Can I apply Termidor SC myself?

Yes, Termidor SC is labeled for homeowner (DIY) use, so you can perform your own termite or ant treatment without hiring a professional.

Many customers successfully complete a full perimeter termite treatment themselves by following proper application guidelines. A standard trench-and-treat application around your home’s foundation can eliminate active termites and provide long-lasting protection, often up to 7+ years when applied correctly.

DIY treatment can be cost-effective, but it’s important to follow label directions carefully.

When is the best time to apply Termidor SC Insecticide?

Termidor SC can be applied at any time of year when pests are active, and the ground is not frozen.

For best results:

• Apply during dry weather conditions
• Choose a time when no rain is expected for at least 24–36 hours after application

This allows the product to properly bond to the soil, which is critical for long-term effectiveness.

How much Termidor SC do I need for my home?

The amount of Termidor SC you need depends on the size of your structure and the linear footage of the foundation.

For termite trench treatments, the standard application rate is:

• 4 gallons of finished solution per 10 linear feet of trench

To estimate:

1. Measure the total linear feet around your home’s foundation.
2. Divide by 10 to determine how many sections you’ll treat.
3. Multiply by 4 gallons per section.

Each gallon of finished solution requires 0.80 fl oz of Termidor SC, so you can calculate how much concentrate you’ll need based on the total gallons.

For example:

• A typical 2,500–3,000 sq ft home may require 100–150 gallons of finished solution, depending on layout and construction type.

For step-by-step guidance, follow a full trenching and treatment process to ensure you target termites at their entry points in the soil.

What is the correct mixing rate for Termidor SC Insecticide?

For most termite and ant applications, mix:

• 0.80 fl oz of Termidor SC per 1 gallon of water
• This creates a 0.06% solution, the standard labeled concentration

The bottle includes a built-in measuring reservoir to make accurate mixing easy.

Always mix only what you plan to use that day, and agitate the solution before and during application for best results.

How does Termidor SC eliminate termites?

Advanced undetectable technology
Termidor is made from a revolutionary new non-repellent or "undetectable" chemical technology treatment. That means termites cannot see, smell, taste, or avoid Termidor. Instead, they contact, ingest, and share it with their nestmates. This is in sharp contrast to older liquid termite controls, which rely on repellent barriers that termites can find breaks in or avoid completely.

The "Transfer Effect"
Termites that contact Termidor transfer it to every other termite they in turn contact, in a unique process called the "Transfer Effect." And because Termidor is engineered to be slow-acting, termites have ample time to spread it throughout their entire termite population.

Better than bait... without the wait
Baits can take years to control a termite colony. Termidor begins working immediately to wipe out termites inside and immediately surrounding your home. Termidor is the most effective and fastest at completely eliminating termite populations--up to six times faster than bait.

Does Termidor SC Termiticide only kill existing termites, or does it prevent future infestations?

Termidor SC does both.

• Eliminates active termite infestations
• Prevents new colonies from entering your home

When applied as a complete soil treatment, it creates a protective barrier that can last up to 7 years, helping safeguard your structure long-term.
 

Can rain affect Termidor SC after application?

Yes, rain can impact performance if it occurs too soon after application.

Termidor SC binds tightly to soil, but it needs time to “set.” If rain occurs before it has bonded properly, it can reduce effectiveness.

Best practice:

• Wait until you have a clear weather window
• Ensure 24-36 hours of dry conditions after application

Once bonded, Termidor SC is highly resistant to breakdown from normal rainfall.

Termidor for Ant Control:

Chances are that the ants in your house actually have their nest outside, where they travel back and forth for food and water. So, since they live outside, it makes sense to control them there. Termidor SC can be applied above ground to the exterior foundation walls of your house, creating a treated area of protection for excellent ant control.

Unlike older insecticides, Termidor can't be smelled, tasted, or even felt by ants. So they crawl through the treated area, not knowing that by ingesting treated materials or merely contacting the insecticide, they'll die.

Termidor is unique because ants not directly exposed to the Termidor-treated area will be controlled as they come into contact with affected ants. This Transfer Effect means you'll see its effects on ants in one to three days, and most species will be controlled within the first week following the treatment.

