Flow rate is seriously important. It’s going to dictate how effectively you use your chemical sprayer, but you don’t want a massive flow rate, either. You already know that chemicals can be extremely expensive, so you want a 0.4 or 0.5 flow rate to help you disperse it evenly across wherever it is you’re spraying, but anything over that, and you could be wasting product without even knowing it.
In accordance to that, you’ll also want to pay attention to the reach. Nobody wants chemical blowback to hit them in the face because of a minor wind. Certain units, like the Smith, can reach up to twenty feet away from the user, giving you more distance between harmful chemicals. This is especially useful if you have a diverse landscape, or you need to spray behind sheds or other hard-to-reach areas.
Our top pick is great, but the only thing it doesn’t have is a long handled spray nozzle. The long handle not only allows you to make good on the spray length, but helps you retain better control and grip. One hand on the reservoir, one hand on the spray nozzle, and you’ll feel like a professional pest control technician. Longer nozzles also tend to have accompanying components that maintain better pressure regulation, so you’ll spend less time pressurizing your tank and more time actually spraying.
Last but not least, look towards the reservoir capacity. If you have a large yard, something over an acre or so, you’re not exactly going to have a fun time with the simple one liter capacity of our top pick, the Solo. Instead, you might opt for something with a one-gallon tank to help you keep more chemicals on you, and spend less time refilling and pressurizing your tank. Capacity matters, but it’s the least important attribute.
