 It's 9 a.m. and while the wood lice are having a gasp on the dressing table, the trunk's been gutted from the inside out by this mighty homewrecker. Woodworms lay their legs in cracks and crevices and it can take the larva three years to grow into adults. They gnaw, bite, and tunnel through the wood they call home which can have a devastating effect on your home. Usually all you'll see are the calling cards, the telltale holes, small piles of dust in crumbling furniture. All this activity usually goes on unseen, but in this house, nothing escapes Bug Brother's prime eyes. And there's another slippery customer skulking in the shadows. Even the light-sensitive silverfish can avoid our cameras. It's their diet which makes them a problem. They'll nibble literally anything. They produce cellulases, enzymes which break down cellulose, the normally indigestible marterial in plant tissue. That means they can even get nutrients from paper, so the books aren't safe, neither is the glue holding the books together. Silverfish will even eat larva and the family photos are at risk too. Another interloper, usually more at home outside takes advantage of a free meal. A bee scrambles for a pollen fix, collecting nectary in its honey sacks. It would take the load back to its hive. Unfortunately for this bee, pollen's not the only thing it will carry home.
