Video report from ITV News Science Editor Tom Clarke
The National Trust has enlisted thousands of tiny helpers to tackle a moth problem in one of its stately homes.
The creatures have been damaging carpets, clothes, tapestries and other valuable things made from wool or silk. In a bid to solve the problem, the National Trust is set to deploy parasitic wasps at Blickling Hall.
ITV News went along to the stately home to find out more.
