Get rid of moths - how?

Clothes or food cupboard? Different job. Clothes moths: it's the larvae doing the damage, so you have to deal with where they are. Everything out of the wardrobe, wash what you can on a hot wash, and anything that can't be washed goes in a sealed bag in the freezer for a few days. Vacuum the wardrobe, the corners and along the skirting, and empty the vacuum outside. Wool and cashmere go back in sealed bags. Pheromone traps tell you if they're still around. Cedar and lavender only put them off a bit, they won't clear an infestation. Pantry moths: bin anything that's got webbing in it, wipe the shelves down, and keep dry food in airtight containers from now on.
