Only by determining your preferences and requirements can you make the last decision. First of all, you need to understand some different kinds of the sprayer.

  • Handheld Sprayers

This type of sprayer often saves a lot of money for people. Also, it is a great option if you intend to spray occasionally. With its small capacity, you can carry the sprayer more easily without much attempt.

It often pressurizes air inside the tank until liquid is poured into it. When there is little liquid in its tank, you will have to pressurize more air. This means that more pumping is required.

  • Backpack Sprayers

After you pull the trigger, backpack sprayers will compress the air inside its tank and push liquid out. That’s how backpack sprayer works.

This allows you to control the pressure quite easily and efficiently. Backpack one is a good choice if you need to use the device on a daily or weekly basis.

  • Wheeled sprayers

Undoubtedly, when it comes to wheels, we will think of great mobility instantly. Wheeled sprayers are appropriate for those who manage a large area, such as fields or yards.

With a large capacity of liquid, you can apply it on big areas without having to recharge many times.

Overall, all types have their applications. But backpack sprayer seems to be a good choice if you need to use it every day or every week. Its pressure can be controlled easily, so it is suitable for you to spray for over 30 minutes daily.

You carry it on your back, so it is very mobile and versatile. Also, you might be concerned about a pull behind sprayers because they are very mobile as well.


Once you decide that you want a backpack sprayer to protect your plants from threats, it is time to consider several crucial factors that directly affect the performance of your working.


It will be very hard and tiring if you have to carry the sprayer back to charge its battery too regularly. The mobility is one of the best features of this type of sprayer. Do not turn it into the disadvantage.

Overall, the most popular types of backpack sprayer usually come with 4 gallons – a suitable amount to help you store much liquid for use. Of course, it is not necessarily suitable for you.

If your garden is small and you do not need to spray much at one time, it is possible to go for something smaller and more economical.

The weight of backpack sprayer is dependent on its tank size. Some people are eager to get bigger tank size but less willing to carry too strenuous sprayer. Therefore, you had better calculate carefully before making decisions.


Besides, many people seem to ignore the importance of nozzle. It is a big mistake because nozzles play an important role in the function of the whole sprayer. It is related to its flow rate, coverage and of course, applications.

You should look for some nozzles to meet different demands, instead of choosing one that fits all. Investment in nozzles is worth your money because it not only improves the quality of your sprayer but also prevents waste when you use it.

Spray Wand

If you do not have a good spray wand, the possibility is that the liquid might leak and cause danger to both you and your plants.

Therefore, getting a spray wand of high quality is a must to maximize the comfort and efficiency of your work.

On the other hand, the length of spray wand should be dependent on your arm size and your desired coverage.


To be durable over time, you should look for a tank made from high-density polyethylene. Also, it should be equipped with the ability of UV protection. It would be a perfect material for backpack sprayer.

Besides, you should be concerned about how easy it is to repair some parts of the sprayer, in case you need help. For example, pumps are very important, but they might face a lot of problems when you use them. So, make sure you can get help anytime it is necessary.


Some people are reluctant to use backpack sprayers because they are worried about its weight and how hard the work will be. Thus, comfort is a critical factor to consider before you waste too much energy in the garden.
