Escaping polystyrene beads -advice!!

[atsgmo]

Over the past few weeks I have noticed constant amounts of polystyrene beads blowing around in our front garden ad patio. They have obviously escaped from somewhere in the brickwork and I wondered if i was a problem and how easy it is to fix or for someone to find the gap. Do I need to be worried about this?

Thanks

atsgmo,
"Do I need to be worried about this" YES its probably cavity wall insulation which should not come out of your cavities.
