Gotta agree but include public beatings.
Even parking in the back I can't entice anyone in here.
....stretch some 1/8th inch aircraft cable between a few trees at ankle or shin height (high enough to mow under) and let em get a face plant or two running around the yard. Stretch it tight as ya can and make sure it’s painted flat green or black.
There is also a little PIR sensor water sprinkler called the scarecrow that is for flower beds and gardens to scare off cats etc ...senses heat and sprinkler comes on. Fill it up with an IR dye you can track with a blacklight back to their nest after the punks get marked.

Driveway sensors can cover entire perimeter of property so if the IR beam is broken the owner gets a ping notice he has company. Break out the paintball gun and the ammo for it from the freezer and sting some ass !
Hang a few treble hooks from the trees like christmas ornaments on mono fishing line at head and body height.....
Our new place is gated with security hedge on the outside of the fence that has some wicked thorns, Bougainvillea is our method, nice looking, grows fast, wicked sharp thorns, flowers etc .... That security hedge is an ouch, easy to grow and legal in even kalipornia I am told.....:o)

Whats on the inside of the fence and hedge is something no one will like if they enter uninvited after hours.
There are also some cheap little trip wire blanks that will shoot off the .22 caliber hammer gun blanks if one pulls the trip wire. Very loud yet almost invisible day or night if ya use the green spectra fishing line. No harm , just noise.
PIR Security lights at each corner that wash front and sides and back and sides of homes are easy fixes, fake security cameras, real security cameras. make sure the sensor and lights have a BB/pellet gun proof lens.
Web cameras with free software on your computer.......
A simple clothes pin with 2 thumbtacks as +/- contacts kept apart attached to a loud alarm can be used for a trip wire also. Plant the clothes pin, attach a small piece of plastic to your trip wire and insert it between your contact “thumbtacks” that are wired to the buzzer. Noise, ouch and WTF are something they don’t like.
Till then only put out bait property your willing to have damaged by these assholes.
....just set back an look at your property after dark with all lights out and vehicles garaged and consider the wait a minute delays and noise you can impose on trespassers .
Also when you catch one, prosecute and file a law suit against parents. , ruin the one little POS ya do catch. No more kid gloves on this entitlement generation. Smack em early if their parents won’t. Your doing them and his unknown partners in crime a favor in the long run IMO.
Now add the basic barking pups and 12 gauge to the scenario and ya have a “better” option.
BTW if ya hear or suspect criminal element is on the place simply roll over grab the car keys and hit the panic button on there , even if it’s in the garage or driveway .....they will bail and you can reset in a few minutes. That is if ya have a late model ride with such a feature.
Just what I do , here in poohville.....neighborhood cong has been eradicated thus far.
Good luck Vigilanteman !
