"You shake my clothes and you rattle my rails" okay I'll stop!
I bought these for my Dad as he was telling me he had quite a few moths suddenly appear in the house. I at first thought that my brother had opened his wallet but there were far too few moths for that to have happened.
Upon arrival in their nifty little box there were indeed 24 marble (or olly oop north!) sized Cedarwood balls. The scent is pretty intense in a good way. They smell quite nice! If this drives moths away, all the better. You are advised that if the scent of the balls diminishes you should lightly sand the top layer off (Oof!) using a fine sandpaper or emery board or something to rejuvinate them.
Some moth-y info incase you didn't know. . . .
-The moths themselves are not the problem, rather it is their larvae who eat the fabric when they hatch. The life cycle of a moth is 21 days, so if you shake your clothes outside mothly there's a good chance you'll get rid of them!
-Never put clothes away dirty. Sweat, hair oil and food stains attract moths. This will reduce the chances of moths being attracted to your clothes.
-Moths hate light and being disturbed. Shaking at your clothes once a month or them out in the sun should deter them.
-A hot wash will kill moths. If you cannot wash the item, place it in a plastic bag and put it in the freezer. This will also do the job.
-Mothballs will work better as a deterrent in an air tight environment.
Anyway. . . He's placed them around the house on window ledges and in places where moths lurk. So I will report back in a few weeks with good results hopefully and upgrade my star rating.
Happy moth hunting!
