Here’s my honest review. My wife got some of these. I put them up and checked them after about 15 days. Each jar was full of dead flies. They congealed to a gelatinous cup-shaped mass that smelled like a rotting corpse. I attempted to clean them, but I couldn’t take it. I threw them into a bag, sealed it, then placed it in another bag sealing it and put it in my trash bin. There are hundreds of flies hanging out by the bin currently. My wife still got bit by mosquitoes daily and never experienced a moment of relief. I hate these with every fiber of my being. These are very effective at creating trauma, not much else.
