Last Summer we moved into a new property - the developers landscaped the area and put down turf. It is only a small road (8 houses - and we do have a management company) but all the gardens are 'infested' with flies (look like common house flies) The children will no longer play in the garden! Is there anything we can spray onto the grass to get rid of them, some one suggested they may well just 'fly' away but will they have laid eggs that will infest us in the summer? Does our maintenance fee to the management company (private road) cover flies??? Any suggestions...please...
