This 2-pack of the Classic Yellow 2.0 is the perfect gift for the serious fly hunter and includes a 90-day warranty & limited 1-year warranty with proof of purchase. BUG-A-SALT 2.0 is a unique, patented insect eradication device, which shoots a shotgun spray of regular table salt and decimates flies on contact. A surefire fun way to enjoy a disgusting task. Rid your house of all those pesky pests and have a blast while doing it. The 2.0 model is excellent for flies on windows or screens, and will not damage screens or furniture. This model is recommended for soft-bodied insects like common houseflies, mosquitos, pestilent/poisonous spiders, small to medium-sized roaches, and moths. For use by responsible people only. Do not shoot at pets, or humans. No house pets, butterflies, praying mantises, or the like are to be targeted with this device. Operating the BUG-A-SALT is very simple. Table salt is loaded into the hopper. You cock the gun by sliding the handle towards you. This will engage the pop-up sight (indicating it’s ready to fire). Slide the handle all the way forward, release the safety - and you are ready to aim, pull the trigger, & fire. Ordinary granulated table salt works best, sea salt tends to be too moist, and kosher salt is often too large to fit inside the barrel. Practice aiming by drawing a bullseye on a sheet of aluminum foil, place the target three feet away from the tip of the BUG-A-SALT, and aim for the center.
