Do Termite Sprays Work?

It all depends on the formula of the termite spray you’re using. Each commercial spray that you’ll find in the market has its active ingredient.

Most of the time, these are Insect Growth Regulators (IGRs). What it does is it stunts the growth of the termites in the larva phase. This will stop the growth of the colony and eradicate the entire population at some point.

Aside from IGRs, termite sprays are also blended with termiticides that kill the pest upon contact. These are termiticide concentrates mixed with water to achieve a safe and household-friendly level of potency.

Back in 2000, the Environmental Protection Agency (EPA) banned the use of Dursban, a popular household insecticide during that time. It was found that continuous exposure to this chemical will result in neurological risks in children. It was discovered to have contaminated edible vegetation.

Is Vinegar Enough?

When it comes to pest control, vinegar is liquid gold. It can kill bugs, spiders, ants, and a myriad of other insects. However, when it comes to termites, you need something way potent. Although it can kill the colony members upon contact, it has very little to no residual effect.

Countless re-application is necessary to make a dent on the termite population. The biggest consolation here is that vinegar is non-toxic.

Also, many termite species produce acetic molecules in the process of digesting wood. Since acetic acid is a component of vinegar, many termites can survive the bombardment of the DIY pesticide.


As much as commercial termite sprays aren’t as potent as the termiticides pest control companies use, it’s essential to take some precautions. Continuous exposure to this chemical, even in small amounts, can lead to irritations and complications for those with underlying conditions.

Based on the World Health Organization guidelines, the safe use of pesticides should include the following:

➡️ Storage And Transport

The pesticide/termiticide should be locked away from children and any unauthorized users. Also, it should be stored in a place where it won’t be mistaken for a drink or food. Moreover, the pesticide should be stored away from heat and direct sunlight.

➡️ Labeling

Always keep the pesticide in its original container, complete with an English label. Also, you should purchase an insecticide with a complete guide in case someone swallows or got exposed to the chemical.

➡️ Disposal

If you’re disposing of an expired termite spray or any pesticide, it should be poured on a dug hole in the ground. Make sure that it’s not going to be in contact with any water drain or source. Pouring the termiticide on the drain isn’t advisable. Also, never throw a termite spray in an open fire.

Additional Safety Tips

In this post, James from DoYourOwnPestControl gives us more tips for safe handling of pesticides:

Aside from the guidelines of WHO, you should always wear protective gears like masks, gloves, and protective eye wear. If any part of your body parts got in contact with the spray, wash it thoroughly with flowing water.

If your eyes, nose, or mouth got exposed, it’s best to consult a physician right away. This is even more pressing when it comes to kids.

Also, avoid applying termite sprays on food preparation areas. If someone in your family experienced adverse reactions upon the application of the spray, discontinue usage.

Benefits Of Using Termite Sprays

Setting aside some minor downsides, termite sprays help homeowners manage the infestation. As long as the termite population is still small, termite sprays can help eradicate the entire colony.

Here are some benefits of responsible use of termite sprays:

➡️ It Can Really Kill Termites

If applied on the actual harborage of the pest, these sprays can really kill a portion of the colony. The diluted termiticide can seep through wood surfaces and get into the pest.

➡️ It Has A Residual Effect

Commercial termite sprays offer a residual effect that can last for days or even weeks. This means that the active ingredient continues to kill termites upon contact. Long after the colony is eradicated, you can use termite sprays to shield your home against another infestation.

➡️ It Comes In Various Concentrations

Depending on the formula, termite sprays can be used daily or on a weekly basis. It’s important to check the concentration level of the pesticide. In addition, this will allow you to treat the infested area in just a few applications.

➡️ It’s Affordable

Unlike professional treatments, termite sprays offer a cheap solution to minor termite infestations. Also, it’s very easy to apply since it already comes with a nozzle or a spray hose.

When To Call A Professional Exterminator?

If termites are already infesting a big part of your home, termite sprays alone can’t fix the problem. It’s best to invest in a professional treatment to ensure that all the pests will be eradicated.

Take note that only licensed exterminators can handle and procure potent termiticides. These professionals know the proper application and precautions needed to ensure that the treatment will be safe and efficient at the same time.

Also, it’s best to consider the best termite spray as complementary protection against the pest.

What To Consider Before Purchasing?

If you’re planning to purchase a termite spray, always consider the following points first:

➡️ Spray Construction

Application is crucial when it comes to termite sprays. With this, you should look for a spray construction that’s easy to use.

I recommend an adjustable nozzle that will provide a variable spraying power. If you’re purchasing an aerosol version, make sure that the can has enough pressure to eject the termiticides properly. Also, opt for one that sprays in a concentrated trajectory.

➡️ Active Ingredients

Termite sprays come with different active ingredients. Each of these kills termites in different ways. Deltamethrin is the most common active ingredients in most termite sprays that you can purchase from home supplies stores.

Deltamethrin belongs to the pyrethroid family. It’s a synthetic version of pyrethrin commonly used as treatments for lawns, golf courses, and other outdoor areas. In pure form, Deltamethrin is colorless and odorless. To prevent Deltamethrin from being mistaken as a drink, pesticide manufacturers blend it with various scents. Termite sprays with Deltamethrin come in orange, cedar, and other scents.

Deltamethrin is a potent insecticide that can kill a variety of insects. Furthermore, it can be formulated in aerosols, granules, dust, and more.

How Deltamethrin Works?

When a termite gets in contact (or eats) with the substance, it will target their nervous system. The toxicity will kill the pest. Anyway, Deltamethrin is perceived to be less dangerous to mammals due to their bigger size, higher body temperature, and lower chemical sensitivity.

Still, you should practice caution when applying Deltamethrin-based sprays. Chronic exposure to this chemical can lead to numbness, itching, burning, and even muscle twitches. These symptoms should go away within 48 hours unless the person has an underlying condition.

Another active ingredient used in termite sprays is cyfluthrin, another pyrethroid.

➡️ Allergies Of The Occupants

Before you apply or purchase a termite spray, make sure that no one in your family is allergic to the active ingredient. As mentioned above, Deltamethrin is the most common ingredient of over-the-counter termite sprays. Exposure to this could lead to skin and respiratory irritations.

An acute allergic reaction may lead to swelling of the face, lips, and eyelids. In rare cases, it can cause tachycardia, bronchospasm, epigastric pain, and nausea.

If someone has a history of adverse reactions to synthetic chemicals, you can opt for a natural formula. Below, I have reviewed a Bonide Termite and Carpenter ant killer which consists of natural ingredients that are non-toxic and non-staining.

➡️ Pet Safety

Aside from securing your family, you should also consider the welfare of your furry friends. Deltamethrin is relatively safe, but you should avoid using it in areas where your dog or stays. Exposure to termite sprays may lead your pet to experience excessive drooling, muscle tremors, vomiting, and incoordination.

If your pet exhibits these symptoms after the application of the pesticide, it’s best to send it to the vet right away.

➡️ Residual Effect

The residual effects of the termite sprays give continuous termite-killing effect on your home. Also, it will shield the treated area from another infestation within a specific period.

Usually, the best termite spray will have a residual effect of 4 weeks or more. If used outdoors, the residual effect could be shorter since rain and outdoor elements will wash out the chemicals.
