Digging through the potting shed usually yields two things: brown recluse spiders and junk.
Yesterday, I tripped over a kinked rubber hose and knocked over a cardboard box of burnt-out incandescent bulbs.
Most sensible people throw dead light bulbs in the trash.
But gardeners are stubborn scavengers by nature.
If you spend enough time kneeling in damp compost, you start looking for ways to repurpose everything.
Figuring out how to create DIY light bulb fireflies, ladybugs, and more is actually a decent rainy-day project.
It keeps you out of the mud, and it uses up trash.
The Messy Reality of Garden Art
Let me warn you right now.
Glass breaks easily.
Getting glass splinters mixed with the grit and soil under your fingernails is a miserable experience.
Wear heavy leather gloves when you handle these old bulbs.
I have shattered more than a few while clamping down too hard with pliers.
It makes a terrible popping sound.
Then you spend twenty minutes picking shards out of the woodchips.
Gathering Your Materials
You need dead light bulbs, obviously.
Standard A19 bulbs work best for fireflies and bees.
Those smaller, round globe bulbs make decent ladybugs.
You also need outdoor-grade enamel paint.
Back in 2005, I moved to a harsh, dry climate and stubbornly tried to grow delicate tropicals.
I lost dozens of expensive plants to the blistering wind and relentless UV rays.
That same aggressive sun will strip cheap acrylic craft paint right off a glass bulb in two weeks.
Buy the good exterior paint, or don’t bother.
You will also need copper or aluminum craft wire (16 or 18 gauge), wire cutters, and needle-nose pliers.
Prepping the Glass Canvas
Bulbs from the garage are usually coated in grease and dead fruit flies.
Wash them in warm, soapy water.
Dry them off with an old rag.
Here is a tedious but necessary step.
Take fine-grit sandpaper and lightly scuff the glass.
It sounds awful, like fingernails dragging across a chalkboard.
But scuffing gives the glass “tooth,” allowing the paint to actually stick to the smooth surface.
Crafting the Fireflies
Fireflies need a glowing abdomen.
Paint the bottom third of the bulb bright, neon yellow.
Paint the top two-thirds black or dark brown.
Let it dry.
Waiting for paint to dry is nearly as boring as waiting for tomato seeds to germinate.
Once dry, grab your copper wire.
Wrap the wire tightly around the metal screw base of the bulb.
This forms the anchor point.
Cut two longer pieces of wire and twist them into the shape of wings.
Attach these wire wings to the anchor point on the base.
You can add shorter wire pieces to mimic legs.
Painting Ladybugs and Bees
Ladybugs require less wire and more paint.
Paint the entire bulb red.
Once that dries, paint a black semi-circle near the metal base for the head.
Dip the wooden end of a paintbrush into black paint to stamp dots onto the red back.
I like to place these fake ladybugs near my rose bushes.
It is an ironic joke, considering the fake bugs do absolutely nothing to control the very real aphid infestations I fight every June.
For bees, paint alternating yellow and black stripes.
Attach wire wings to the base, just like you did for the fireflies.
Hanging Art Without Killing Your Plants
Now we reach the actual horticulture part.
How you place these in the garden matters.
In 1998, I rotted out a prized collection of rare Phalaenopsis orchids by overwatering them.
I loved them too much, and I smothered their roots.
Similarly, you can easily kill a young tree by hanging art improperly.
Do not wrap stiff copper wire tightly around a living branch to hang your glass fireflies.
As the branch grows, the wire will bite into the bark.
This girdles the cambium layer, cutting off nutrient flow and killing the branch.
The Royal Horticultural Society warns repeatedly against improper tying and staking for this exact reason.
Instead, use loose loops of soft twine to hang the wire bases.
Alternatively, hang them from dead wood, fences, or metal shepherd’s hooks.
Mounting Bugs on Stakes
Sometimes you want your ladybugs resting down in the foliage.
You can glue the metal base of the bulb to a wooden dowel or an old bamboo plant stake.
Use a heavy-duty, outdoor-rated epoxy.
Hot glue will melt and fail the first time the temperature breaks ninety degrees.
Shove the stakes into the soil among your hostas or ferns.
According to the Missouri Botanical Garden, placing non-reflective garden art low in the foliage won’t disrupt native ground-nesting bees.
Just be careful where you step.
I have accidentally kicked my own garden art while dragging a heavy bag of mulch.
Dealing with the Elements
Accept that these decorations are temporary.
Nature reclaims everything eventually.
The wire will oxidize and turn green.
The paint will eventually chip off after a rough winter.
Sometimes it rains for a week straight and your painted bugs end up looking like peeling, abstract blobs.
That is just how it goes.
Gardening is an exercise in managing decay.
When they look too ragged, toss them out and make new ones.
Why We Bother
Creating these little DIY light bulb fireflies, ladybugs, and more is just a way to kill time on a slow afternoon.
They won’t fix your powdery mildew.
They won’t pull the bindweed out of your vegetable patch.
But when your lower back aches from hours of weeding, it helps to see a flash of yellow glass hovering over a fern.
It adds a tiny spot of color to the chaos.
And honestly, anything that keeps an old light bulb out of the landfill for another year is fine by me.
Now, go wash the dirt off your hands.
The paint adheres much better when you don’t have potting soil stuck to your fingertips.
