Moths can be a serious pest especially in large numbers, when they can be very destructive. Although the adults have a very short lifespan, typically only living for 2 or 3 weeks, the caterpillar stage can last for up to 6 months – and it is these hungry, growing grubs that do the damage. Protecting your clothes, upholstery and fabrics may often involve a mixture of prevention and cure.
The eggs are laid among suitable fibres, subsequently hatching into white-bodied caterpillars with brown heads – and healthy appetites! Fully grown and having eaten their fill, they form a pupa within a silk cocoon from which the adult will eventually emerge. Generally only one generation is produced each year, but where conditions are favourable the moths may breed more frequently.
