Termidor SC Termiticide/Insecticide - Questions & Answers

Termidor is labeled for OUTDOOR use only.  It can only be used indoors to spot treat termite or insect activity inside wall voids.  It cannot be used indoors for pest control other than inside wall voids.

We would reommend drilling through the gap or 3 inches away from the foundation of your home. Holes should be spaced 12 inches apart and drill holes should be a minimum of 6 inches deep below the cooncrete. Concrete is typically 3-4 inches in depth, therefore, you wold need to drill a total of 10-12 inches.

The trench around the home should be 6" deep by 6" wide right up against the foundation of the home when applying Termidor SC.

Termidor has low solubility in water. It will bind with the soil and should not leak into your living space. 

We do not ship outside of the United States. We apologize for any inconvenience!

Do you know the exact species? There are no known resistance species of ant to Termidor so it would work to kill any ant colony. However, Termidor can not be used in any indoor space unless you are doing a direct spot treatment in a regularly unaccessible area on the whole colony. If you see an area they are trailing you could try either Termidor Foam to use in the galleries you think they are hiding in as this form of termidor has a broader label in where it can be used; or you can try the Complete Ant Kit and use a bait that they would take back to feed to the colony. You will want to check around your home for where the ants could have come in to either seal off these areas or cut back any bushes and trees that touch the home and use a general barrier spray regularly to keep them away in the future. Talstar would be a great easy to use and safe option for a barrier spray.

The only time that Termidor needs to be applied to a minimum depth of 4 ft is if the footer is more than 4 feet below grade. If you read further into the label you will see that a trench does not need to be wider that 6 inches and usually no deeper than 6 inches to acheive the needed barrier.

No, Termidor SC cannot be sprayed on top of any type of powder/dust. If you are no longer seeing activity inside, there is no need to continue baiting. More than likely, they have taken the bait to the colony and eliminated it. You can spray Termidor SC around the perimeter of your home outdoors only. This should only be sprayed twice a year. It is likely that they have been eliminated from your lawn/home if you are no longer seeing them.

Termidor SC has a 3-5 year shelf life from the date of purchase if stored away from extreme temperatures. Termidor Foam should have a shelf life of about 1-2 years. The nozzle and hose should just be rinsed with water after use. Termidor DRY shelf life if stored in a cool dry area is up to 3 years.

If this is the only area, then Termidor would be a great choice.  Termidor does not penetrate through wood, so you cannot just apply it on the wood.  The trick is you have to drill holes into the center of the wood and inject it so it touches the termites.  As long as it only touches a few termites it will work.  You will only use a small amount of the Termidor, which is a concentrate, but the product will last for 5 years on the shelf and is also the best product for treating ants around your home as well.
