Termidor SC is labeled for all types of termites. How you use it is determined by the species of termites you are dealing with. If you have termites in your home, we recommend doing the liquid treatment as outlined in the "How To Do A Termite Treatment" article and then inside the home where you know you have the termites you will treat them directly by injecting the Termidor into the wall or cutting a hole into the wall and spraying on the wood or however you can get the product to the termites. It only needs to touch a few termites to work.
If your crawlspace is sealed then no you would not be able to dig a trench and apply Termidor inside the crawlspace, you would only apply it around the outside perimeter of your home.
The trenching application of Termidor SC is for protecting your home from termites. If you’re no longer finding evidence of termites invading your home, then the Termidor was successful. Termites travel in all directions under the surface of the soil. There can be multiple colonies in your yard alone. There is no termiticide that can be used in your garden. You can use Termite Bait Stations around your garden perimeter to help treat termites in that area.
No, Termidor SC cannot be used in any type of irrigation application because of backflow issues. Be sure to read the full product label and only apply the product as instructed.
Termidor SC is not labeled for fleas and it is also not labeled for use in a lawn so it is not what we recommend for outdoor flea control. Suspend SC is labeled for fleas and for indoor use, but it is not the best choice for indoor flea control because you can not broadcast spray it over carpeted areas. We recommend you use our Outdoor/Indoor Flea Kit to get rid of fleas in and around your home. Please take a few moments to review our article on How to Get Rid of Fleas for a successful eradication program.
Termidor SC is labeled for use on ticks, but it does have a very limited area that it can be used. You can use Termidor SC outdoors only, immediately adjacent or directly on your home. It cannot be used as a broadcast in the yard for tick control. We would recommend our Outdoor Flea and Tick Kit.
Termidor SC is not labeled for midges and cannot be broadcast on the lawn. Onslaught would be a better option.
Termidor SC is sprayed twice a year for general pest control at 0.8 fl oz per gallon of water, sprayed 1 to 2 feet up the foundation and out on the ground.
Termidor SC is our most popular termiticide for treating and prevention of subterranean termites. Please take a few moments to review our treatment article on How to Get Rid of Subterranean Termites for more information on a successful application.
You can use Termidor SC for the listed pests twice a year at a rate of 0.8 oz (0.06% finished solution) per gallon of water or up to 4 times a year at a rate of 0.4 oz (0.03% finished solution) per gallon of water, sprayed 1 to 2 feet up the foundation and out on the ground.
Termidor SC starts to work within a few days of termites contacting a treated area but if you suspect an active infestation you will need to search and locate exactly where in the home they are infesting and spot treat the gallery directly. Otherwise there is no real way to know if the Termidor in a trench is working. Trenching is only part of protection and treatment for subterranean termites but if you are dealing with drywood, it would not have any effect on the termites since they would never have gone through the treated soil.
Rodding under the slab of a house from the exterior is a complex and detailed process that we do not recommend attempting yourself. We recommend that you contact a local reputable termite company for an inspection and estimate for something like this. If you have termites in the home, then you can spot treat where there are active termites using a ready-to-use termiticide foam such as Termidor Foam which will transfer throughout the rest of that termite colony.
