A Merthyr couple say they're been subjected to months of harassment from someone dumping large piles of horse manure and urine soaked straw outside their house.
Jonny and Tyler Walker, who live in Pontsticill, say that the problem started about a month after they moved into the property on Evans Row in late 2019.
The bodies of dead rats have also been left to rot on their front steps and abusive texts sent to family members.
And it's taken a huge mental toll on the pair, with 26-year old nurse Tyler even contemplating taking her own life as a result.
"We moved here a year ago, although the house has been in my family for about a century," said Jonny, a 30-year-old farmer.
"And, for a few weeks, it was great, until all this started happening.
"Suddenly, we'd come out to find all this stinking straw piled up at the front of the house, so we had a word with the person responsible and it stopped - for a while."
But then more waste ended up being dumped against their road level kitchen window, causing foul-smelling slurry to seep down the lane and through their gate.
"They also like to tip the stuff next to where we park our cars at night, so much so we can hardly get into our vehicles the following morning.
"The smell is atrocious too, as you can imagine from all that ammonia, We've got a two-year-old son and I don't want him getting ill as a result of all this.
"Plus, in addition to the dead rats which turn up, it's attracting a load of live ones too."
However, he says that because no actual criminal damage has been done, the police have deemed it a civil matter.
Similarly, Jonny claims that because much of the dumping is taking place on unregistered land, neither does it fall under the jurisdiction of Merthyr Tydfil County Borough Council's environmental services department.
"On top of everything else that's happened this year, it's a lot to cope with, " said Jonny. "In fact, the mental strain has been huge.
"Tyler's had to take weeks off work as a result and has even contemplated ending things a few times - that's how bad it's been.
"And I've lost four stone through all the worry.
"It just seems like no one wants to listen or help us."
A statement from South Wales police said that they were aware of an ongoing dispute between two parties, having received phone calls from both sides regarding the matter.
"Local officers are in the process of working with them to resolve the situation," it added.
"They have also notified the local authority about environmental concerns which have been raised."
