As Termidor SC is labeled roaches outside only. We would advise using Demon WP as a residual spray and to look at our How to Get Rid of German Roaches Guide that provides excellent information on how to treat for german roaches and gives instructions on what products to use and how to apply them.
We would need more information as to how your home is constructed to know where you may think you need to drill on your brick of your home. Normally, horizontal drilling through brick is not needed unless you have a hollow block wall leading into a basement that you need to treat on the inside. You would follow the instructions laid out at the link below to our Termite Treatment Guide on how to do a trench around the foundation of your home with Termidor to get the 10 year protection from subterranean termites. Any areas you have concrete against the foundation (i.e., patio, sidewalk, driveway/garage) where you can't trench, you would need to drill a hole every 12 inches across and treat the soil below the concrete. These instructions are also laid out in the guide and product label of Termidor SC which you can find a link to under the Product Documents section on the Termidor SC page.

Termidor SC should be applied at a rate of 1/2 gallon per hole drilled every 10-12 inches. It is still applied as 4 gallons over 10 lineal feet like with the trench.
If you spray a good barrier around the foundation of the home with Termidor it will technically control any species of ant that would crawl across it. You can treat 1 foot up on the side of the home, and 1 foot out on the ground, as well as around any other entry point for the ants like windows, doors and where pipes or wires enter the home. The ants will walk across the Termidor, pick it up unknowingly, and take it back to the nest to eliminate them at the source. Please see our Fire Ant Treatment Guide for recommendations on how best to treat for this pest.

Bora-Care is usually the preferred choice if most of the wood is exposed and it is raw wood you are treating, meaning it is not painted, stained, or sealed, it is just normal wood. Bora-Care is made only for wood, and you do not have to know exactly where the termites are for it to work which is a plus. Bora-Care is sprayed evenly over all exposed surfaces of the wood and actually penetrates through the entire piece of wood. When the termites in the wood try to consume the wood after it has been treated, they ingest the Bora-Care with the wood and die. No matter where they are in the wood the Bora-Care will find them as long as you treated the exposed wood that you can see. The other main benefit is that Bora-Care stays in the wood forever, so you will not have to worry about termites or beetles infesting the wood that you treated ever again.

Termidor SC has a shelf life of 3-5 years if kept in a cool dry place. The "rotten" smell that is coming from the Termidor Sc could be a sign that it has gone bad. If Termidor was been exposed to extreme heat, this could lessen the shelf life.
