Neighbour climbs over the fence next to my house to get home.

Wait, so you’ve failed to draw in the fact that the space between your parking space and the neighbours parking space is, in fact, a road? So people are just walking down the road to the end of the cul de sac and hopping the fence onto a lawn you don’t even own?

yeah, you’re being too sensitive.

I think it may look to others that no one actually own this.
Get your deeds and fence of your land

Your English is great OP, I was just unsure, because the advice might be different if you weren't in the UK x

Are they doing it in the dark? If so, put a plastic crate full of water at the bottom of the fence on your side, wet feet might make them rethink climbing again, or some large rocks, a sprained or broken ankle would definitely stop them, make it look like a rockery then it isn't deliberate.

Yes this .
A few years ago my FIL had his shed broken in to, the intruder got in to the garden over the fence.
The policeman who attended advised him to plant pyracanthas along the fence, he said it was the best deterrent

im end house open plan front garden had kids on scooters etc going over my front lawn, look at band q metal fence with posts just bank in look nice i have had people stop and admire them and ask where i got them from, problem solved,

What about a trellis? Could that soften the look?

Pyracantus all the way. It is quite cheap to buy, hardy, low maintenance, and is fast growing. Lots of berries in the winter, red, yellow , or orange depending on the type. It is quite spikey but not dangerously so.

Are you in the UK OP? I'm wondering due to your spelling. 'Neighbor' is the US spelling, so you might be different bylaws/rules there if that is the case.

Wait I think I get it- the fence isn't your fence per se- it's the boundary for the cul de sac. So the fence goes across the end of the cul de sac from your house to the opposite neighbour. And instead of walking the route cars take, your neighbours opt to walk to the end of the cul de sac and hop the fence, and if they're heading the left they cut through your garden on a diagonal and hop the fence at the most left point instead of going to the middle and turning 90 degrees left.

I'm tired....can someone draw a better diagram? I don't understand who is climbing over the fence and walking over OP's property. Neighbour? Neighbours? Other people? Where are they coming from and going to?

Anyway a 'this is private property, please don't climb over the fence" stuck to the fence should do it.

Spikes plants definitely but also a sign noting that this is private property

if you don't own the lawn and your ownership of the fence stops at the end of your parking space, then they aren't going on your property if they jump between directly into the road between the parked cars. so let people cross at that point and restrict them only on your own property.

can you mark the boundaries of the land you own on the picture?

Motion detector water sprinkler

I had a problem with my neighbour's idiot sons climbing over my back gate to retrieve the neighbour's grandchildren's footballs. (My objection was the damage that they did climbing over.)

I solved it by cutting out wooden 3D triangles (not pyramids) and screwing them to the top of the wooden gate, close enough to make it impossible to get their feet in between, but far enough apart that they couldn't attempt to balance on them.

I'd also considered those plastic spiky strips you get as cat deterrents - I think Amazon sells them. You might try that?

If it's mostly school kids jumping the fence, I would drop the school a polite email explaining that some students keep jumping the fence on to your private property and could they possibly remind the students that they can't use private property as a cut through. Then put up deterents like the spikey shrubs suggested above.

We had this when I was a kid and I remember my mum telling a man off as he was halfway over the fence 🤣

My parents planted some kind of spiky plant and some kind of small hedges.
Over time they grew and last time I drove past that house years ago, it’s a hedge.

Get down to the garden centre!

Can I please second the ha-ha?

Trellis on top of fence with notice on otherside saying private property

It's too late now, but this type of thing needs to be observed before you buy a property. It means effort in visiting it at different times of the day to get a good idea of what goes on in the area.

And yes if you say anything, you won't be liked. I would grow a decent shrub/hedge like others have mentioned.

I was going to suggest barbed wire but perhaps the plants are a better idea.

Trying to think of more solutions… I wonder if you could put ‘private property’ or ‘no fence jumpers’ signage on the walkway side of the fence?

Or as it’s a new development, could you speak to the builder and see if there is anything they can do to help deter people?

You need to nip this in the bud now or others may join the bandwagon. Or you may just have to be ready to spring out your door and have a word with anyone who has hopped over.

I am so annoyed on your behalf 🤣🤣
