It works! Keep in mind that ithis is indiscriminate and will attract most flying insects, including moths,. If you don't want them all dead, don't go with this zapper. We hung this out on a lawn pole&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Achla-Designs-TSW-37-91-Inch-Single-Pole-Heavy-Duty/dp/B004T34BA4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Achla Designs TSW-37 91-Inch Single Pole/Heavy Duty</a>&nbsp;and have it set to come on at 30 mins after sunset using a timer with a photoelectric eye to turn on at dusk&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Woods-59746-Outdoor-24-Hour-Photoelectric-Timer-w-Wireless-Remote-Control-3-Outlet-Black/dp/B00E5VEBK0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Woods 59746 Outdoor 24-Hour Photoelectric Timer w/ Wireless Remote Control & 3-Outlet, Black</a>&nbsp;and I'm very happy with this combination. It doesn't waste the bulb by having it run all day and it is effective in drawing in the critters and zapping them into ash. This zapper appears well built and sturdy enough for prolonged outdoor use. I've only had it outside now for a few months, but it shows no signs of wear or oxidation. Every so often a really big bug will get zapped and the zapping noise will last a while (a minute+) and it's a little worrying, but eventually the zapper finishes it's job. You can see small blue sparks when the bugs die. It works as advertised!
