"This product works in our 200+ year old house!"
We moved to a house that's 200+ years old. It's listed, so cannot fit with sealed double glazing (unless we win the football pools). It had moths. In rooms and attics. Didn't realise the problem for some time. Tried lots of stuff. This product is the one that worked for us. The good thing is that it seems to work in lots of locations ~ free-standing wardrobes, airing cupboards, chests of drawers, and the small 'nooks and crannies' that old houses seem to have. Also, they are easily movable. If put in a place that is moth free, and no new moths are caught, then I simply move them elsewhere!
