This is a full-fledged electric insect killer that uses two 10W insect-catching fluorescent lamps. The fluorescent lamps are automatically turned on and off by a light sensor. I've only used it 2-3 times on the wooden deck of my villa when eating, and I haven't set it up permanently, so there are no noticeable scratches or stains. Please check the photos. It has been tested and is in working order, and all accessories are included. How about using it to keep insects away while camping?
