Compared to photographing them, catching fireflies is about the easiest thing to do. And in the summertime, many people love to run around a field with mason jar in hand, to get closer to these fascinating insects. If you want to catch fireflies, make sure your jar has pierced holes, so the fireflies can breathe, and be sure to release them within a day or two. Click here for more tips on safely catching fireflies.
In the northeastern part of the United States, firefly season is at its peak in the weeks after July 4. But if you’ve noticed fewer tiny twinkling bugs in your backyard this summer, that might be because there’s evidence to show that firefly populations are on the decline. But do not despair. Firefly.org has outlined a few ways that you can help protect fireflies. And the Gardenista editors are republishing some of them here in hopes that our fellow gardeners can help spread the word.

1. Turn off outdoor lights: Fireflies use bioluminescence to communicate and attract mates. There’s evidence that light pollution from humans interferes, making it harder for fireflies to mate and breed.
2. Let logs and natural litter accumulate: Rotting logs and natural litter on the forest floor can provide crucial habitats for firefly larvae.
3. Get a fountain: Most species of fireflies thrive in marshy areas near standing water. If you don’t live by a natural water source, consider adding a small pond or fountain—or even a birdbath—to your garden.

4. Don’t use pesticides and fertilizers: It shouldn’t be surprising that pesticides that get sprayed to eradicate one type of insect can have detrimental effects across species. Although there’s no direct link between fertilizer use and firefly decline, it’s common sense that you will create a richer natural environment if you avoid synthetic fertilizers and chemicals. Better for you, better for the bugs.
6. Plant trees: Trees—especially pines—provide a protective umbrella under which fireflies live and can mate. The needles that fall to the ground underneath pine trees create an additional habitat.
7. Talk to your neighbors: This is probably the best step you can take. Imagine how many more fireflies you’d see if the whole neighborhood just agreed to turn off the lights?
