We've just moved into a house that was previously vacant for about 3 months. This is our first week in and we've noticed that someone else keeps using our bins and putting things in the wrong bin! We've now got a general waste bin full of maggots and I don't know what to do. Do we have to sort through the bin and clear it out? Or do we contact the council and ask them to take this bin away/request a new bin? Lived in a flat prior to this so don't know where to begin.
