Weird balls appeared from nowhere

I clean EVERY day wipe work tops down twice a day after cooking so I know my kitchen. Today while wiping down I found around 15 small grey balls behind the utensil holder. What could they be? I called my partner to get them as I was scared they were eggs lol but he said they were more like polystyrene we looked at ceiling and walls no damage. They weren’t near a window so couldn’t have blown in...there was no droppings (mice) as I was worried maybe they were carrying them off somewhere I am baffled?!

Get a bit of cardboard, cover it in sellotape, place it where the balls appear, then you can see if anything crawly is involved.

Do you use a padded lap tray for eating? I kept finding tiny white balls in the kitchen and living room and eventually realised the lap tray had a minuscule hole in the corner of the fabric and they were leaking a few at a time... just enough to really annoy me

Were they like this?

They are insulation from cavity walls.

Partner said they were squishy like foam I couldn’t bear to touch them
