Top 5 Best Termite Sprays
If you’re in a hurry, you can click the links below for a quick look at the top five termite sprays we reviewed. For a more a comprehensive explanation (plus tons more information about in-home termite control), keep reading below.
What Chemical Kills Termites?
Though it may seem like these little guys are immortal, they do have their Achilles heel.
But among all the names of chemicals floating around, which are the best termite killer products out there?
Generally speaking, insecticides which kill termites specifically can be funneled into a class of their own called a termiticide. This is a blanket term covering the vast majority of chemicals which work to eradicate termites from an area–whether they live in soil or they’ve taken up residence in the woodwork of your home.
In addition to termiticides, a chemical called an insect growth regulator (or IGR, for short) is present in most all insecticides and gets the job done as well by stunting the growth hormones of the insect in the larval stage of life.
When you use a spray for termite control, you are buying a concentrated version of the termiticide that is mixed with water and sprayed into an area to then reach the termite colony, killing its members.
Why Use a Spray in the First Place?
With all the options available for taking out termites, what makes a spray the best bet?
Well, each type of insecticide has its merits and its pitfalls, but the sprays we reviewed are beneficial in the following ways:
- these sprays are mixed on a per-use basis, meaning the concentration can be adjusted based on need
- the liquid can seep into hard-to-reach places and kill off unsuspecting termites
- with a spray, you can a wider range of coverage than you would with a bait station
- the sprays offer residual protection against new infestations long after the termites (or other pests) in question have been eradicated.
Can’t I Just Use Vinegar to Get Rid of Termites?
In the world of pest control, vinegar is almost like liquid gold.
And yet, when it comes to termites, this is where vinegar’s powers fall flat—you’ll need something a little stronger to take out these ravenous insects.
In fact, termites actually produce a crude form of vinegar in their gut microbes. As their stomachs break down the wood and metabolize the cellulose within for nourishment, termites create acetic acid molecules (better known as vinegar), which they then use for energy.
So, essentially, if you douse your woodwork in vinegar in an effort to drive the termites out, you’re probably just fighting fire with fire.
Home Remedy for Termites in Wood vs Calling a Professional
If you’ve got termites on your property and want to get rid of them yourself, that’s understandable.
However, we recommend to go the DIY route only when you’ve got termites in your soil or in trees or bushes in your yard rather than infesting the wooden structures of your actual home.
Well, once termites invade your home, you’re outnumbered. Even if you have a full house, the termites will still have you beat–even the smallest termite colonies fall in the 50,000 member range!
Once they’re in, they’re really in–setting to work chomping down on your hard-earned property. In the soil, it’s relatively simple to spray a chemical to eradicate the termites, but the properties of wood make it so that it the chemicals dry out and distribute without as much ease.
Termites typically infest a home in either one of two ways, depending on the type of termite:
- by way of tubes the color of wet sand that snake up the walls of basements into crawl spaces (subterranean termites)
- by burrowing into furniture (drywood termites)
If you spot these safety tubes or notice drywood termite bite marks in your woodwork, it may be too late for home remedies to get rid of your termite problems.
Take our word for it–with a destructive pest like termites, biting the bullet and shelling out for a high-quality product or termite control service will pay for itself in the long run.
Are These Indoor Termite Sprays?
One of the most common questions on consumers’ minds is whether most termite control sprays can be used both indoors and outdoors.
We get it: you want something that’s strong enough to combat the elements outside, but gentle enough not to affect your pets and kids indoors.
The good news is that most sprays sold to consumers in a retail setting (both online and in stores) are versatile in the sense that they can be flipped for whatever you need; either indoor protection against termites or an outdoor safeguard as well.
What Should I Keep In Mind When Shopping For Sprays?
Keep this in mind: just because all sprays are marketed to kill termites means they’re the same. Here are a few things to consider when you’re making your selection.
- Do you have other pests in your yard that you need to kill as well?
- Are there any standing bodies of water on your property?
- Do you grow any of your own food in the yard? If so, will you be spraying these crops?
Below are some of the factors to consider before purchasing anything.
Most termite killer sprays are sold as industrial bottles and require a spray nozzle to administer the liquid in your yard or home.
The spray nozzle spreads the liquid evenly throughout an area, and it allows the chemical to seep down into the soil to further distribute with existing moisture from rainwater.
A huge bonus of the spray nozzles is their utility: not only can this sprayer be used to distribute termiticide through your home or garden, but can be thoroughly cleaned out and used to spray fertilizer or herbicide as well. We recommend something like this.
Your Family and Household Members
If you’re single, or maybe a household of two adults, this section may be a simple shrug of the shoulders to you.
But if you’ve got a baby learning to crawl in one room, a toddler tinkering around in another, a dog chasing his tail in the front yard and a cat snoozing in the corner, you may be wary about firing off a chemical through your home, no matter how non-toxic it claims to be.
