This a worldwide problem that causes damage to carpets, fabrics and soft furnishings. Unfortunately most residual and aerosol insecticides which are sold for use in household situations are rarely effective or appropriate for use on infested objects. My advise is avoid this problem in the first place. There are preventative measures.
The common clothes moth, Tineola bisselliella, have a hunger for fine fabrics like woollen carpets, sofas, cushions and curtains. Anything made from natural fibres is at risk, but contrary to belief, it’s the larvae that eat their way through your home and not the adult moth. If you see damage to your carpets, that resemble bald patches, and see moths in your home, then you probably have an infestation.
The varied carpet beetle (Anthrenus verbasci), like the clothes moth, loves wool. Again it’s the larvae that do the damage. The carpet beetle has overtaken the clothes moth, for infestations, in the UK. Major damage to carpets is widespread and can cost thousands of pounds. New houses are a risk, just like older properties, if you have wool or wool mix carpets.
Prevention of Carpet Insect Infestation
The best weapon against clothes moth and carpet beetle is your vacuum cleaner. Vacuum, vacuum, vacuum! Pay particular attention to edges and under furniture – also vacuum the furniture if made of natural fibres. Regular vacuuming will guard against the problem in the first place. A clean home is not the place for these insects. Regular carpet cleaning 12-18 months will not only extend the life of your carpets but will also guard against infestations.
Keep clean clothes, made from natural fibres, either in vacuumed bags or plastic containers with tight fitting lids. Use moth repellent products in conjunction with this.
I Have a Moth or Beetle Infestation
Skip most of the natural remedies and myths, skip the home use products – call either a pest controller or a carpet cleaner who is licensed to use insecticides. Do not try and use professional products without training and protective clothing & breathing apparatus. Your best line of attack is professional insecticides. If you cut corners then don’t be angry that your carpets, furnishings and clothes are damaged – the financial loss can be incredibly high!
