Silverfish: The primitive silverfish has remained unchanged for millions of years, making it a "living fossil". They eat almost anything including book glue, paper, photos, sugar, coffee, hair, carpets and dandruff and can live for a year between meals.
Bedbug: Not just the subject of a children's rhyme, the nocturnal bedbug really does bite. Its mouthpiece is used to suck blood from warm-blood animals - including humans. Though they do not transmit disease, their saliva can cause itchy swellings on the skin.
Flour mite: A pest in flour mills and grain stores, these mites sometimes find their way into homes where they live in flour, grains or cheese and need humid conditions to survive. A single female lays 500 eggs or more - sometimes as many as 25 a day. Infected food and dry food close by should be destroyed.