Termidor for Carpenter Ants

Many people ask us if Termidor SC can be used to treat Carpenter Ants. The answer is yes. Termidor SC is one of the most effective products on the market today for treating Carpenter Ants.

• Termidor SC may take up to 90 days to kill termites, depending on the colony size.

Termidor SC Application Instructions

1. For Termite Control: To protect your home from future termite infestations, Termidor must be mixed with water and poured in a 6-inch deep trench that is dug around the foundation of the home. Please read below for more information.
2. For Control of Ants and other Target Pests: Termidor is mixed at a rate of .80 fl oz. to one gallon of water in a pump sprayer and sprayed around the outside foundation of the home. For example, you would spray 1 foot up the foundation of your home, and 1 foot out onto the ground.  The treatment will last about 4-6  months, and will then need to be reapplied.

For Termite Control, each 20 oz. bottle will make 24 gallons of solution and treats 60 lineal feet of trenching. For termite pre-treatment use 1 gallon of finished solution per 10 sq. ft.  For ant and general insect control, each 20 oz. bottle will make about 24 gallons of diluted solution and will treat approximately 16,600 sq. ft. (You will need to use approximately 1.5 gal of diluted solution per 1,000 sq. ft.)

Standard Application Dilution Rates / Mixing Rations for Termidor SC:

 * For Termite control, mix at a rate of 0.80 fl. oz. for each gallon of water used.

 * For ant and general insect control around the exterior of a structure, the mix rate is 0.80 fl. oz. per gallon of water.

How much Termidor should I buy?

• One 20 oz. bottle of Termidor will make 24 gallons of finished solution and will treat approx. 60 lineal feet around your home for a termite treatment.

• Use 4 gallons of finished solution per 10 lineal feet around the house.

Example: A home with 200 lineal feet around the foundation would require 4 bottles of Termidor. Most homes require at least 4 bottles.

Termidor SC is for use in the following areas:

Outside surfaces and along foundation of Residential, institutional, commercial and industrial buildings and utility enclosures; wall voids of listed structures; NOT for indoor use; for pre-construction and post-construction treatment for termites, including concrete structures such as patios, porches, sidewalks and foundation slabs; concrete slab (including monolithic, floating and supported concrete slabs) on ground or in basements; hollow block foundations or voids in masonry; structures with French drains and sump pumps; basement structures; crawl spaces; around bath traps and shower drains; posts, poles, and wood landscape ornamentation

Indoors

• Termidor SC is for Outdoor use only. Indoor spraying is limited to spot treatments for live termite infestations. The product cannot be used indoors for ant or pest control.

Outdoors

Termite Control – See How to Do a Termite Treatment

Termidor is most often used as an in-ground treatment, where it is mixed and then poured in a trench around a house to create a barrier against future termite infestations. However, the product can also be applied to live termite infestations as a liquid spray, liquid dilution, or as a foam application.

A professional company that would come and treat your house with Termidor would usually have either a 50-gallon or 100-gallon spray rig on the back of their truck, with a hammer drill for drilling holes in your garage concrete slab, if you have one, and slabs around your house like porches and patios. Commercial rental places, such as United Rentals, may have these products.

Most homeowners who apply Termidor themselves use a 5-gallon bucket. It takes longer because you can only mix 5 gallons at a time, but it gets the job done. You should apply 4 gallons of Termidor every 10 lineal feet around the foundation of your home. Homeowners can estimate 4 gallons by using a 5-gallon bucket and only filling the bucket most of the way full. You will need to dig a small trench against the foundation of the home about 6 inches deep and 6 inches wide, into which you will pour the finished solution and mix it with the soil. It is also important to treat the backfill, which is the dirt that you took out of the trench lying next to it. If you just put this dirt back untreated, the termites could go through this untreated section and not be affected. You should either push the dirt back in right away to mix with the 4 gallons you put in the trench, or take a one-gallon sprayer and soak the backfill dirt down before pushing it back in the trench. This will create a termite-proof barrier around your home that will last up to 10 years. Please read the label carefully when applying Termidor, as it will give more detailed instructions and precautions.
