Aintree & Melling Labour Action Team is urging Sefton Council to take swift action to deal with a grotspot before the problem worsens.
Molyneux Ward Labour Councillors Tony Carr and Marion Atkinson reported that rubbish had been flytipped on land off Spencers Lane in Melling.
The grot spot was flagged up to the two Labour councillors during their weekly surgery at Aintree Youth Centre.
Cllr Carr, who lives in Melling, said it was important that grot spots were reported to the council and dealt with as promptly as possible because "rubbish attracts rubbish".
Cllr Carr said: "As soon as the resident raised the issue with us, both Cllr Atkinson and myself made a site visit to see for ourselves the extent of the problem.
"The rubbish had obviously been illegally dumped at the site and it needed to be dealt with.
"What you very often find is that if there is a delay in removing flytipped rubbish, more rubbish is dumped and the problem multiplies.
"So we are working with Sefton's cleansing department to make sure the rubbish is dealt with sooner rather than later."
Cllr Atkinson said there was a delay in Sefton dealing with the flytipped rubbish because the council department had been subject to Tory-Lib Dem government cuts.
Cllr Atksinon said: "Sefton Council's cleansing department would normally have dealt with reports of grotspots of this type almost immediately, but the department has been affected by the cuts to local authority funding which have been imposed by the Conservative-Liberal Democrat government.
"These cuts are having a serious impact on frontline services within Sefton like cleansing which are crucial to keeping our communities in the borough tidy.
"But we will continue to work with the cleansing department to ensure that this site is cleared and any other problem sites within the East Sefton area are promptly dealt with."
