Yikes, definitely hot wash/dry clean/tumble dry everything cloth if you can as they make a meal out of your natural fibre clothes. It’s not a bad idea to bag the clean stuff until they’re gone.

If you ever get desperate there is Frontline spray which contains fipronil and is cat safe. The downside is a tiny spritz bottle is so expensive. It also kills bees so there’s probably some precautions to take.
