Simply pouring a termiticide such as Dominion 2L around the foundation will not provide ample protection from termites. There is no guarantee how deep the product will absorb into the ground, and you need a termiticide at least 6 inches deep for termite protection. Another option would be to create holes using a rod or dowel that is at least 6-12 inches deep every 12 - 18 inches, then you would still be appling 4 gallons of solution per 10 feet by pouring the product evenly into each hole.
Otherwise, bait stations such as the Advance Termite Bait Stations are placed 2-4 feet out from the structure, outside the dripline of the roof.
You can do the soil drench treatment by digging a 6x6 inch trench around the foundation and pour 2.4 fl oz of Dominion 2L into 4 gallons of water per 10 feet. With the sides of the house with the slope make sure you are doing a backfill method. With the backfill method you want to treat the soil that was removed when digging the trench before placing it back into the trench. If you need any more information about our performing a soil drench treatment you can look on our Termite Treatment guide
If you know where the termites are active we do recommend directly treating that area with Dominion 2L. You should trench and treat around the exterior walls, inside crawl spaces, and trench and treat around each pier for best results. Any part of the home that touches the soil should be treated around.
If you cannot trench with Dominion 2L Termiticide Concentrate in an area you would just have to leave that area open as a possible entry or you can use stations in the area as part of prevention. Applying Dominion as you would a soil drench to a plant would not have the same effect as it would in an actual 6 x 6 trench. It lasts 5-7 years in the soil so would not be applied once a year for termite prevention.
