I bought some lavender and added dried rose petals to them to make potpourri. Also, I added some orris root powder. Before I knew it, I opened the box to find that moths have eaten my rose petals and looks like they nested up in the lavender. I found 2 white worms. Thought lavender was an insect repellent. I had to throw it all away. Has anyone else had this experience? I live in the south where it is hot and humid, but kept it dry with a dehumidifer.
