A relative discovered they are coeliac a little while ago, which was unfortunate given they were really into their bread making. They gave all their unopened or nearly full bags to me.

Come this morning I discover that not only are they full of flour mites, they've got into my own bags too. 4 full bags gone, plus 5 open bags.

Turns out flour mites aren't interested in gluten free flour or corn flour at least, as those are two of the only things left.

Any tips on how to clean the cupboard so they don't make a return are welcome!
