Termidor SC cannot be applied indoors or for flea control. We do carry an Indoor Flea Kit that will be great for this application. You will vacuum daily (discarding the bag or emptying the canister after each use) and spray once every two weeks. It is highly recommended to make a minimum of two applications indoors but may require additional applications depending on the level of fleas.
We actually recommend, if possible, to apply Termidor in a trench inside the crawl space. You will use the same method as you do around the entire structure.
Your treatment should not be done within 24 to 48 hours of any rainfall for the best results. Your trench should be 6'' wide, 6'' deep and 10 linear feet along the structure with the Termidor. You can take a look at our site on How to Do a Termite Treatment to give you the proper application instructions for the best results.
Termidor SC is not labeled to eradicate house flies as it should be applied in the soil for a termite treatment and only on the exterior surface (1ft up and 1 ft out) directly up against the foundation for insects that crawl on top of the soil. For more information on treating house flies, please read the article below. Please let us know if you need anything else.
We recommend that you trench and drill and apply Termidor SC for subterranean termites in the garage and around the structure. If treated properly, it will eradicate colonies within 90 days and bind to the soil and offer 10 years worth of protection. You will want to measure the lineal feet around the structure to determine how much product you will need to purchase for the application. Please take a few moments to review our article and videos on How to Get Rid of Termites prior to treating. For the garage, you will come out 2 inches from the foundation wall and drill a hole every 10-12" apart. You will apply 4 gallons (every 10 lineal feet) of mixed solution into the holes.
