    Great find.

    Placed a new one on a day we were constantly going in and out of house. 5 flies caught over night. Works best when room is dark and that’s the only light.

    Not very effetive

    I haven't seen many flying creatures attracted to the light. At least not many victims on the sticky paper.

    Stem light trap

    It was a waste of my money, insects (fruit flies) it was as if the insects if they could speak 🗣️ would say “guys I fly and land all around this gadget and it doesn’t attract me at all”. So needless to say it’s been up a whole week and hasn’t sizzle not 1 fruit fly!!!
