and Bits — March 2010
March
is said to come in like a lion and out like a lamb. Right now,
it’s still feeling a little lion-like as the snow
is falling, but soon the grass will become greener and the leaves
will start budding on the trees. Along with these potentates
of spring, come some less-desirable things such as fleas and
ticks which can cause troubles for you and your pet.
Fleas are tiny little creatures that like
to live on warm-blooded animals. You can see fleas with the naked
eye — they are little brown bugs that rapidly move through the
hair. If you comb them out, they will jump, but they cannot fly.
Adult female fleas suck blood and then will lay their eggs on
the pet. The eggs hatch into larvae which then become pupae,
then adults (remember the butterfly life-cycle? It’s called metamorphosis). They
can actually spend their entire life-cycle on your pet, although
all of the life stages can also end up in the environment — your
house. Fleas can cause a variety of different diseases. Some
dogs and cats are allergic to the flea’s saliva and will
become very itchy from the bites. This is called flea allergic
dermatitis. Usually it manifests along the back, especially by
the tail. For pets with flea allergies, the intense itching can
lead to secondary skin infections. Fleas also can carry Bartonella,
the bacteria that causes “cat scratch fever”. In
addition, fleas can carry tapeworms. The cat or dog licks themselves
and ingests the flea. The tapeworms go into the digestive system
and eventually grow into long worms that feed off the food
your pet eats. You will often see segments excreted in the
stool that look like grains of rice when they dry up.
Controlling fleas involves treating both the
pet and the environment. With the advent of the topical spot-on
flea and tick preventatives, treating pets is much easier than
it used to be with sprays and dips. We carry two types of topicals.
Frontline, which kills the adults, eggs and larvae of fleas and
adult ticks, is safe for dogs and cats. The other product is
called Vectra 3D, which is safe for dogs only. It kills the same
life stages as well as acting as a repellent. The first time
these are applied, it takes about 48 hours to migrate through
the skin and become effective. Both products stay in the skin
and are not washed off with bathing or rain, however, it is best
not to bathe your pet two days before or after application.
We also have a tablet called Capstar that
kills fleas very quickly (within a couple of hours). If there
is a heavy infestation, you can give the Capstar for two days
while the topical is getting distributed to get the problem under
control faster.
You can treat the environment in several ways.
Sprays and/or bombs will kill the adults and eggs in the house.
It is important to follow the directions on the label. Sprays
tend to be more cost-effective because you can address specific
areas where the fleas are most likely to be — carpets, along baseboards
and under furniture and in particular, anywhere your pet
spends a lot of time. If you have a dog or cat bed or blanket,
wash it in hot water. If your pet sleeps with you, wash your
sheets in the hottest water you can and spray the mattress
and box spring. Before you spray carpeting, vacuum thoroughly
and throw away the bag or empty the canister immediately.
Bombs are aerosols that you set off in each room. The problem
with them is that since fleas can’t
fly, you tend to waste a lot of it in the upper areas and it
won’t penetrate deep carpet or go under furniture,
so you may need to spray anyway as well. You can also use
a professional exterminator — make sure they will guarantee
their work so if you have a recurrence, they will come back
to re-treat the area.
If you’d like to learn more about fleas,
come visit our display in the waiting room. Next month, we will
discuss ticks, the problems they cause and ways to prevent them.
