Man built this trap in his backyard, and it's disgusting how well it works. The summer months are all about spending time in the sun and warm weather, but one of the biggest drawbacks of the season is the bug life. As soon as the temperature starts to rise, flies, mosquitoes, and other pests seem to come out in droves. Handling these insects can be a challenge if you're not prepared. Luckily, there are a number of simple and effective DIY projects that can help out with pest control in a big way. Take this device. Curdacy of Salem, Indiana, man, Dan Ausley. After years of dealing with horse flies each summer, he devised a simple contraption that takes the pesky bugs out of the picture permanently. Salem, Indiana resident Dan Ausley recently shared a horse fly trap he built in his backyard that works like a charm and has inspired others to build similar ones. His design is fairly simple. The lags hold up a basin that he lines with a back trash bag and fills with soapy water. Suspended over the basin are two sheets of plexiglass suspended at 45° angles. The device actually works because horse flies are visual hunters. They'll spot the black garbage bag, think that it's something they'd like to bite and fly over. They inevitably hit the plexiglass pains and then fall into the soapy water where they drown. For the trap to work, the water has to be replaced every day. Otherwise the flies will smell their deceased brethren. The plexiglass also needs to be kept clean or else they'll spot it. With those simple steps though, horse flies don't stand a chance. Seeing that many dead horse flies is pretty gross, but that's the only way you know it's getting the job done. Congratulations to Dan for coming up with such an ingenious device.
