Re: Bloody hell, nobody told me the police would cut my lawn!
grass is not a breeding ground for mosquitoes - eggs dropped in still water, which is where larvae feed and pupate.
Long grass can be good for wildlife - birds love the grass seeds, lots of bees & other insects visit the "wild" grassland area we maintain.
But I'm not in the "land of the free" - I'm in the UK, and ironically free to make my garden wildlife friendly