It’s important to learn about some of the major termiticides and insecticides so that you can make a decision as an informed consumer, rather than just grabbing something from a shelf or an Amazon lineup.
- Bifenthrin–pyrethroid extract which occurs naturally and stops an insect’s nerve cells from working properly, causing death
- Permethrin–natural extract from the chrysanthemum flower which paralyzes insects and leads to death
- Fipronil–a powder which kills insects by binding to nerve endings and shutting down the nervous system
- Imidacloprid–a nicotine-mimicking insecticide which kills the nerves and shocks insects to death
Will These Insecticides Hurt Me?
It’s natural to wonder whether your nerve endings will also meet their untimely demise if you use a termite spray with one of these ingredients, but don’t fret!
These sprays work their magic on termites because their bodies are so small. A human would have to gulp down more than their fair share of termiticide to have any ill effects.
That being said, please exercise caution if you do have young children in the house. Always use your best judgment and keep chemicals out of reach of kids. If any chemical is ingested, please contact Poison Control immediately.
Also, make sure to use proper Personal Protective Equipment (PPE) while spraying your yard and garden for termites. To get an idea of what we’re talking about, check out the information in the video below.
Termite Sprays Reviewed
In the below section we break down each of our product recommendations in a little more detail.
Bora Care is a product that has a specific niche in taking care of termites. It comes in the form of gallon jugs, and its cost lands in the mid to almost low price range for pesticides.
Of course, the trade-off here is that it treats several wood destroying insects; most forms of termites that you will find here in America. Now, this is a little bit more old school than modern pesticides as it is a Borate, which is a derivative of boric acid.
Most people have to deal with termites at some point, and boric acid has been shown to be very effective over the years. This product makes the list if you are looking for a way to cut cost on a pre-construction termite treatment or going to do a post-construction termite treatment for subterranean termites.
The one criticism I was able to find is that this product is very thick, almost like honey, and it may be a little difficult to work with at first. Some of the customer reviews suggested mixing it with water. I advise reading the label first to make sure that this is something that won’t reduce the effectiveness of the treatment.
The Good And The Bad
- Moderately priced.
- Borate based.
- It can be used in pre-construction or post-construction projects.
- The formulation is thick and can be difficult to work with due to the viscosity of the product.
Normally, the first name to come up at the mention of termiticides is Talstar. It’s the most widely-acclaimed, well-known termite spray out there, and for good reason.
It certainly gets the job done, killing termites as well as other insects that get in the way. It’s convenient, requiring only an extra spray nozzle to administer the liquid out into the yard. It contains a high level of Bifenthrin, but not so high that it can’t be used inside.
So, why don’t we list this as our top pick?
Simply put: it’s too expensive. You’re paying for the brand, but you really don’t have to. We can’t deny that it’s a wonderful product that has its merits, but the same product can be purchased for a lower cost.
The Good And The Bad
- Stands up to sunlight and heat
- It adheres to insects easily
- Can be expensive
- Has a smell
Martin's IGR Concentrate
If you’re working with a tight billfold, this is the product for you.
Not only is Martin’s IGR Concentrate the economical option when you’re doing your initial shopping, but it begins to pay for itself: IGR stands for Insect Growth Regulator.
This means that instead of killing just termites, it stops all insects in their tracks…literally. Pests’ growth hormones are inhibited in the larval stage, meaning that new bugs can’t pop up and, well, bug you.
This spray is suited for mostly indoor use–which we really like–because you can protect your home from a potential termite infestation before it happens.
While you’re at it, you can kill off any other bugs that may be lurking around, whether you know you have them…or not.
The Good And The Bad
- Appropriate for indoor use
- Strong enough to be mixed for outdoor use as well
- Affordable option for those who need to save a few bucks
- Kills more pests than just termites
- Does not include sprayer
- The bottle comes in a 4 oz container, which may be too small for some consumers
Eco Friendly Living Essentria IC3 Pro Insect Killer
Essentria IC3 Pro Insect Killer is an awesome alternative to those who want an all-natural and botanical answer to their termite problem.
The solution is compliant to EPA standards as a botanical insecticide, and passes the EPA’s Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 25(b) exemptions.
In addition, Essentria IC3 Pro Insect Killer complies with the standards of the National Organics Program.
We recommend this product not only for consumers who want to take a more natural approach to knocking out termites in the garden, but for those who have standing water.
If you have a pond, a pool, or access to a creek anywhere on your property, it’s imperative that you use a product that’s not quite as harsh, chemically speaking.
The last thing you want is for a ton of chemicals to build up and grow stagnant in your pond while termites run free, escaping into your home.
The Good And The Bad
- Professional-grade product that kills termites and other pests
- EPA-compliant to kill bugs without harsh chemicals
- Exempt from FIFRA 25(b)
- Great for all landscape types
- Some previous customers noted a strong minty odor
- Reportedly killed some users' outdoor plants
- Requires a spray nozzle sold separately
