They’re small, brown and hungry - and they’re gobbling our heritage away

They have stood the test of time and rank among our region's greatest treasures.
But now, East Anglia's historic houses and other hallowed sites are at risk from damage caused by an increase in clothes moths and household pests.
English Heritage is today launching a campaign to clamp down on the pest called Operation Clothes Moth, which it says have doubled in number over the past five years, partly due to climate change.
And the charity wants the public to get involved by collecting free 'clothes moth traps' to set up in their homes to help map the spread of insect pests across the country.
Amber Xavier-Rowe, head of collections conservation for English Heritage, said: 'At English Heritage we regularly monitor insect pest activity to ensure our collections get the best possible care, but any sudden change in species behaviour or increase in numbers is a concern.

'Many people around the country will no doubt know the exasperation of finding clothes moth damage in a much-loved jumper or coat, so we want people to come to our sites, collect a free clothes moth trap, and get involved. While we suspect factors including warmer weather and the increased use of heating inside homes is partly to blame, we hope this campaign helps us to better learn how to combat the rise of the clothes moth.'
In 2016, English Heritage conservators counted 2,469 of the common webbing clothes moth, Tineola bissellella, at its sites across the country compared to 1,138 in 2015 and just 800 in 2014.

The moths live indoors and their larvae feed on woollen carpets, clothing, upholstery, fur and even taxidermy, resulting in the appearance of holes or patches.
The charity has been monitoring the spread of clothes moths since 1995, and now monitors at more than 40 sites across the country, with the aim of preventing damage to the more than 500,000 historic artefacts in their care across England.
Monitoring has recently begun to discover another species of moth, Monopis sp., which has previously not been found in historic houses. The traps, which are impregnated with the female sex pheromone of the clothes moth, are available from today.
