Chemical Spray: Buying 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—just 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.
You don’t have to have a green thumb to use a sprayer. Most are versatile and easy to use. To learn more about selecting a chemical sprayer, continue reading our guide below.
Types of Chemical Sprayers
There are a number of different types of chemical sprayers, each with their own benefits and drawbacks. Below are the different types of chemical sprayers:
Battery-Powered Chemical Sprayer
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.
Gas-Powered Chemical Sprayer
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 is 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.
Chemical Pump Sprayer
Pump-action 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.
Chemical Sprayer: Maintenance
Leaving chemicals in your sprayer for too long can lead to residue buildup that damages your sprayer and your plants. Here’s how to keep your chemical sprayer in top condition.
- Empty the mixture immediately after each use. If you overfill your tank, you may have to spray your yard twice.
- Rinse the residue with detergent or ammonia. You may let this cleaning solution sit in your sprayer overnight.
- Wash nozzles and attachments.
- Spray half a tank with hot, clean water. This will flush out stubborn residue.
Safety Measures In Spraying Chemicals
You should take safety measures when spraying harsh chemicals. Here are a few general guidelines to keep in mind:
- Do your research before mixing chemicals.
- Protect your skin by wearing work gloves, long sleeves, and pants.
- Personal safety gear and protective glasses are highly recommended.
- Depressurize your sprayer before opening it.
- Do not use a chemical sprayer around children or pets.
- Remove any toys and electronics from the yard before spraying.
- Adequately cover your hot tub, pond, pool, and any outdoor furniture prior to application.
- Avoid spraying on a windy day. Airborne chemicals may negatively affect untargeted areas by entering the home, water sources, and neighboring areas.
- 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.
How To Use A Chemical Sprayer
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 commercial degreasers.
- 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 apply deck paint by attaching a paint filter to your spray wand.
- Some homeowners have reportedly used garden sprayers inside their homes to shampoo their carpets.

Chemical Sprayers: FAQ
Below are some frequently asked questions about chemical sprayers:
Are chemical sprayers safe?
If you fill your chemical sprayer with chemicals (i.e. herbicides, insecticides, and pesticides), you should take extreme 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 precautions 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 (WHO) 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 will likely 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 the Environmental Protection Agency (EPA) if you’re unsure of how to properly dispose of pesticides.
