I had a similar flashback to when I was a kid. Me, my brother and 2 cousins jumping from the top of the stairs onto a beanbag in the hallway - Christ knows how we didn’t kill ourselves and why didn’t our parents stop us??

Anyway beanbag burst, polystyrene balls all up the walls and ceiling and I can remember my mum hoovering the walls and ceiling every day for about a week to get rid of them all

 

Those were the days! Did similar with 2 brothers I was mates with. At their farmhouse the bedroom on 2nd floor had a balcony, we put several mattress below and did stunt jumps all afternoon. Remember the Dad coming round at one point with a sheet to put under them muttering about keep the bed clean then just left us to it

The daughter's house where the previous owner filled between the joists with broken up polystyrene and polystyrene beads.

A shallow roof and a 2nd low placed purloin make access to the eves rather difficult.

I figure "hoovering" to be the only practical method, but need a BIG bag or collector.

Thoughts please.

I bought a dual bag chip extractor off of ebay for £300, each bag is 220l. Couple that with a 10-20m hose and you'd have the job done in a day. Someone in the loft with the hose. Someone at the bottom changing out bags.
