Moths in the house of quilts

Luckily we discovered them before any/much damage was done. We have cedar balls all over the floor under the bed now, and I am washing things with lavender oil in the rinse. The things that can't be washed in the cold weather have been checked carefully for moth larva and are being stored in lavender soaked pillow cases (not completely soaked!). But oh the panic! I have quilts and afghans by great-aunts and great -grandmothers and textile arts from all over the world. Keep your fingers crossed for me and share any moth-related wisdom...
