The best way to plug an entry point is to match the product with what was originally there. That way you dont have caulk in your mortar and foam in your caulk.

In order to fill a gap properly, you want to go with a 3 step process. First, fill the void with a backing material. You can use spray foam to fill the hole. But dont just use that. Rodents can chew through spray foam. Just use it as a filler or backing material. Then enmesh an exclusion material into the foam. Use a stainless steel fabric, or copper mesh. Finally seal over this with a quality sealant. Sealants are different from caulk. Caulk is not rodent proof. It also cracks and peels off over time. Sealants bond to surfaces, giving you a mouse-proof repair.

Worst-case scenario, evidence of mice can cause problems when its time to sell the place. The best is to stop mice from even entering.

There are certainly some stopgap measures to prevent mice from getting into the house. But the most effective option is to seal the home tightly with an application like spray foam insulation. And while the spray foam product is definitely preventive, it wont be very effective if the mice have already inhabited a space.
