"Moth trap!"
Bought this a while ago for pantry moths in my kitchen - but turns out they're not attracted to light, so packed the light away. Move forward to the point where my newish conservatory has an infestation of moths and their leaf-rolling caterpillars, decimating all my plants. Evenings spent wielding fly swats and inspecting and squishing all leaves had little effect - then I remembered this light. Well, 1st night and paper's covered in moths, with more lined up on the white wall for convenient swatting. Finally have confidence might actually win. Thank goodness you still have the refills!
