Can you show the math for Termidor dilution?

When I do the math, 0.80 fluid ounces of Termidor per one gallon (128 fl. oz.) of water = 0.80/128.8 = 0.006 = 0.6%, not 0.06%. What am I doing wrong?


When diluting Termidor SC with water, you will use 0.8 fluid ounces of the product per 1 gallon of water. There really is no math required for this. You will just measure 0.8 fluid ounces of the product using the measuring reservoir on the bottle. You will then pour that amount of product into 1 gallon of water. When using a 1 gallon sprayer, the idea is to fill the sprayer up half way (1/2 gallon), add the 0.8 ounces of Termidor SC, agitate (or shake up) the chemical, fill the sprayer to 1 gallon, and agitate the chemical again. 

If you are using the product for the trenching method for termites, which requires 4 gallons of finished solution for each trench, then there is a little bit of math required. Since 0.8 fluid ounces goes into 1 gallon of water, you will use 3.2 fluid ounces per 4 gallons of water. 

0.8 x 4 = 3.2

0.8 represents the standard rate of the product.
4 represents the amount of water you are going to dilute the product in.
3.2 represents the total amount of product you will need to use in 4 gallons of water. 

Therefore, you are going to dilute 3.2 fluid ounces of Termidor SC in 4 gallons of water. You will then pour the entire 4 gallons of solution (Termidor SC and water) into ONE 10 foot trench. You will need to do this until 4 gallons of solution has been applied to each trench around the entire perimeter of the home. 

I hope this explanation provides you a bit of clarity. If not, please feel free to give us a call at (866) 581-87378.
