I've just opened a long neglected cupboard.

Under the stairs, full of long abandoned sports equipment and old rucksacks.

I've emptied everything out to have a good clear out and it's full of carpet mite egg cases.

I've sprayed the cupboard and left it for now, but what are the chances I've moved the bugs to the rest of the house by pulling everything out?

Do you have a steam cleaner? If not, plentiful hoovering in the areas you have put the rucksacks etc would be a good idea. I think there’s a risk you might have spread it, yes.

I swear by fumigating with smoke bombs for clothes moths; they might help here.
