These types of issues are very common when purchasing a home. Best Wishes.
One other tip: Trim back trees that may be overhanging or touching your property. Carpenter ants like to use trees and low-hanging branches to get to your home. And, as a general rule, remove any brush, cut wood, etc., that might be up close to your house.
As for your kids, they'll be fine. Even with the regular retreatments.
Hope that helps.
