We discovered a mud tube coming from a small gap in our tile grout, right next to the baseboards. It's practically coming out from the floor. Where do we drill to inject the foam?
You want to inject the Premise foam into the studs of the wall by the baseboards. You may also want to perfom a perimeter trenching around the stucture and apply a termiticide like Termidor SC. Please review our article Do It Yourself Termite Control. They may travel behind the wall voids but the main nest will not be behind it. They will most likely be using the studs as a food source and traveling up the sides of the studs. You will not foam the entire void, rather you will drill a hole close to the top of the ceiling/stud on either side of the stud. Once the holes are in place on each side, inject the foam into each hole for 5-10 seconds, allowing the foam to expand but slide down the sides of the studs where they would travel. If you are seeing them along the baseboard areas, drill holes every 8-10 inches apart across the area between studs, about an inch or 2 above the baseboard. Use the same injection rate for each hole and let dry. The foam has some residual for about a month after it dissipates so if any are missed in the initial application the rest of the colony should be affected.
