Make: A DIY Bug Observation Box from Recycled Supplies

Welcome to BUG SEASON! The flowers are bursting open in the garden and the bugs are BACK in a big way! Just this week I’ve seen my first butterfly, box elder bug, bumblebee…even a mosquito (it IS Minnesota, after all). It’s a great time for little ones to get out and peep around the backyard for signs of bug life, and we have just the recycled tool to help them make the most of it – a fantastic bug observation box they can make, decorate and take right outside for invertebrate investigation!

I went into this project with a few specific requirements in mind. I really wanted this observation box to be totally bug-friendly and ethical – creating a nice habitat for THEM as well as being a tool for US. I knew it needed to have a way for bugs to easily get in, but also get out. We needed a good way to watch them from the outside, and I wanted to make sure the box could easily be filled with supplies from their natural habitat AND emptied out.

With all those things in mind, I designed a bug observation box that has a little “door” for bugs on the side, but also opens all the way across the top for easy access and emptying (yay!). There’s a full side of mesh to provide lots of fresh air to our bug friends, but also a big window on the other side that’s clear (recycled) plastic we can easily see through. And as a final touch, we decorated ours with flowers to help our bug box blend into the natural scenery…I’m hoping bugs are as attracted to beautifully handmade art as I am! 😉

This is a project that will probably require some adult help, and it’s a fun way for the entire family to get in on some bug-themed play and learning. I think our little observation box is best used for insect investigation outside – so spread out a big blanket, grab a magnifying glass and enjoy a sunny afternoon outside with the bugs! As it was built to be more of a bug playground, there are lots of nooks and crannies bugs could crawl through, and you may not want those little critters exploring your house.

If you love the look and idea of this bug box, but think the build might be a little much, keep reading because I’ve linked to some simple variations and ways to incorporate more insect play and learning below! One of the easiest ways to simplify this? Instead of cutting it into an A-Frame, just keep the box as-is, cutting out windows for your mesh and plastic screening!

DIY Bug Observation Box Instructions:

  1. Gather your supplies

    Gather up all the basic materials. To make a bug observation box just like ours, you’ll need a cardboard box, a large plastic berry container, and the mesh from a produce bag. HOWEVER, there are TONS of ways to make a bug box with substituted supplies or even completely different items! You can use our box for inspiration, then work with what you have.


  2. Draw cut lines on each side of your box

    To make a box just like ours, you’ll want the two narrower sides of your box to be triangular, and the wider sides to have holes for windows. I planned out the shapes, then drew cut lines on each side of the box with a permanent marker.
    You don’t have to be exact with this, eyeballing it is fine! I wanted the cardboard sides surrounding our cutout windows to be fairly equal in width, and just used the width of the ruler as a way to measure and create fairly equal spacing.

    Note: Remember to size the window openings to fit your supplies – so make sure the window opening isn’t too big for your berry lid/mesh bag.

  3. Cut apart your box and cut out the viewing windows

    Cut down each side of your box at the four corners, so it’s laying flat, then use a utility knife to cut out the triangle shapes, side door, and window openings.

    Important: When cutting, remember to leave ONE box flap attached on a long side of your box (note the flap on the left-hand side below). We’re going to turn this into the flap that covers the top of our bug box.

  4. Cut out a triangle-shaped cover for the window on the side.

    Once you have your basic bug box pattern cut out, use a scrap of the leftover to make a triangular cover for the side door. Make it roughly half an inch larger than your cutout, and make small holes where the white dots are below that a metal brad can fit through.

  5. Paint the outside

    This is an optional step, and admittedly takes a bit longer, but I just love the way it looks! Use tempera or acrylic paint to paint the outside of your bug box (you don’t need to paint the bottom – just the sides you’ll see). Hit it with a hairdryer to speed up dry time.
    You could make your pattern process more fun than what we did by splattering or sponge-painting with different colors of paint!

  6. Attach the mesh window

    Use a glue gun to attach the mesh from a produce bag to the INSIDE of one of your bug box windows. I recommend an adult helping with this step, as it can be tricky to push the mesh down while avoiding the hot glue. You can use a popsicle stick or similar tool to push the mesh into the hot glue around the edge.

    We also glued a piece of green paper to the floor of our bug box to simulate grass.

  7. Attach the clear recycled plastic window

    Flip your box around to the other side and hot glue the clear plastic berry container cover on.

  8. Glue one long of your box to both ends, and form a flap over the top of your bug box

    We’re going to bend the cardboard over the top of our bug box to create a velcroed flap, so gently bend it over the top and make a nice folded crease in the box.

    Use a hot glue gun to glue the side of your bug box with the flap to the triangular sides of your bug box.

  9. Glue the other side of your bug box and attach velcro strips at top

    Flip your box to the opposite side, and use a glue gun to glue halfway up both sides. We’ll be leaving the rest unglued so that we can easily pull that long open when we want to access the inside.

  10. Decorate and fill with nature finds to start attracting bugs!

    This is an optional step, but you can add some pizazz to your box with decorations! You can use the garden as inspiration to make your own painted flowers as we did, decorate with natural materials, or use any decorative craft supply you’d prefer! Put your name on it, make a “welcome, bugs!” sign or just leave as is.
    Fill your box with a couple of rocks, twigs, or other backyard finds, then set your bug box outside in a shady spot – leaving the side door open for visitors. You’ll be amazed at the number of bugs that will come to investigate!

When dealing with actual LIVE bugs it’s always good to remember that some bugs are okay to touch and others are not, so a good rule of thumb is to stick to observation and keep it outside. As with all animal-watching patience is required – treat the bugs with the same respect you’d treat anything else, and be gentle when moving or turning your bug box to see. When it comes time to bring your box inside (our particular version is NOT waterproof), gently turn your box on its side and empty all the supplies out, making sure all bugs have safely gone back in the grass or gardens with them.

For little bug-lovers who may be interested in keeping a “pet” bug, you can use it as an indoor habitat along with one of our DIY clothespin cicadas, or another crafted bug (keep reading for some more ideas…). This kind of pretend play is a wonderful way to introduce younger kiddos to the idea of pet responsibilities. They can clean out their bug box, freshen the nature supplies, “feed” their homemade bugs with bottlecaps full of cut leaf “food” and water.
