Termidor SC Termiticide/Insecticide - Questions & Answers

If stored in a cool dry area, Termidor will last 3-5 years. You want to be sure to use any mixed solutions within 24 hours of mixing. Termidor is meant to be applied indoors as spot treatment only. It is recommended to perform the same 6inx6in trench in the crawspace as around the outside perimeter. Was the solution is applied into the trench it will bond with the soil and last up to ten years. You may want to consider if possible injecting a foam like Alpine Foam into the areas where you have seen the drywood termites. Please visit our guides and tips for Termite control.

Termidor SC is only labeled to applied indoors as a spot treatment. The application you are describing is off label. Please contact BASF for further assistance.

When it comes to termites, you should never wait as there is never a best time.  Especially if you are worried about activity.  Having said that the dryer the soil the better for Termidor SC when you are using it as a prevention in a trench around the perimeter of the home.  Termidor SC is made to bond to the soil, and the less moisture in the ground, the easier it is for it to take hold and provide long lasting protection.  The only temperature that effects Termidor SC is when it is below freezing.  We recommend reading our 'How to Perform A Termite Treatment'article. It offers information on application, tools needed, product recommendations and other instructions.

Termidor SC and Dominion 2L are both labeled for subterranean termites and will effectively kill them. The main difference between the two is the active ingredient and the amount of time it stays in the soil. Termidor SC will last about 10 years in the soil, while Dominion 2L will last about 5 years.

It is very possible that there may have been a colony there at one time, or that it has moved somewhere else in the structure. You want to contact an exterminating company in your area to do an inspection. Normally, no charge. They will be able to tell you if you have termites and what species. Once we know, we can make an effective treatment plan.

While we cannot comment on the work or word of a professional, one benefit of having a company treat your home is they do provide a warranty.  What that warranty is would need to be asked of the company and any contract they may have had with you.  While Termidor SC can last in the soil for 10 years or more, it does not guarantee you won't have termites for 10 years.  The 10 year applies to the areas that you apply Termidor, it is guaranteed to stay where you put it and protect and last for 10 years. However, no termite treatment can 100% guarantee that you won't have termites because termites can enter your home in places that you cannot treat, like underneath a slab, through a plumbing pipe, or through an area you cannot get the treatment to because it is covered or inaccessible. If any of the soil was disturbed, a retreatment may need to be done.  After your home is built, it is impossible to get to every entry point.  There are always areas you cannot get to which is why you should continue to have a professional company come out every couple of years to do a professional inspection to make sure you have no areas of activity. 

To treat a concrete slab, you will come 2-3 inches off the wall and drill holes 10-12 inches apart using an 18in-24in drill bit. Using a 5 gallon bucket, mix 4 gallons of mixed solution (.8 fl oz of Termidor SC per gallon of water) and pour the 4 gallons of mixed solution in the drilled holes for 10 linear feet. Usually each hole will take approx 1/2 gallon of solution. It is easier to use a funnel to pour the solution into the holes. If there is a crawl space at any point, dig a 6x6 inch deep trench around any post or cinder blocks in the crawlspace and pour the Termidor SC mixture into that soil.

We recommend storing insecticide cocentrates such as Termidor SC out of direct sunlight and in temperatures no less than 45 degrees nd no higher than 85 degrees. 

Yes, you should drill a hole 2" from the foundation wall (1/2" in diameter/18" deep) every 10-12" apart. You will be dispursing the same amount of finished soultion in the drilled holes as you will the trench around the structure. Termidor SC will be mixed at 3.2 oz per 4 gallons of water per 10 lineal feet (in trench or drilled holes). Please let us know if you need anything else.

We would recommend to keep Termidor applications at least 10 feet from the garden. If the application has time to dry before rainfall or watering to avoid immediate runoff, then this application should be safe.

Termidor can only be used in the attic of a home if it is being used to spot treat an active infestation within galleries in wood or within an inaccesible void that the pests are in. Otherwise Termidor is an outdoor use only product.

We are pleased to hear that the advice and products recommended to you were effective for your treatment. Termidor SC can be applied once (every six months) topically on the exterior perimeter of the house for treating carpenter ants. Please let us know if you need anything else.

ermidor SC is not allowed to be used anywhere other than around the foundation of the home 1-2 feet up and 1-2 feet out. It cannot be broadcast across yards or flowerbeds for any type of insect control, especially with sandy soils. If you want an insecticide that can be broadcast across the yard for ant and general insect control we would recommend something like Talstar P. Its a great general and broad use insecticide that you mix at the rate of 1oz per gallon of water.

Termidor can be sprayed on the home and on the siding where wasp activity has been noticed. Termidor does not give a fast knockdown but it does transfer back to the nest to eliminate the other wasps inside the nest. You should see complete results within 1-3 weeks depedning on the size of the wasp colony when using Termidor.

If concrete such as a carport slab or sidewalk is against the foundation in the area where you need to treat, you will be required to drill through the concrete to apply the termiticide solution to the soil. Using the hammer drill with a 1/2" x 18" concrete drill bit, drill holes every 12" into the concrete along the foundation wall.

You are not only drilling through just the concrete here, but also as deep as you can into the dirt. The deeper the better. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. If you drilled the holes 12 inches apart, then you would have 10 holes over 10 feet that you are trying to fill with 4 gallons. This works out to be a little less than half a gallon per hole. To fill these I would recommend using the one gallon sprayer on a "pin stream" setting so you can force the liquid down the hole and not splash it everywhere. You can also use a funnel and pour the termiticide down the holes. It is difficult to get 4 gallons per 10 feet in the holes, so it is important that you use a long drill bit, at least 18" long so you can bore out enough dirt to hold the termiticide. Sometimes the ground is slow to soak up the termiticide you place in the holes. You may need to fill the holes, then go work on something else for an hour, come back and fill them again, go work on something else... 3 to 4 times to get the proper amount down the holes. Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at a home improvement or hardware store or you can use our Trebor plugs that will close the hole with no concrete mess.

Termites do not usually infest any living piece of wood or tree as they go after dead and decaying wood matter. Are you sure they are termites or that part of the tree isnt dead? Termidor cannot be used away from the foundation of the home/structure unless you are direct treating a carton nest as defined by the Termidor product label. It is not allowed to be used as a trench treatment or drench on or around a tree out on the property for control of any pest. A better option would be to use a product like Talstar P around the base of the tree if you are concerned there could be termites in that vacinity. Talstar would safe to use on the tree and would eliminate any insects in the soil where you treated and any that pass through the soil as well. 

Yes! You can use Advance Bait stations and Termidor combined. The stations will help monitor and the Termidor will be a barrier. Both products will work together not against each other. Please see our article Sentricon vs Termidor for more information about these two types of treatments.

Termidor SC is the # 1 choice for ant control around the outside of your home. Termidor is a non-repellent insecticide that also has a transfer effect. That means that ants cannot tell that the Termidor is there and will walk right over it and then pick the product up on their bodies and inadvertently carry it back to the colony, then through normal social interaction the ants spread the Termidor and wipe out the colony. Termidor only needs to be applied two times per year and is effective for a wide variety of insects including ants, centipedes, roaches, spiders, silverfish, wasps and many other nuisance insects.

Termidor SC should only be applied to the exterior (1ft up and 1 ft out) directly up against the structure only. You will mix 0.8 fl oz per gallon of water and apply once every 6 months. For more information on treating ants, please check out our treatment article.

For the accurate recommendation to apply Termidor in a trench for termites, we recommend to measure the linear feet around the structure. 1 bottle Termidor will treat 60 linear feet of trenching.
