The 15 bags were finally taken away yesterday from an area at the bottom of Pen Green Lane, Corby.
They were first reported to Corby Council on July 15 by resident Michael Quarrinton. Local councillor Mark Pengelly also reported the flytipping inc
ident.
He is now calling for a council investigation into why it took so long for the bags to be taken away.
He said: "I am extremely disappointed by the lack of action by the council.
"Although this was low risk asbestos waste, it shouldn't have taken this length of time to remove it. I want a full investigation into the matter."
Corby Council's chief executive Chris Mallender said: "I can only apologise to the residents who reported this problem and to local councillors for the time it has taken to remove this rubbish.
"We inspected it quickly and established there was no risk to the public, but there is no excuse for leaving it standing so long."
The bags were among a mountain of rubbish dumped at the site. At the weekend, a shed and a mattress were left in the area but only the bags have been removed.
Mr Quarrinton, who lives in Whitworth Avenue, Corby, said: "The council really should have removed it promptly.
"The area is used by children who are now on holiday from school. They shouldn't play there, of course, but try telling them that.
"We would like to see bollards strategically positioned to stop vans entering the area and, even better, CCTV."
He said rubbish-laden vans and open-back trucks have been seen going into the area and coming out empty.
He added: "People have been seen carrying household junk there. The neighbourhood wardens should report this, not the residents."
