Which insect likes to eat paper Which insect likes to live anywhere<br />

Primitive and nocturnal, the wingless silverfish is only<br />

20 mm ( 3 ⁄4 in.) long and can often be seen as a silver<br />

flash scurrying across a room. It’s a pest in the house<br />

because it eats paper, books and wallpaper.<br />

Amazingly, the silverfish is more<br />

than 400 million years old,<br />

so was in existence even<br />

before dinosaurs! The silverfish is active at night.<br />

Which beetle feeds on oak<br />

The deathwatch beetle’s alarming name comes from the<br />

legend based on the tapping sound that it makes to<br />

attract a mate. If an ill person was to hear the<br />

deathwatch tapping in the roof timbers, death was said<br />

to be imminent. Nowadays, pesticides<br />

control this beetle in timber-framed<br />

houses, so the threat of the deathwatch<br />

is to the oak trees it likes to munch on.<br />

The deathwatch beetle makes a<br />

tapping sound to attract a mate.<br />

Can head lice jump and fly<br />

No, head lice only crawl. About the size of a<br />

sesame seed, these tiny wingless insects<br />

live only in the hair on human heads.<br />

They hang on tight and puncture the skin<br />

with their mouthparts before sucking<br />

up some blood to eat.<br />

A head louse can only crawl.<br />

Cockroaches can live almost anywhere, but many prefer<br />

warm conditions, so are often found in buildings. They<br />

will eat almost anything, including kitchen waste, so<br />

often become household pests. They have flat bodies, so<br />

are easily able to squeeze into cracks where they can<br />

skulk unnoticed. It is said that a well-fed cockroach<br />

could survive without its head for several weeks,<br />

eventually dying from starvation. This is because<br />

cockroaches don’t have blood pressure<br />

like we do, so won’t bleed to death;<br />

they breathe through tiny holes<br />

found in each body segment; and<br />

they have clumps of nerve tissue<br />

instead of a brain, so can continue<br />

basic functions even<br />

without a head!<br />

How do wasps survive<br />

The distinctive yellow and black common wasp can be<br />

found in both the house and garden. At the end of<br />

summer, you may spy a wasps nest in the loft or under<br />

the eaves of the roof. All summer long, wasps have<br />

been busy making their nest bigger and bigger. Never<br />

touch a wasp’s nest, which may have up to 10,000<br />

wasps inside that will sting if disturbed. Wasps die<br />

naturally at the end of autumn,<br />

when the only wasps left are<br />

young queens. These queens<br />

hibernate throughout the winter,<br />

starting a new nest the<br />

following spring.<br />

prefer the warmth of buildings.<br />
