I suspect not moths. The moth has evolved for its larvae to live on the protein in animal hair. Think about a dead sheep... there are tiny creatures that decompose and recycle all the flesh - and the wool. If nature had not come up with something to get rid of all those sheep fleeces (and other fur and feathers) then we would be wading around, waist deep in millenias of undecomposed wool and hair. So moths have their place in nature. I can't think why they would suddenly start eating cotton as it is chemically unrelated to fur, wool and feathers, not even made of protein.
Have any of you got all electric cars? Pros and cons please.
