Mosquitoes have been awful here in the Pacific Northwest this summer. We had a larger bug zapper and it just wasn't doing the trick so we decided to add a smaller 1/2 acre insect killer to our property (2.5 acres). This went to work the first night and has not disappointed. Made much better than the older model Stinger brand we have. This takes small attractant packs that fit into the bottom of the unit to help lure insects. The attractant can be pricey, and this works well with or without it. Very happy with this purchase. I ended up ordering another larger zapper by Flowtron as well. I purchased this item at full cost. I rely on product reviews just like others to help make my purchase decisions so I try each product very carefully before reviewing and always do my best to leave honest opinions  and provide as much facts as possible based solely on my experience.
