or paper straws, which also allow you to observe the mason bee’s nest. Yet they say even the reeds might attract pests after three years. Crown Bees suggests that trays which are like a block of drilled wood that comes apart for cleaning are best.

Watch the tray video here:

Some suggest spraying your existing drill holes every couple of years with a 5-10% bleach solution to keep them free of disease. You might also wish to redrill the holes in case anything is stuck in there (after the bees are gone). Actually it would probably be best to have two sets of nesting blocks, after each washout, drill and store inside, and put out the alternating block.

  1. We photographed a nice bee hotel in the Paris Botanic Garden last year.

    Would this web site like a copy of the photo? If so, please email me giving suggested size in kb of JPEG file.

  2. Recent research published in Canada suggests that unmanaged insect hotels like these can become population sinks for solitary bees.

    Search for ‘‘Bee Hotels’ as Tools for Native Pollinator Conservation’ on Plos One.

    Attractive as they are they, they can encourage bee parasite populations to grow stronger than in a natural environment and overwhelm the emerging generations of cavity-nesting bees.

  3. Thank you for gathering all these wonderful images and for the helpful links. Not just inspiring, in fact, but practically helpful too 🙂

    I wonder if an answer to Paul Bee’s point would be to have lots of smaller habitats rather than big ‘insect hotels’? This might mimic natural habitats better – and also spread the population out, making depletion less likely… Just a thought, as my enthusiasm was punctured somewhat by reading that.

  4. i really think this kind of pic is really helping kids to understand what kind of homes that people do for bees and what bees do for them self

  5. Will Mason bee homes be too hot if I use tall 24-25 ounce beverage cans to stuff Knotweed stems into, to secure them in bundles, in a larger ‘house’?

  6. I like the pictures of the insect hotels. I would like to have faith that only ‘nice’ insects would move in. Ladybugs, bees, and moths would be cool. But I live in the high desert and have black widow spiders living on my property. The insect hotel would make a great home for these dangerous arachnids. Scary…

    I killed 5 black widows last year, one in the house by my small dog.

  7. What a great article. I’ve just bought a small insect house but am now inspired to also create a larger recycled version in my garden

  8. Hi I live in a high bear population area. I would love to help the bees by providing bee hotels for them but I have a big concern about the Bears. They come around enough and I do not want to attract them. Would this be a concern that the hotel would attract the Bears?
