There are calls for a Sydney council to extend a trial deterring cockatoos from opening wheelie bins as the raids leave streets littered with rubbish.
Campbelltown City Council is testing the effectiveness of residential bin latches over the course of a year to prevent the problem caused by birds and strong winds.
The program will be rolled out over five suburbs in the area due to the limited number of latches however some residents believe their suburb should have been included in the trial.
Ambarvale resident Hana Haddad said the birds are an issue in the area and her suburb would benefit from the trial.
"If anyone drives up and down my area on bin days and night before you'll see the mess the birds make," she said.
Haddad said she has since taken matters into her own hands in order to deter the birds.

"We have recently discovered that if we attach water bottles using zip ties to the bin lids it makes it much heavier for birds to actually lift up," she said.
Residents have also asked the council to extend the trial to Bradbury due to similar issues.
Campbelltown City Council has been contacted for comment.
