That overripe banana in your fruit bowl could bring more butterflies to your yard

There's a simple way to turn an overripe piece of fruit into a backyard boost: Use that forgotten banana as a snack for butterflies.

For gardeners hoping to attract more pollinators without spending money on special tools or products, this trick is about as low-effort as it gets.

Here's what to know

Rather than tossing a banana once it turns mushy and overripe, a gardener can put it outside as butterfly food. According to House Digest, butterflies are drawn to bananas because the fruit is packed with the sugars they use for energy.

An overripe banana has about 13 grams of glucose and fructose in each 100-gram serving. That's around 10 grams more than what's in an unripe banana, which explains why butterflies may be more interested in one while moving through a garden or yard.

Location affects when this works best. Butterfly season varies by region but often falls in late spring, summer, and autumn, so the fruit should go out then, when butterflies are already active and feeding.

House Digest recommended two options: placing the banana in a small wire holder and hanging it from a tree, branch, or pole, or mashing it onto a plate in a sunny area if there's nowhere to hang it. In either case, it should be easy for butterflies to spot and reach, with water nearby.

More background

Butterflies do more than make a space feel lively. They also pollinate plants, which supports flowers, herbs, fruits, and vegetables.

Gardening can help people save money on produce, enjoy fresher and better-tasting food than store-bought options, and spend time moving outdoors. It can also support mental health by creating a calming routine and physical health through digging, planting, watering, and regular yard care.

For people using their yards to grow their own food, attracting pollinators can be especially helpful. A more welcoming garden ecosystem can help plants thrive without store-bought interventions.

Instead of throwing away fruit that's too soft to eat, gardeners can repurpose it in a way that supports beneficial insects while giving kitchen scraps a second life.

What can be done?

Set one overripe banana outside in a sunny spot where butterflies can easily find it.

The hack may take some time to work, so a quiet start doesn't necessarily mean it failed. Butterfly activity depends on the season, the weather, and the location.

House Digest warned that sugary fruit can also bring in wasps and other insects in addition to butterflies. If that happens, move the feeder to another part of the yard to try to limit those unwanted visitors.

Replace the banana once it dries out, gets eaten away, or grows mold.
