I
am sure you will have heard the saying "Sleep tight and don't
let the bed bugs bite" but mention the bed bug today and
most people will think you are talking about house dust mites,
such has been the relative demise of the one and the ascendancy
of the other both in reality and in the publicity attached to
them. This is quite a remarkable turn about in knowledge and awareness
when one considers that in the late nineteenth century more than
70% of Britains housing stock was infested by bed bugs.
Bed bugs are large enough to see, look particularly under the
mattress and in the seams, in and around the bedframe, and along
any cracks or peeling paint in the wall or picture frames. Check
in the cracks of any wooden furniture. You can also spot bed bugs
droppings, which may be tinged with blood.
They are excellent hitchhikers and
are usually unknowingly transported in or on luggage, clothing,
or other belongings that are carried by people as they travel.
Current outbreaks have been traced to increased domestic and international
travel. This is a particular problem for hotels where turnover
of occupants is always constant. Bed bug Infestations can also
occur inadvertently by bringing bed bug infested furniture, mattresses,
or used clothing to one's household. Bedbugs may also travel between
flats in blocks of flats after being brought into the building
by one of the aforementioned routes. Bedbugs may wander between
adjoining flats through voids in walls and along pipe/cable runs.
Bed bugs are active
mainly at night. During the day they hide in cracks and crevices
in walls, floors, beds and furniture. When only a few bed bugs
are present, they lie close to human sleeping areas; when numerous,
they can be found in many rooms of the house. A characteristic
bed bug odour is frequently present in a home infested
with bed bugs.
Bed bugs are oval,
reddish brown, wingless and are flattened from top to bottom.
Adult bed bugs measure about 4-7mm in length. The female will
lay up to 200 plus eggs in small batches of about half a dozen
a day attaching them to the surface as she moves along. The species
requires a minimum temperature of at least 11degrees C to hatch
successfully. Bed bugs show an incomplete life cycle; that is
when the eggs hatch, a small nymphal form of the bed bug emerges.
Bed bugs grow by moulting several times. Nymphs look very much
like the adults except they are smaller and not sexually mature.
There are five nymphal molts and each nymph must have a blood
meal to be able to moult to the next size. Adults feed once a
week on average, but feed many times
during their four months or longer life span.
Bedbugs are extremely difficult to
eradicate. That is why we recommend three visits.
