Pest Control Spraying

For pest control, possessing a powerful and well-built pressure sprayer is a necessity if you wish to apply the chemicals where they can truly make a difference, such as cracks and crevices. In fact, there is an entire science in and of itself dedicated to pressure sprayers for insecticides. A good sprayer can make or break pest control applications.

Garden and Lawn Maintenance Use

But it isn’t just pest control spraying that benefits from good spraying equipment, weed maintenance in lawns and gardens also requires a pressurized spraying application to stand out as an effective weed sprayer. Garden sprayers can serve many purposes in both the realm of pest control as well as regular lawn and weed maintenance.

Professional Pressure Sprayers

When determining what sprayer will get the job done in a thorough and effective manner, a professional-grade sprayer may be your best bet. Spraying insecticide can have its advantages, in that you are delivering a more concentrated dose of poison to your pests. The chemicals have a stronger chance of killing the insects in the area, but there are drawbacks to using a smaller or aerosol spray.

Aerosol sprays tend to cover a smaller area than what you can achieve with professional sprayers, which means you have to use more aerosol sprays to achieve consistent results. Aerosol sprays can also prove more harmful to yourself and others, as you are having to rapidly spray a concentrated dose of poison in areas where other people and pets have to live and eat. Depending on the formula, sprays also have a better chance (albeit a small one) of getting onto surfaces, and are generally only effective soon after they are applied.

As you can probably tell, they aren’t nearly as effective as other methods. Many places that spray will do so at certain times of day, hoping to catch as many insects still in the air as they can. This doesn’t do anything for insects, such as bed bugs, that are hiding in cracks and crevices or that are missed by the initial spraying. It also doesn’t help with the airborne insects that professional sprayers can catch.

Sprays are great for their higher fatality rate, but the time involved with laying down a good coating of spray can be both costly and tedious, which is why this article will present five of the best pesticide sprayers.

Battery Operated and Hand Pressure Sprayers

Professional sprayers certainly work to address all of your pest control or herbicidal needs, but battery powered sprayers can increase the output of traditional sprayers substantially. 

Battery operated sprayers (hand pumps, hand cans, and backpacks) are designed for spot treatment and for spraying smaller areas such as tree seedlings, small lawns, or flower beds not suitable for professional sprayers.

As is true for all sprayers used for the application of chemicals, application accuracy with battery powered and hand pressure sprayers are affected by travel speed, nozzle type, and spray pressure. 

Uniform distribution of sprays can be difficult even with training and regular calibration. The importance of application accuracy must be applied to all spraying equipment types, including Battery powered and hand powered sprayers.

Always remember to maintain a uniform walking speed, which is essential to keeping the application rate relatively uniform throughout the operation. A higher travel speed will result in a lower application rate. Maintaining a uniform spraying pressure is also essential both for keeping the application rate and the droplet size uniform during the application. Lowering the spraying pressure leads to higher application rates, and larger droplets.

It also helps to maintain the optimum spraying distance between the nozzle and the target. This will help prevent oversaturation of an area with product. Battery powered sprayers are ideal for doing most of the spraying work for you, and for added benefit, you can consider a rechargeable battery powered garden sprayer to make the process easily repeatable without constant battery replacement.

How to use a garden pressure sprayer

Now you have selected your pressure sprayer of choice, the next step is understanding exactly how to use it. All sprayers are pretty universal in their actions, so the first step would be to remove the tank lid and close down any applicable valves to avoid product splatter. You may also want to wear gloves and a respirator mask if you are working with chemicals.

Next, you will want to fill the tank with the required water and chemical ratio depending on the type of chemical you are using. You will also want to make sure that you adequately measure the amount of area you wish to cover and multiply accordingly based upon the chemical instructions. Then, close the lid and begin pumping to aggregate the mixture for maximum potency.

