Investing the money and time in a DIY pest control solution could save you hundreds of dollars a year for each property. But is it worth the time investment?

DIY Pest Control is Becoming More Popular

Since the 1950’s, doing things yourself around the house has become more popular among landlords and property managers. To many landlords, DIY is a cheaper way of managing their real estate property. When BiggerPockets asked its members on who provides pest control services, the majority of them confirmed that it is their responsibility and not the tenants’ and they prefer doing it themselves through this ‘cheaper’ means.

Nowadays, with so many self-help resources and the sales of DIY Pest Control Kits, many landlords are carrying out home improvement and maintenance by themselves. Pest control such as spraying for bugs and rodent exclusion is no exception.

What types of DIY Pest Control Exist?

It is good to note that the most natural form of pest prevention and control is good hygiene. The problem is there’s only so much you can do to affect how clean your tenants keep the place. Unless it’s completely trashed and a health issue, you will need to focus on other methods to keep the pests under control.

Other than good hygiene practices, you can rid your home of pest through three major ways:

Chemical Pest Control

This is the control of pests using substances that destroy the pests, repels them or simply prevents them from coming into an area. It is the use of pesticides like insecticides, rodenticides, and acaricides. These can be directly applied on the pests or to the area where they can enter the home.

Biological Pest Control

This is less common than chemical control. In this case, you can use another organism that is a natural enemy of the pest to feed on them through series of actions such as predation and parasitism. The advantage of this is that the risk of poisoning is eliminated.

An example of this is bringing in cats to keep rodents under control, or introducing spiders to your property to help with flying insects.

Even though this can work, most landlords going the DIY pest control route simply choose chemicals because they’re easier to work with.

Physical Pest Control

This results from having a tightly sealed home. If it’s not properly sealed, your tenants are going to get a lot more visitors than they’d like. For example, older homes often left a gap between the top of the siding and roof. This gap is large enough for small rodents to get through. Installing rodent exclusion, such as a metal brace to close the gap, prevents the critters from getting in.

Also in properties with a crawl space and a raised floor you may consider putting up chicken/mesh wire around the side of the home to keep pests from living under the property.

Pros and Cons of DIY Pest Control vs. Calling the Pros


Professional: Though the cost of hiring an expert may be higher in the short run compared to when you do it on your own, it may pay off considerably after some years. Also, don’t discount the value of your own time. If it could be spent building more business or doing other things, there is something to be said for that as well.

DIY: This is cheaper in the short-run and cost being the major advantage over hiring an expert.

Of course, you won’t have to pay for the labor, but you will have to buy such items as insecticides, sprayers and a protective gear and suit.

In the long run, if DIY remedies are not well carried out the problem may become exacerbated. This allows the pests to fester and grow in number, causing more damage. This happens if the initial DIY measures that were employed did not tackle the root cause of the infestation.


Professional: The expert you hire has probably been doing this for years. He or she can easily detect what you can’t. Through the initial examination of your home, he or she will likely offer a much more informed solution that will address both the immediate and future needs.

Solutions offered will not only control the pest but also administer the solution within a reasonable time frame.

DIY: Usually is most effective if the area of infestation is smaller in scope. In the case of a bigger area, you may not be well equipped with the know-how of carrying out an examination of the infestation. This limits the reliability of your diagnosis  of the real issue. At this point, the process is done by guess work and errors are likely. So even though short term control may be achieved, long term control is less likely.

Safety and Management

Professional: The experts understand the pests, how they operate and how best to deal with them with them without jeopardizing the safety of the living situation in property. Pets, plants, food and humans all need to be taken into consideration. Professional extermination crews have practical experience on chemicals that are safe. The careful administration of these measures ensures that no harm is done to you or the home.

DIY:  There are many cheap DIY products and chemicals available in stores. If not properly administered, it could have negative health impacts on the residents, causing vomiting, rashes and even difficulty in breathing. Extra precaution should be taken before, during, and after the application of such chemicals.

Additionally, and without heavy consideration, are the legal implications of failing to properly administer any chemicals, especially if the residence is occupied.


Professional: Many pest control companies include warranties in their extermination policies, but you should ask before hiring them.

  • What kind of guarantee do they offer?
  • Will they come back for a free treatment in case the first extermination doesn’t eradicate the pests?
  • How do they handle the risks involved in the extermination process?

Questions like these will help put you more at ease if you know that the professional has policies that take care of these.

DIY: Your product may come with a warranty, depending on the store or the manufacturer. If the DIY pest control product does not come with a warranty, you will have to bear the consequences of the product application all alone. If anything goes wrong, you incur more cost and will have to deal with the damages further caused by these untamed pests.

Any DIY solutions are unlikely to be covered by any existing insurance policies regarding health hazards to residents. You should ensure that you’re covered or have a failsafe plan in place should you administer any chemicals that have detrimental effects to residents’ health.


Professional: From diagnostic services to actual treatment, experts do a thorough job by ensuring that the control services offered are based on careful examination of the situation.

The good news is that not every professional charges for diagnosis.  They give you a graphic view of the pests in your property and a control plan.

Also, another diagnostic is done after treatment to ensure that the control measure was effective as planned. With the range of services offered by the pest control expert, you are assured of a thorough job with maximum effect. Because the expert has done many other jobs, he or she knows exactly what to do from the first minute you make contact.

DIY: If you have no previous practical experience in pest control, you will need to depend on books, articles or even videos that explain and teach you how to go about the processes. You will have to learn on the job and adhere strictly to the safety precautions. This, of course, will not give you the top-notch effectiveness you need in dealing with those annoying pests.

With DIY pest control, you do a lot of guess work. If you are unlucky and your guess work isn’t fully effective, you end up spending more money, or end up with your property facing further damaged by these unwanted visitors.


Professional: When it comes to large pest infestations, a licensed exterminator will more than likely achieve a better and quicker result than when you handle it yourself, giving you the desired peace of mind and satisfaction.

DIY: There are many DIY Pest Control kits that promise a 100% satisfaction to users. But you should note that good satisfaction is not just about content. Usage and application determine a significant portion of the effectiveness.


If the infestation is huge and the situation is uncontrollable, you may need to think again on DIY pest control. You want to make sure the job is done right the first time, which usually involves hiring the pros.

But if the property is relatively pest-free and it’s just routine maintenance, DIY can be a great option to help you save a lot of money in the long run. Just be sure you’re not putting your residents at risk.
