Termidor SC Termiticide/Insecticide - Questions & Answers

If you want to pre-treat before the slab is pured to control termites, Termidor SC would be the product of choice. Pre-slab and barrier treatments can last for up to 10 years for subterranean termite control.  For general pest control around the inside of and the outside of the house can be done with Talstar P. It is widely used by pest control companies because it is labeled for almost every insect you could have a problem with and you can use it outside the home as well as inside, it is odorless and very safe for use around children and pets.  It is a liquid concentrate that you mix with water in a one gallon hand pump sprayer.  It will last for 60 to 90 days outside in between treatments.  It is also labeled for lawn and ornamental use, and can be used on trees, plants, bushes and shrubs for all sorts of ornamental pests including Japanese beetles, mosquitoes, and other leaf eating pests.

The best time  to treat for termties is after the winter in the spring. That is because it is easiest to apply a termiticide like Termidor SC when the ground is softer than when the groudn is frozen. Also, peak activity usually starts right as the winter is ending and into the spring. It really depends on your location.

Termite control is an ongoing process. Termites can move into your area at any given time and you should always protect your biggest investment, your home, from these damaging pests.

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.

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.

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 is applied in a 6-inch deep x 6-inch wide trench around the home for the prevention and treatment of termites.  It would not be effective just sprayed on the surface as you would for general pests, because termites are inches below when foraging for food and do not crawl on the surface.  If you have an active infestation of termites inside you will have to find and directly spot-treat the wood they are infesting and apply in a trench. Please review our prevent and treat guides for complete information on how to treat and prevent.

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.
