DIY Pest Control vs. Hiring a Pest Control Company: What’s the difference?

DIY Pest Control vs. Hiring a Pest Control Company- What’s the difference - feature

Why you should hire pest control experts in Sydney

Pests are unwanted guests in homes and offices. There are two ways to eradicate these creatures: do-it-yourself (DIY) or hire a professional pest control company.

DIY methods are a short-term solution and will not address the root of the problem. This is because commercially available pesticides are not strong enough to eliminate an entire population of, say, roaches. These creatures continue to multiply even after applying bug spray or pellets.

There is also the risk of using the wrong pesticide. Although information about these products can be found online, it might not be enough to ensure the safety of everyone in the building. Professional pest control companies are the better option for properties that have a severe infestation.

Here’s a deeper comparison between the two pest control methods.

Professional Experience for Pest Control Solutions

Choosing the right insecticide can be confusing. Although the label indicates what types of pests the product kills, it is crucial to follow the instructions to the letter.

A professionally trained pest technician will first survey the home and assess the root of the problem. Then they will recommend the best course of treatment. Finally, to prevent future infestations, they will propose repairs and other procedures to keep pests out.

Keep in mind that professional pest technicians have been doing these for years or even decades. They have handled all types of pests – from nuisance to destructive – including massive infestations.

Since this is their trade, they are always updated on the latest products and techniques for pest control. Whereas DIY methods are a trial-and-error exercise, professionals know exactly where to go, what to look for, and how to fix the problem.

Specialised Equipment

Professional fumigators have the right equipment, tools, and chemicals to eliminate pests from an entire building or community. Industrial-strength chemicals are more powerful than pesticides sold at hardware stores. In fact, they are so strong that most professionals ask the residents to vacate the home for a few hours until the fumes are cleared.

Compare the Cost of Pest Sprays

Picking up a bug spray at the local hardware may seem cheaper than hiring a pest control company. However, if the DIY method doesn’t work, then all those store-bought products will go to waste. Even worse, the pest infestation could result in widespread damage – leading to added expenses.

Having a professional carry out the work from the start means getting the job done right the first time – saving money in the long run.

Professional pest control treatments also ensure zero risk to the structure and human health.


Convenience is another important factor when choosing between DIY and professional pest control.

In the DIY method, the homeowner carries the burden of researching the types of pests, shopping for products, and applying the treatment.

On the other hand, a professional exterminator will handle everything right after they receive a job order. They will schedule an inspection of the home, recommend a treatment method, and show up at the allotted time period to get the job done.

However, it can also be difficult to have a pest exterminator working in the home while kids and pets are around or if the adults are working remotely. With DIY solutions, there is no need to wait for a tradesman – just stop by the local hardware store and apply the product anytime.


Chemicals always carry a risk, and applying them without proper knowledge can be harmful to humans, pets, and plants. Therefore, do not use a product without reading the instructions on the product label.

Professional pest technicians are trained to handle all types of chemicals. They have the proper knowledge and experience to keep the area safe while they work.

The DIY approach may be effective for minor pest problems, but it cannot handle a large-scale infestation. Furthermore, even if it does manage to make cockroaches, mosquitoes, and ants disappear, it won’t be able to provide a permanent solution. This is because these pests are adaptable creatures and can become immune to certain chemicals after some time.

On the other hand, a professional pest control company is required to provide a permanent solution for all your pest problems because it has a reputation to maintain. Negative reviews from dissatisfied customers can be bad for business. So, most of the time, the pest control crew will not leave the property until the problem is permanently fixed.

Good pest control companies will offer a warranty for their services. Feel free to ask questions about their policies, including details such as:

  • What type of treatment will be done?
  • Will they return if the issue is not solved?
  • Will they charge an extra fee if they have to come back?

When choosing between DIY pest control and hiring a pest control company, clearly, hiring a pro is a wise choice. The DIY approach may be cheaper, but it also comes with many risks, is less effective, and is time-consuming.

For nuisance pests such as silverfish, stink bugs, box elder bugs, bed bugs, or moles, a DIY job can be the easy way to go.

However, for dangerous and destructive pests such as ticks, fleas, mosquitoes, cockroaches, bees, termites, carpenter ants, rodents, and squirrels, it is best to call the professionals to permanently eliminate a continuing pest problem or large infestation.

Hiring a pest control company saves time, hassle, and even money in some cases.
