Best Chemical Sprayers Updated November 2018





Tree/Turf Pro Commercial, 4-Gallon
Check Price at: 1 store
This high-capacity backpack sprayer allows you to cover more ground with less effort.
This sprayer is made of high-quality materials and includes a 4-gallon tank, padded straps, a 3-stage filter, a constant pressure gauge, and a stainless steel wand.
It’s definitely heavy to strap on when it’s full. It requires some coordination, as you have to pump and spray simultaneously.


Lawn and Garden, 1-Gallon
Check Price at: 1 store
Choose Chapin if you’re looking for a long-lasting garden sprayer.
The twist-and-lock function is super smooth and easy to open and close.
Some customers wish for a finer mist. Always wear safety goggles and depressurize the sprayer before you open it. If not, you could get sprayed.


1-Gallon Bleach & Chemical, 15-Inch
Check Price at: 1 store
Another handheld sprayer you can use on lawns, gardens, decks, siding, and concrete.
The spray tip is very adjustable and you don’t have to pump it very much to get powerful pressure.
Instructions are confusing, but customer service is helpful. There isn’t a pressure release valve.


One-Hand Pressure, 1-Liter
Check Price at: 1 store
A smaller handheld sprayer with more bells and whistles than we expected.
This chemical sprayer features a drip guard for target treatment. It also comes with a locking trigger and pressure relief valve.
This is the smallest chemical sprayer on the list, but it may be all you need. Spray strength is adjustable, but the spray diameter isn’t.


Smith Contractor, 2-Gallon
Check Price at: 1 store
Contractors and homeowners love this commercial-grade chemical sprayer.
It has a long, 21-inch wand and 5 nozzles for spray adjustments. An in-line filter prevents clogs and the whole sprayer is easy to clean.
You’ll get your money’s worth with this chemical sprayer, but it’s not super durable.


Customer Reviews

It can be frustrating when weeds invade your otherwise perfectly manicured lawn. It’s equally disappointing when you can’t shake your edible garden of pests. A chemical sprayer may be just the thing you need to get the beautiful yard and fresh bounty you’ve worked hard on. Our team at House Method learned a lot while reviewing chemical sprayers. Did you know that chemical sprayers can be used for landscaping, washing, and painting? We’ll share all the details on the best chemical sprayers below.

Chemical sprayer reviews guide

Chemical or garden sprayers are a cost-effective alternative to hiring a landscaping company to spray your yard for invasive plants and pests. By taking on this task yourself, you have control over the herbicides and pesticides that you use in your yard and around your house.

In fact, you don’t even have to use harsh chemicals in a chemical sprayer. You can simply fill it with water and give your houseplants a good soak. You can also fill these sprayers with soap and water to clean siding or fill them with paint to stain a deck. Note: you don’t have to have a green thumb to use a sprayer. Most are actually quite versatile and easy to use.

Herbicides are chemical solutions that are used to kill invasive plants such as weeds. Look for vinegar-based products for a natural alternative to herbicide.”

Types of sprayers

Gas-powered chemical sprayers

These motorized sprayers have an engine that pumps the solution from the tank through the sprayer, eliminating the need to manually pump the machine.

  • Pros—These are arguably the easiest to use since you just point and spray—no manual pumping required. They usually include more attachments and accessories than other sprayers.
  • Cons—These heavy-duty sprayers are the most expensive. Not only do they emit fumes, but they’re also big and bulky. Fortunately, most gas-powered sprayers come on wheels.

Battery-powered chemical sprayers

Similar to gas-powered sprayers, battery-operated sprayers do the pumping for you, so you can focus your efforts on spraying.

  • Pros—They’re still easier to use than a manual pump sprayer and they’re available in a variety of types: handheld, backpack, and wheeled sprayers.
  • Cons—You’ll be limited to battery life and you’ll pay a higher price than a pump sprayer.

Pump chemical sprayers

Pump sprayers require you to regularly pump the solution during use. Pressure builds with each pump, so you can control how powerful your sprayer is.

  • Pros—You’ll have the most control with a manual pump garden sprayer. Without the weight of gas or a battery, these are the most portable sprayers. They’re also the most affordable.
  • Cons—Manual labor requires some coordination and can lead to fatigue.

