Termidor SC is not labeled for root aphids. If you can let us know where you will be treating, we can recommend an alternative for you.
Termidor SC is only labeled to be used outside for ant control and cannot be used inside in any way for crazy ants. Products must be applied as directed on the product label. You would need to check with your local regulations regarding what an unlicensed person can legally apply to a public building in your area.
We reached out to the manufacturer BASF for an official answer on this verbiage on the Termidor SC label. Here is what they stated.
“Not using termiticides in voids with Rigid foam insulation” is EPA required language that dates back to times when soil termiticides contained organic solvents/adjuvants which helped them remain in solution long enough to be applied but also damaged rigid foam insulation (think DDT, Heptachlor, Chlordane, or Dursban times; e.g. Pre-Termidor products from the 1950’s through 1990’s). In 1996, the EPA mandated that the language be on all liquid termiticide labels moving forward (regardless of whether the product contained solvents or emulsifiers or not). Termidor products do not contain any caustic emulsifiers or solvents that would damage/ “eat up” the rigid foam board (as the 80WG, SC, HE lines are all water soluble).”
This also applies to the generic equivalent on the market under the branding Taurus SC. If you are needing to foam into the foundation void area where there is foam rigid board, they recommend using the Termidor Foam Aerosol as this labeling does not have that verbiage and restriction on it for use.
The manufacturer of Termidor SC recommends that you use the diluted solution within 24 hours. The longer the product sits in a solution the less effective it will become. Also, leaving chemicals or even just plain water in a hand pump sprayer can cause the seals and gaskets to breakdown. This will eventually require you to purchase a repair kit for the sprayer or even a whole new sprayer much faster than someone that had properly maintained their sprayer.
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.
Termidor is not labeled for use on turf. It is only labeled for use around your homes foundation for termites, ants, and other selected pests. It is important to read and follow the Termidor SC product label? which states that you can only treat one foot up from and one foot out from where the ground meets the structure. The animals need to be out of the area while the product is being applied and they should not come back into the area until it is dry. Since Termidor is a non-repellent product you would not want to apply anything repellant as it will null that affect. For flea and tick control outside you can use the Outdoor Flea Kit.
