What is a good way to keep neighborhood hids off of my cement wall and my yard?

Question

There is a group of kids ages 11-14 that congregate on my sideyard wall. It's a pony wall so they sit there and I wouldn't mind so much if that was all they did but they also run across my rocks/landscaping while playing hide and go seek and they are very loud. As I write this it's 9pm and they are still out there. I've asked them before nicely to please keep off the rocks, that I know they just need somewhere to hang out; as long as they keep it down but they are kids so I don't know what to do. I've thought about buying fake bird p**p to put all over the wall but I can't find any online...please help! I'm in my second trimester and I do a lot of work at home and am sensitive to their noise. At the same time, I"m afraid that if I keep saying things they will destroy property or egg my house...

Answer 1

you should try what i did, kids kept riding bikes through our yard so i got some native cactuses, thorny shrubs, any plant with stinging thorns, and planted them in the yard, if they ran them over it punctured their tires and once they stepped on them barefoot they never came in my yard again, you can get spikey cast iron toppers that you s***w into the top of the wall, they use them to keep birds off building so it might work for kids on walls
