EZ Zap Lantern and Bug Zapper, 2-pk

Are flies attracted to this too? Or just mosquitoes?

There is not much info in this.

I took a chance on these since there aren’t any reviews. I bought for my rooftop deck, where I haven’t had a chance to try them out. However, I saw a mosquito in my bedroom last night, so I put one next to my side of the bed. This morning I woke up to see a dead mosquito inside! So happy.
