I'm trying to calculate how much Tremidor chemical (concentrate) I
need to buy inorder to properly treat my home myself. Since I didn't
purchase the chemical yet, I can't read it's instructions which might
answer this post.

My home is in southeast Texas. For this chemical, do I just dig a
trench around the house and pour the diluted chemical into the trench?
And what size trench do I need? Is the amount of chemical needed
based on just the volume of the trench or am I forgetting something?
Any recommended web site to buy the stuff?
