Protecting Wool Materials from Damage by Moths

SOME of the modern sprays and insecticides are remarkably efficient, disposing of every trace of moth without affecting the fabric, but even more important are the means, recently perfected, of treating wool so that it repels the moth. Wool so treated retains all its natural softness and comfort, yet moths will not go near it. However, even when all wool is proof against moth, a few simple and regular precautions will always be advisable to ensure permanent immunity.

Grubs do the Damage

Most people know that it is the moth grub and not the moth they see flitting about that does all the damage. Autumn is the danger period, for that is when moths lay the eggs from which the grubs hatch out. The eggs themselves are often very difficult to detect, each being no bigger than a pinhead, and they are usually in the darkest and dustiest places. The secret of moth prevention is to clear away the eggs before they can turn into grubs. Wool likes fresh air and moths do not but like to be left quietly undisturbed in the dark, so hanging clothes out in the sun now and then is a very good idea. Wool thrives on such treatment, for the fresh air revives the fibres. Clothes should be brushed well and shaken gently, and at the same time a careful inspection should be made underneath seams, folds, cuffs, turn-ups, and other likely places for sign of moth eggs. Protecting Upholstery Moths attack upholstery in an underhand manner, more often than not eating their way through from the back. Therefore the important treatment for upholstery is a regular brushing, beating, and pummelling, paying special attention to the undersides of chairs and cushions, the grooves round the seats, and all out-of-the-way places. Curtains, too, should be brushed regularly to prevent moths settling down. As well as preventing moth damage, a little regular treatment such as this keeps wool upholstery and curtains looking their best.

Care of Carpets A carpet provides nice cosy quarters for moths, and the most obvious place in a closely fitting carpet is round the edge where it hugs the wall. Dust and fluff gather there and should be brushed out regularly, particularly in autumn, when the eggs are laid. Another refuge for moths is where the carpet goes under furniture. Storage Precautions Before any woollen material is stored it should be spotlessly clean, as dirt attracts moths. If articles are being put away for any time, a newspaper parcel should be made of them, moth crystals sprinkled inside, and the parcel sealed with gummed paper. As an extra precaution, cupboard shelves may be scrubbed with disinfectant, particular attention being paid to all corners and crevices. The floor of the wardrobe or cupboard should be kept free from dust and fluff and the door shut tightly. Moths are especially fond of fur, so if possible furs should be kept on their own and given special care.
