Someone told him to try ammonia but he says it doesn't seem to do any
good.

The first thing is to be sure there is no food around for them. So
check for dog or cat food near by. It is possible he has a neighbor
that is feeding them.

My neighbor used to use a trap ( large hav-a-hart ) and then release
them several miles away. Some came back anyway, and other coons moved
into the neighborhood. I think you need to take them at least 10
miles away to be reasonably sure they will not return. He borrowed
the trap from some county office. Maybe animal control.
