Blundellsands Labour Action Team has been working with residents and Sefton Council to clear piles of rubbish in a quiet Crosby street.
Residents of Worthing Street and Sussex Street complained to the Labour Action Team that rubbish was piling up behind the houses.
The problem had gotten so bad that some residents said they couldn't open their kitchen windows because of the putrid smell and infestation of flies which were gathering around the bags.
One even told how a rat ran into the house.
Blundellsands Labour Action Team member Veronica Bennett and Crosby MP Bill Esterson immediately raised the issue with Sefton Council.
Veronica said: "The residents were clearly very upset because of this problem. We have had some hot weather recently which has added to the problem, due to the smell and insect infestation.
"When Bill Esterson and I visited the site, there was a large number of bags which had clearly been there a long time. The smell was pretty disgusting and there was clearly a public health issue. There was clear evidence that rodents had been in amongst the bags.
"As soon a we flagged the problem up to Sefton Council, they sprung to action and cleared around 15-20 bags."
Blundellsands Labour Action Team is now working with residents and Sefton Council to ensure that mountains of rubbish is not allowed to build up again.
Veronica said: "We were told that another mountain of rubbish formed shortly after the original mound was cleared.
"So we clearly need to get to the root of the problem.
"As well as ensuring that the site is regularly visited by bin clearance squads as part of the regular schedule, potential fly-tippers need to be made aware of the damage they are doing and how they can be fined for illegally and irresponsibly dumping rubbish.
"Irresponsible dumping of rubbish is dangerous and can lead to the spread of diseases - particularly for children and older people in the community.
"This is something which is now being assessed and will be acted upon."
Sefton Central Labour MP Bill Esterson who saw for himself the rubbish thanked Sefton Council for taking action.
Bill said: "Veronica and visited the site after receiving complains from residents about the rubbish causing smells and attracting rats and other rodent.
"After seeing the extent of the problem we immediately called Sefton Council and within hours they were at the site and clearing the rubbish away.
"I thank them for their swift action and for their ongoing assistance on this issue."
