Mosquito Magician1 Gallon Liquid Concentrate with a 15L Pump Up Backpack Sprayer - User-Friendly - Ideal for Yards, Lawns, Patios - Kills Mosquitoes, Fleas, Fire Ants - with 6 Natural Essential Oils

Mosquito Magician is amazing!First, though, I'll start with one slight negative. The picture leads you to believe the sprayer is branded and/or specifically built for Mosquito Magician. It is a basic Chapin sprayer powered with a Black and Decker battery. That was a tad disappointing because I was hoping for a sprayer that had measuring tools designed to be used with their (included) solution. It wasn't enough to ruin my day though.Aside from that, it is a very easy to use system. Measure out the solution, mix with water, turn on the switch, squeeze the handle. It doesn't get more simple than that. And it 100% works. I live on an acre of riverfront land with vacant wooded lots adjoining mine. I was getting eaten alive by mosquitos. 2 hours after spraying this, I was and still am able to be outside in a T shirt without a single bite. I still see mosquitos here and there, but the difference between being bit several times just taking the trash out to being able to fully enjoy the outdoors without bug spray makes this 100% worth the investment. If you're on the fence (like I was) about whether to pay someone to spray or just do it yourself, do yourself a favor, buy this system and do it yourself. It's easy and cost effective!
