Discouraging dog poo on our grasd

[lovefairylights]

Our house covenant says we can't enclose our front garden so along the street we all have lawns.
We've had a problem with a late night dog walker who was letting their dog poo on the path last year on the dark winter nights but it seemed to stop after we kept cleaning the path with bleach and jeyes fluid.
It's recently started again and judging by the size of the poos probably the same dog walker but it's being done on the lawn this time. I'm guessing the disinfectants will kill the grass and I can't remember what has been written before to discourage it. (We do need to stop it as DS is 2 and has already stepped in it)
Any ideas?
We share the front with our semi neighbour so don't really want to get rid of the grass for spiky plants as it would look a bit odd and the dog could still run round to our bit and poo as the neighbours would still have lawn.

I've found that a sign saying 'please clean up after your dog' has worked wonders. This is strange, as I don't think dogs can read. It does mean that the lazy slob concerned has to actively disobey an instruction rather than just assuming 'not my problem'.

if that doesn't work, put up a sign that says 'area treated with rat poison, keep animals away'.

if that doesn't work, consider doing it.

A lady down the road from me put up a sign written in permanent marker that said 'CLEAN UP YOUR OWN BLOODY DOG SHIT'. And people did.

The council replaced it with a polite no fouling notice, and it started again.

Sometimes a firm message that is clearly from an individual works best

believe me, I was tempted!!

We actually did something like this but it made things worse - he put the poo in a bag and left it on the boot of the car for a few nights then got bored and went back to poo on the pavement till my mum told me to clean the path with neat jeyes fluid and I guess the dog then chose to no elsewhere.
Any ideas? my other half thinks get some big bags of pepper or mustard powder generously thrown around the grass but I can't see how that will work and not get blown away...

Would it help if you got an outdoor motion sensor light? I don't think they're too expensive. May put the pooper off pooping of light comes on for all to see.

We've got a similar covenant, and a similar problem, so we are about to put wooden troughs across the front of our garden. There are four houses that face onto a path, two on each side, and all of us are doing the same thing.

Hopefully the inconsiderate person will actually take the hint.

It will be the same dog, I've noticed with my own dog that he always poos at the same location on a walk. If its late at night as previously suggested a motion sensor might act as a deterrent. If it was me I'd be looking out the window ready to give them a piece of my mind.
