A desperate Fulham family has appealed to Waitrose for help over an alleyway behind their house which is plagued by flytippers and drunks.
Dawes Road resident Daniel Pitt, 38, said the problems have been going on for five years.
"We get alcoholics, drunks and people using the alleyway as a public toilet," said the dad, who lives with his 16-year-old son Miles and partner Rebecca Bradnam.
He added that people both urinate and defecate on the path and that the family feels unsafe.
"I have had trolleys and shopping baskets thrown into my garden, my back gate was kicked off its hinges recently and the padlock to the shed has had to be replaced three or four times," he said.
Mr Pitt once found a syringe in the shed and says his family is unable to enjoy their garden.He wants his fence to be raised to help improve security.
"I would understand if it was a commercial area, but it's residential," he added."We see people mistreating the area and we can't do anything about it. We are worried that someone might jump over into our garden. I just want it made safe."
He has written several times to Waitrose, which has a store in North End Road backing onto the alleyway, to ask for their help.
Waitrose Fulham department manager, Richard Walton said: "We take this matter seriously and have often had contractors to come in and clean up the area - most recently last week when three visits were made.
"Unfortunately we are not permitted to secure the site at night, as it is a public access route.
"However, we are speaking to the council via police community support officers about regular, scheduled visits to help prevent fly-tipping."
He added that the company has asked its neighbouring retailers to secure their bins at night.
"We would encourage the local community to report anyone misusing the area," he said.
