I don’t know about wording on the notices, well I do but it’s been addressed above. Another option is to buy Game Cameras and set them up on property and catch the little buggers. They’re fairly inexpensive, you can get them at Academy, some are battery operated and others can be connected to WiFi. We have battery operated game cameras that store pics on SD cards strapped to telephone poles high enough that a long ladder is needed to access them. You can put them in trees, balconies maybe a light fixture as well. They have a sensor that takes pictures when there is movement (yes, over 2,000) and you should be able to catch them red handed and issue NTV to the parents. Send pics with the NTV. That should put a stop to it. They work well during the day AND at night. NOTE: make sure you set up the date and time because the pics can be time stamped and it makes looking through 2000 pics faster if you have a guesstimate on the time and date of the activity. Also once they are up, plan to review them within 24 hrs to insure they are working properly. If you get the WiFi, you should be able to access the info from your phone. The WiFi are more expensive and you have to be able to get WiFi to the camera location.