Next, you can begin to adjust the applicable nozzle to reach the desired amount of spray coverage you require. For pest control, this is usually measured in square footage and most chemicals will cover anywhere from 1,000 to 2,000 square feet of coverage. The key to spraying is to adjust the nozzle accordingly based upon the task you are performing. For plants, this can be a wide spray dimension and for pest control, narrow is usually better in order to get into cracks and crevices.

Once finished, you are ready to clean.

Cleaning and maintenance

Cleaning a garden sprayer is also fairly universal across any model. The first thing you will want to do is to thoroughly rinse the tank reservoir to remove any chemical residue, which if left uncleaned can cause equipment and filter clogs. 

Additionally, you may want to soak all the applicators and even the tank in warm soapy water to increase the loosening of built-up chemicals.

For stainless steel sprayers, you can follow this method as well, but you will want to thoroughly allow the sprayer to dry to prevent any rust from forming. Also, it is a good idea to polish any stainless steel products to prevent calcium deposits. 

The most important thing to remember when cleaning sprayers is to completely remove the chemical residue from all components of the sprayer. This is crucial to prevent equipment malfunction. 

For battery operated sprayers, take extra care to avoid wetting any of the electrical components of the sprayer. So, basically, soap, warm water, rinsing, and drying are the key components to cleaning any garden sprayer.

What to look for when buying

All of the above mentioned products are great additions to consider when surveying the various types of garden sprayers. Some things to keep in mind are how large of an area you need to spray and how often you will need to spray. 

A professional sprayer is a great product to invest in, but if you only have a tiny area to cover, a handheld pressure sprayer would be a more efficient purchase.

Additionally, warranties are always a great thing when investing in any type of equipment. Some companies offer them and others don’t. If you are paying for an expensive product, a warranty could very well be a possible selling point to consider. The above products have been thoroughly vetted and reviewed to make this process easy for you.

How far will they spray? What's the distance?

Pump sprayers can range in diameter in how far their spray reaches. Although, it isn’t always important to consider how far a sprayer can reach, but more so how efficient a sprayer is in administering a chemical. Most sprayers can reach upwards of 10-20 feet in spray reach. A far spray reach is important for areas that are hidden or obstructed in pest control.

For weed spraying, the distance a spray can reach is not as important as how thorough the sprayer is in administering the chemical. With that being said, the further a sprayer can reach, the less distance you will have to travel to administer the chemical. So, 10-20 feet is a good consistency to remember with garden sprayers.

Buyer’s Guide to Garden Sprayers

Product Volume:

The tank is usually the most important aspect of a garden sprayer across any sub-type. The more volume capacity of the sprayer, the longer and easier the job will be. If you have a comprehensive spraying job ahead of you, definitely go with a model that has a large gallon capacity, but if you only need to do spot treatments or watering, a handheld sprayer is certainly applicable.


There are thousands of off-brand sprayers on the retail market and nearly all of these types of sprayers are made from cheap and easily degraded material. Invest in a model of sprayer that is made from durable and quality materials. The higher the quality, the better and longer the performance.


In addition to the tank, the nozzles and applicators of a sprayer are the next most important component to consider before purchase. A wide array of nozzles is always a good sign, as this will allow you to administer chemicals in a wide variety of geometrical circumstances.


Utilizing a sprayer can take time, which means it is also important to remember the comfort level of maneuvering with the sprayer. Backpack sprayers have this aspect nailed by allowing the equipment to be mounted to the back and shoulder, which eases any discomfort in these areas.

The Bottom Line:

Garden sprayers compose a wide variety in the insecticide and herbicide market, with so many different varieties, some guidance is needed to make sense of the types and their uses. 

Professional sprayers are always a good choice and are pretty universal in their methodologies. 

Battery powered sprayers take the concepts of professional sprayers to the next level, by allowing you to allow the sprayer to take control and do most of the work.

Handheld pressure sprayers are also worth mentioning, since these are sometimes all that is needed for small projects. 

This market is comprehensive and these selected reviews will help you in not only deciding what sprayer is best for you, but also how to use sprayers for all of your pest control and lawn and garden needs.