Pesticides are chemical substances used to deter or kill insects that are harmful to plants. Some organic farmers use pyrethrin concentrate as a natural alternative to these harsh chemicals.”

3 Major factors to consider


Chemical sprayers are designed to be portable. There are several designs that make it easier to tote your sprayer around the yard, some of the most common being handheld, backpack, and wheeled.

Our top pick—Chapin Tree/Turf Four-Gallon Sprayer—is a great example of a backpack sprayer. It’s pretty comfy but kind of difficult to put on when it’s full. The remaining four featured products above are handheld sprayers. These range from small, one-handed sprayers like the Solo One-Liter Sprayer to two-gallon pumps like the D.B.Smith Contractor Two-Gallon Sprayer.

Gas-powered yard sprayers aren’t as portable. They’re big, bulky, and heavy. Fortunately, many models are on wheels, so you can tow them behind you.


Leaving chemicals in your sprayer for too long can lead to residue that damages your sprayer and your plants. Here’s how to keep your chemical sprayer in top condition.

  1. Empty the mixture immediately after each use. If you overfill your tank, you may have to spray your yard twice.
  2. Rinse the residue with detergent or ammonia (check your manufacturer’s manual to determine if herbicide or pesticide is recommended). You may let this cleaning solution sit in your sprayer overnight.
  3. Wash nozzles and attachments.
  4. Spray half a tank with hot, clean water. This will flush out stubborn residue.


You should take safety seriously when using harsh chemicals in your sprayer. Here are a few general guidelines to keep in mind:

  • Do your research before mixing chemicals.
  • Protect your skin by wearing long sleeves and pants.
  • Safety goggles and masks are highly recommended.
  • Depressurize your sprayer before opening it.
  • Don’t use a chemical sprayer around children or pets.
  • Remove any toys from the yard before spraying.
  • Avoid spraying on a windy day. Chemicals may reach untargeted plants or your neighbor’s yard.
  • Wash your hands and clothing immediately after using a chemical sprayer.
  • If you’ve sprayed your edible garden, wash your harvested fruits and vegetables thoroughly before consuming them.

Don’t dump chemicals on your yard, flowers, trash, or even down your drain. Refer to the manufacturer’s disposal recommendations or contact your local health or environmental department.”

Clever ways to use garden sprayers

You don’t have to use chemicals in a chemical sprayer. You can fill it with different types of cleaning solutions from diluted vinegar to degreaser.

  • Garden sprayers aren’t as powerful as pressure washers, but they are handy for rinsing off your car, siding, or driveway.
  • Cut through grease on just about anything with an engine.
  • Stain a fence or deck by attaching a paint filter on your spray wand.
  • Some homeowners have reportedly used garden sprayers inside their homes to shampoo their carpets.

Frequently asked questions

Are chemical sprayers safe?

If you fill your chemical sprayer with chemicals (i.e. herbicides and pesticides), you should take some safety precautions. Wear protective clothing and eyewear, spray away from children and pets, and wash your sprayer, hands, and clothes thoroughly after each use. Using natural cleaning solutions in your sprayer will decrease the health and environmental risks of using a garden sprayer at home.

How long should you stay off the grass after spraying pesticide?

Refer to the label for specifics, but most pesticide manufacturers recommend staying off treated grass for at least six hours. We recommend staying off your grass for 24–48 hours.

What precaution should be taken while using pesticides?

Pesticides may contaminate drinking water, food, and soil, and they’re most dangerous when inhaled, ingested, or exposed to the skin of both humans and animals. Always wear protective clothing when using your sprayer and clean the equipment after each use. You will find proper transportation, storage, and disposal instructions on pesticide packaging and labels, which should meet the World Health Organization’s requirements.

How long does it take for weeds to die after spraying?

You may be able to see a visible difference after spraying weeds with herbicides after only six hours, but it’ll take one to two weeks for them to die completely.

How do you dispose of pesticides?

Refer to your product’s label for disposal instructions. Never dump pesticides in your yard, trash, or drain. Call the product manufacturer or your local health or environmental agency if you’re unsure of how to properly dispose of pesticides.
