Got a housefly problem out of nowhere. Ordered this and another famous brand in hopes of getting rid of them. Useless.. It did not catch even one fly. Ended up buying clear window sticky traps which worked way better.

Unfortunately it caught nothing for us. They just fly around it but never land. We verified we installed it correctly. However, they just seem disinterested.

Beeare these will trap geckos
Never again buying these or using them. A gecko got stuck to it and I spent an hour freeing the poor little buddy with olive oil and waiting for it to be able to unstick. Lots of q tips and oil later, thank god the gecko is okay!!! I guess that’s the point of them for bugs but I couldn’t let the poor gecko suffer. So yeah… never again using.

The bugs were laughing at me
Didn't catch a single gnat. Not even a spec of dust. I'm very happy other people have had luck with this but the gnats in my apartment were not drawn to it in the slightest.
