Let’s Talk About Fleas
authored by Dr. Becky Marks
How do fleas affect
my pet’s
health?
1.
The biggest problem that fleas cause is skin
allergies. As fleas bite they inject saliva into your pet’s skin. Many pets are allergic to this and develop
itchy skin. Pets will bite themselves,
scratch, rub and roll. Often this leads
to hair loss and raw sores called “hot spots.”
2.
Fleas carry tapeworm larvae. When
your pets gnaw at themselves in
response to fleas biting, some fleas are swallowed.
The tapeworm larvae then develop into adult worms in your pet’s
intestines.
3.
In severe cases, fleas ingest so much of
your pet’s blood that anemia results. This can be life
threatening.
What do fleas do
for a
living?
The key to flea
control is
understanding the flea life cycle.
Fleas are insects and therefore go through several developmental
stages:
egg, larva, pupa and adult.
Adult fleas bite your pet for nourishment (blood). As they take a blood meal they leave their
eggs and feces behind on the pet. Fleas
lay 3,000 eggs in a lifetime. Flea
eggs fall off the pet as they travel in your house or yard. Eggs hatch in 7-10 days in warm and humid
weather. In poor conditions the eggs
can survive up to 2 years. Next they
hatch into larvae. The larvae
feed on debris in the house or yard.
Instinctively they seek cool, dark places such as under
furniture,
baseboards, in closets and bark dust.
Larvae molt into the pupal stage which spins a cocoon. The cocoon lies around in the house or yard
until the adult fleas are ready to emerge.
This happens within a week in optimal conditions but up to a
year until
the conditions are right. The new fleas
(immatures) are HUNGRY. They will take
a blood meal from any source--humans, squirrels, rodents but as they
mature
seek dogs and cats. Fleas can live
several months without a meal (the abandonned beach cabin). Fleas travel 1 mph. They
can cross a yard in no time and they
can climb steps to enter any part of your home.
Important points
to
remember
1.
The
climate in Western Oregon is perfect for fleas. Under
warm and humid conditions adult fleas can lay eggs which
will mature in 3 weeks.
2.
Fleas
are very good at what they do for a living.
They easily survive. Like
roaches they will be here after a nuclear holocaust.
3. For every
one flea you find there are 3000 eggs in
the
environment.
How can I control fleas in my situation?
If you find
more than 5 fleas on your pet you must
treat the pet and the environment.
Two simple steps: 1.
Treat the pet
2. Treat the house
1. Treat
the pet.
A
Bathe the pet to remove fleas, eggs
and flea feces. After bathing you must wait 48
hours
before applying a topical
product. If you can’t bathe then use a
flea comb.
B
Apply Skin applicator- Small packets of insecticide
applied between the shoulder blade.
These
products kill adult fleas for 1 month.
Timberland Animal Clinic recommends
Frontline Top spot Plus. It does not
wash off and
is the best for severely allergic dogs.
Others include Revolution
and Advantage( you cannot
shampoo if you use these).
Frontline
Spray is the same
product and is even faster acting . The
same bottle can be
used on
all size pets. The disadvantage is the alcohol base odor but it quickly
evaporates.
2. Treat the house.
1. Thoroughly clean
your home by vacuuming (then throw away the bag), washing bedding and
don’t
forget the garage.
2. Apply the flea treatment. Hand held sprays work best. Hold the can
knee at height. Cover fish tanks or plants.
All other life should leave for 2 hours. Apply
the spray to every corner, underneath couch cushions, down
hallways and baseboards.
Knockout spray is
the product we do carry because it kills all stages
of the flea life cycle. Keep in
mind that when trying to get fleas under
control, 95% of the flea populations are in the environment
not on your pet. You cannot ignore
this part of the process.
Treat
the yard?
Usually
you don’t have to treat the yard. Your
veterinarian can help you with
this. Bark dust is a breeding ground for these
critters. Remove it if you can.
1.
Yard insecticides. Available in
a hose spray form. They are strong
insecticides and in the peak of the season will be needed if you have
severe
infestation.
2. Nematodes are parasites that
feed on flea
larvae. They also eat aphids.
These are “good” bugs ad environmentally
kind. Must be released early in the
season to be effective. Gardening
retailers carry this product.
Products that are
not safe
for your pet include Flea collars and flea powders. Pets are
treated for
the insecticide poisoning that occurs with using these items. A flea
shampoo
will only leave a 24 hour insecticide residue to protect your pet. You cannot control fleas by a bath only.
