Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet.

You can also use a funnel and pour the termiticide down the holes.

Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at Home Depot or you can use our Trebor plugs that will close the hole with no concrete mess.
