We have been living in our house for 4 years and I was horrified last summer when we were infested with moths for the first time... They were everywhere! I was killing two or three in every room every single day, and was worried for my curtains, towels, cashmere jumpers... I only bought 2 strips in the first place, cut them and put them all around the house. It did not seem to make a difference, but I then bought an extra pack, and kept the strips whole. One went in a cupboard in the living room, the other in my husband's wardrobe at the other end of the house, and after a week or so, all the moths were gone, and they did not come back!
