hey 9 piont, welcome to the club.(consider your self addicted from this piont forward.).
About your problem. are they freindly enough you could talk them into petting range? If so you could tie them up and call thew animal control.(obviously be careful not to get bit.).
I remember when i was really young my dad had an arrow with solid rubber blunt tip on it he would shoot at strays. It seemed to work when ever they saw him they would take off tail tucked.
when you see them wondering around see if you can follow,to see if they belong to a neighbor. I hope you find a solution soon. for the saftey sake of you fam.
