When Valerie Cappell and her family decided to build their dream home, they determined “to do the right thing” by making it as ecologically-friendly as possible.
But the “Grand Designs-esq” adventure turned into a nightmare when she discovered the highly sustainable wool she had chosen to insulate the four-bed property was hosting a moth infestation of “biblical proportions”.
Despite being reassured that treating the organic substance with pyrethrin would be sufficient to ward off insect invaders, she had to rip apart swathes of the wave-shaped house.
Having consulted experts and sent portions of the infested wool for laboratory analysis, the biologist has now been told by Rentokil that her traumatic experience is shared by many others who opt for organic insulation.
“It was soul-destroying and incredibly stressful when we couldn’t work out where all the moths were coming from,” she told The Telegraph.
“I think our situation could be the tip of an iceberg – many more people must have installed this kind of insulation.”
As with many another new solution to an old problem, say, how shall we organise the economy then? We need to consider a derivative of Chesterton’s Fence. Why didn’t people do it this way before?
