Here are the experts’ top tips for a moth-free home...
Turn off the heat
Turn off radiators as soon as possible and open all the windows regularly to allow air to circulate.
Beware bargains
Our national love of an eBay or charity shop bargain could be contributing to the problem, as old furniture, clothes and upholstery can contain moths, or their larvae — recognisable as inch-long, silvery threads.
Keep all second-hand fabrics in sealed plastic bags until they’ve been thoroughly washed or dry-cleaned.
Shake them off
The moth life cycle is around three weeks, so if you shake out your clothing in the daylight once or twice a month, you’ll disturb them and dislodge their larvae.
Don’t ignore upholstery and furnishings either — rugs and cushions can harbour eggs, so if you suspect a moth invasion, give them a good beating and hang them on the washing line in the sun.
‘Brushing destroys eggs and exposes larvae,’ advises a spokesmen for pest experts Rentokil. ‘Larvae are strongly repelled by light, and will fall from clothing when they cannot find protection.
Deep clean
A powerful vacuum can shift eggs from fibres, but you’ll need to remove the collected dust or hoover bags from the house immediately, or, having hatched inside the machine and merrily feasted on the dust, they’ll simply fly out again.
It’s vital to vacuum regularly under beds, carpets and behind radiators too, to prevent moths settling in. ‘Give your wardrobe and drawers a good clean before unpacking the new season’s clothes, too,’ advises clothing maintenance expert Julia Dee, of the clothing website Total Wardrobe Care.
‘Take everything out and wash, dust and vacuum the area.’
Boil wash
The biggest draw for a hungry moth is stained clothing. Sweat, dried-in food particles and oil from make-up or hair products are like a delicious buffet for moths, so if you’re tempted to skimp on dry cleaning, you’re asking for trouble.
‘It’s vital to clean your clothes thoroughly before storing them,’ warns Julia Dee.
And when you wash items yourself, make sure the water is above 48 degrees centigrade — and the wash programme lasts for at least half an hour — to be certain that every stage of the insect’s life cycle has been killed off.
Seal and store
Once clean, the simplest moth-proof way to store clothes such as coats and suits is in sealed plastic storage bags.
When it comes to caring for very pricey items, such as cashmere and pure silk, ‘wrap your washed cashmere in acid-free tissue or put it in breathable bags’, says Julia Dee.
You can also try freezing garments that can’t be washed. Wrap them in plastic and freeze them for at least 12 hours, to kill off the eggs and larvae.
Mothball to the max
The obvious solution, popular with the Victorians, and still flying off the shelves at homeware store Robert Dyas. Famed for their eye-wateringly unpleasant smell, they contain the moth-repelling chemicals naphthalene or paradichlorobenzene and release other noxious vapours which slowly kill insects.
But unless the area is sealed, the fumes can be too weak to kill sturdy adult moths, and will also make everything you wear smell like an elderly great-aunt. The scent is almost impossible to remove, too, and the balls are poisonous.
‘I wouldn’t recommend them,’ says Dr Randle. ‘They emit toxic particles onto your clothes, so why would you want that next to your skin?’
Go natural
Cedar balls are an increasingly popular natural deterrent. On the downside, although small eggs and larvae will die off, adult moths can become immune to the smell — plus the cedar’s properties fade after a few months.
Instead, try the Moth Box (£6 from totalwardrobecare.co.uk), which stops the breeding cycle by attracting male moths onto an adhesive strip impregnated with female moth pheromones.
