I'm beginning to worry about my earthworm population. There is an ungodly number of them. Stick a shovel anywhere and four or five immediately flop out onto the surface. I've read here: http://www.firefly.org/how-you-can-help.html
, that earthworms compete for the same food as fireflies and can hurt firefly populations.
Has this been your experience? I added earthworms to my yard a couple years ago, not knowing about their being non-native and invasive in some respects. I am willing to start lowering their numbers in some way, but this will obviously be a challenge. I'm wondering if it's worth it. What other ways can I increase the number of fireflies? I live out in the country with a lake in my backyard and tonight I've seen about two or three. I don't use any chemicals, but my neighbors do. My girlfriend lives in the middle of the city and around her house there are many times more fireflies than there are here. She has no water feature in the yard, a trimmed lawn, and lives next to other trimmed lawns also drenched in chemicals. What am I doing wrong?
I miss the fireflies! It was a cold, wet winter last year so I heard this should mean higher populations... but alas...
Thanks in advance for your help.
