Blood
Feeding Pests - are annoying to humans because of their
bite and are also dangerous because they can be vectors of
pathogens, which can cause a disease. These pests feed on
blood from humans and animals. They require a blood meal to
complete their life cycle, egg, larva, nymph and adult. After
a blood meal, they will produce eggs, which will increase
the population inside a structure. Many times animals that
go outside bring these pests inside the home. They will nest
in carpet, furniture, bedding and on animals. The most common
blood feeding pests are:
- Flea
- The flea is dark colored and flattened from side to side
with bristles pointing back. The flea has sucking mouthparts
that are used for the sucking of blood of mammals and birds.
The flea has a complete metamorphosis, which is the egg,
larval, pupal and adult stage. There are many types of fleas
including the cat, dog, human and squirrel flea. Although
the type of flea has a preferred host that does not mean
that they will not attack another type of host. Most fleas
prefer warmth rather than cold and will abandon a host when
it dies. This is also a possibility for the cause of bubonic
plague as the flea left the host and found it's way to a
human for a new host. Fleas are attracted to movement. Often
a deserted house is entered and the vibrations of the movement
that is made causes the fleas to come out of their hiding
places and attack the intruder.
- Tick
- The two common ticks are the brown dog tick and the deer/bear
tick. The brown dog tick gets its name from its appearance,
which is a reddish brown color, and that it is most common
on dogs. This tick rarely attacks a human but they can serve
as a vector for Rocky Mountain spotted fever along with
other disease organisms. The female will drop off the host
dog to lay thousands of eggs in a sheltered spot such as
cracks and crevices up in a wall or ceiling. She dies after
laying the eggs and the eggs hatch within 19 - 60 days.
The brown dog tick does not survive well outside and prefer
a warm dry area. They will attach themselves anywhere on
a dog but adults typically like to attach by the ears and
toes and the larva can be found on the back of the host.
The deer/bear ticks body is a orangish brown and the rest
are dark reddish brown. Precaution must be taken if this
tick is found on a human host because of Lyme disease. The
female will mate with the male during the winter and the
male will die shortly after. The female stays on the host
until springtime where she drops off the host and will deposit
up to 3000 eggs. The deer tick will climb shrubbery or grass
and wait for a passing host. One infestation to note is
the den of animals where the deer tick will feed.
- Mosquito
- Mosquitoes are vectors of numerous diseases such as malaria
and yellow fever. The best way to control the mosquito is
to control its breeding grounds. This includes getting rid
of standing water, making sure not to over water plants
and lawns, cleaning out clogged gutters and making sure
that leach lines are not faulty. The northern house mosquito
is the most common to the northern states. It is a pale
brown with whitish bands across the abdomen. The females
lay their eggs early in the spring. They are laid in masses
of 50 - 400 eggs on a raft like construction.
- Bed
Bug
- Bed bugs are more likely to make an appearance in a house
that is not well kept and clean, but that is not always
the case. Once they are in the home, they will find crack
and crevices to invade. This includes buttons on mattresses,
in the coils of the bedspring, upholstered furniture, behind
pictures and around floorboards. The bed bug is oval in
shape, has a flattened appearance and is reddish-brown or
blood colored when fully fed. The bug inflicts a painless
bite that most people don't notice as opposed to the few
that experience an allergic reaction to the bite. Sensitive
people to the bite could experience nervous and digestive
disorders.
- Fly
- The housefly is not only a nuisance; it is potentially
a carrier of diseases. The housefly is easily recognizable
and common. It is a dull gray with two velvety stripes.
The female is usually larger than the male. The adult female
can lay thousands of eggs in her lifetime. The eggs are
laid in moist materials and hatch in less than a day. The
adult housefly will not live past a month. The fly can only
eat liquids because of he fly's mouthparts but through regurgitation,
the fly is able to liquefy solid foods. The housefly regurgitates
and excretes each time it lands making them a common threat
for up to 100 different kinds of disease causing pathogens;
including: typhoid, dysentery, polio, cholera and others.
The housefly will migrate up to 20 miles but usually stay
within a couple miles of its original habitat.
