The shelf life of Termidor Sc is generally 3-5 years. Please make sure to keep the bottle out of extreme heat to ensure the longest shelf life. Be sure to use any mixed solution within 24 hours of mixing.
Drywood termites are all contained in a piece of wood. They do not go back to the ground like subterranean termites. So if you did a trench with Termidor it will not treat the Dry wood termites. Please see our Drywood Termite Control Page.
Termidor SC can be used to treat carpenter ants in trees or nonstructural wood per the supplemental label here. Please be sure to follow the instructions as listed.
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.
Termidor SC if sprayed around structure perimeters for ants and other insects can be reapplied every 6 months. If applied in a trench for Termites, it will bind with the soil and last up to 10 years.
Termidor applied in a trench really helps to prevent pest that are traveling through the soil. It sounds like you will need to re trench since over 10 years and then spray around the foundation 1 foot up and out with Termidor. You may also want to use apply dust like Delta Dust into wall voids for the spiders and other pest.
We would not suggest that Termidor SC be the product of choice for eradicating German Roaches as it can only be applied to the exterior of the structure only. We do have a Roach Control Rotation A Kit that will be great to treat your home with. Please take a few moments to read our article on How to Get Rid of German Roaches. You will find some really great tips on applying the products for the best control. Please let us know if you need anything else.
You will not want to touch the soil treated with Termidor SC with bare hands. You will also not want to disturb the soil after the area has been trenched and treated.
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.
You do not have to treat all of the hollow block walls, only the bottom 2 where the termites could come through the soil with Termidor SC.
We do not advise using a hose sprayer for application as the label recommends to be applied with a hand pump sprayer.
Termidor SC is not labeled for grubs but we do offer products that are effective. Please take a few moments to review our article on How to Get Rid of Grubs for the best results.
No, Regardless of what treatment you are doing Termidor SC can only be mixed at .8 fl oz. per gallon of water. Termidor SC is a non-repellent, if you mix at a stronger strength than labeled you run the risk of taking away its non-repellent properties. Always mix at .8 oz to a gallon.
Termidor SC can be applied to the soil topically (1 ft up and 1 ft out directly up against the foundation) and in a trench for termite control. There should not be any harm done to any grass sprayed.
If that expansion joint is the only area of activity and Termidor SC was used for the initial treatment, most professionals would just treat that area of localized activity. It is possible the termites there came from a colony deep under the soil surface where they would not have come into contact with the existing liquid barrier. You would treat the expansion joint similarly to how you would treat the foundation, using 4 gallons of solution per 10 linear feet, applying evenly into drilled holes. Instead of placing the holes all on one side, however, you would drill them in a zig-zag pattern along the expansion joint. Please let us know if you have further questions.
Termidor SC is NOT labeled for indoor general pest control. The Termidor SC product label only allows indoor applications to wall voids (behind sheetrock), unfinished attics, unfinished basements, and crawlspaces. Termidor SC could be harmful if used in violation of the product label. We would recommend using Phantom indoors for non repellent ant control.
It is completely up to what you prefer, some people are more infatuated with the name brand product Termidor SC but they are the same product and work in the same manner so it is completely left to what you prefer to go with.
Termidor SC should be applied in a trench and drilled holes to provide a barrier around the structure where the termites can gain access. They travel beneath the soil so this application is necessary for eradication and protection.
According to BASF the only times you cannot treat is if precipitation is currently happening or if the soil is over-saturated with water, frozen, or in conditions where runoff or soil movement from the area or treatment site will occur. It would be great to not have rain after your termite treatment, but certainly not something that is “needed (or a must)” for the product to be efficacious or provide long-term residual activity/structural protection.
Professionals would use a sprayer with a crack and crevice straw or termite injection tip to apply Termidor SC into drywall areas, such as that of the B&G AccuSpray with Termite Injection Tip. Keep in mind that you will only apply Termidor in wall voids where there are active termites. An easier way to spot treat would be with a ready-to-use product that comes with a tube and injection tip such as Termidor Foam. You would drill into the infested wood and apply the product directly into the termite gallery. Please see our Termite Treatment Article for more information.
