Idk if anyone had a similar problem before, but I live in EU by the countryside, at first there were only a few but now it happens more and more often to see drones passing over my house, I am sure they are civilian drones because law enforcement has no reason to use them since the area is quiet (and honestly I doubt they would be able to do so), however it bothers me enough to know that there are people who get over the fence and enter my property going to look at what they want, does anyone have any advice on what to do?
The best bet is to let your local aviation authority know. They are generally the ones with the actual powers, as well as the knowledge to apply them.
At least in the UK, the laws cover anything that leaves the ground under an open sky. There are exceptions for RC toys and drones, but they have limits. One of the limits is you cannot fly within a certain distance of anyone or anything not under your control.
Basically, most places require your permission to fly over, or near to your land. If they are overflying, they are breaking the rules.
It’s worth noting, depending on the size of the system, it can be difficult to judge distances. The ones I work with are large. We regularly have officials insisting we are massively out of our flight area. GPS logs show that it was well within the entire time.
