DS (11) had a couple of friends over this morning, and then another came round too, as he heard the others in the garden.
I like DSs friends mostly. They're usually well-mannered kids, and there aren't usually any issues when they're over on a 1-to-1 basis.
But today, with four of them, it was a nightmare. They seemed wild and over-excited, and I felt that I didn't have any control over them.
They were charging in and out of the house, chasing around the garden, and then leaving all the doors (3 separate french window doors) open which meant that doors were slamming as the front door was open for DH, who was working in the front garden.
I asked them to stop, and just use one door, but they ignored this.
We have fairly new borders in the back garden, with lots of newish plants from about April. I asked them to keep off the borders to protect the plants. When I looked out later, a whole load of plants had been broken/ trampled
.
Everyone takes shoes off in our house, especially if you go upstairs (where there are carpets). But today they didn't and I ended up cleaning up mud and leaves from the stairs, landing and boys' bedrooms.
When I told them it was time to leave (I was dropping two of them home) they just ignored me, and it took me several minutes, quite some shouting, and me physically collecting their stuff from around the house and thrusting it into their hands and herding them into the car ( I needed to get back by a certain time and couldn't wait any longer).
I felt quite anxious that they seemed to be beyond my control
, wouldn't listen to my requests, and basically ignored me until I began to lose it with them
.
I haven't had this with DSs friends before, and given that they're now getting to the point where they're almost the same height as me, I actually felt a bit scared/ uncertain about the situation.
I'm normally a fairly assertive person, so I was taken aback by the fact that what's worked in the past DIDN'T on this occasion 
What would you have done? How do you handle this kind of slightly out of control behaviour?
