My parents live on a housing estate built in the last 10 to 15 years, lived there for about 7 years.
They have a neighbour who has a rat problem. He flatly refuses to do anything about it.
He did some building work on his garden during lockdown1 that disturbed the nests under his sheds and decking. The little bastards used my parents garden as a play area for their young during this but would retreat back to his when he down tools every night.
My parents spent a fortune on pest control services which neighbour never once offered to reimburse or share. Pest control officer confirmed the Nests are definitely in neighbours property. Lots of potion, traps etc and eventually it seemed the issue had been resolved.
Then 2 weeks ago the little fuckers are back, massive holes dug under the fence (owned and erected by neighbour) and into my parents garden. Dad has confronted the neighbour who refuses to see that the issue is because of the frankly disgusting state of their garden....there is rubbish everywhere although doesn't seem to be food waste, building materials everywhere, piles of dirt where he has dug out his garden. He has basically created a rat paradise and my parents are suffering as a result.
I have said to my parents they need to report the guy to environmental health but they are reluctant as despite my dad's less than friendly confrontation with their neighbour he doesn't want it to escalate too far as they still have to live next door.
What can I do? Can I report the idiot neighbour without it coming back on my parents?
Does anyone have any wise ways of getting rid of the vile creatures that doesn't involve a flame thrower or napalm?
