A flea's
lifestyle is very consistent. They live 90% of their life
on your dog or cat and lay eggs. These eggs fall off and
land in your carpet, grass, chair, etc. The eggs can lay
dormant for months or hatch within 2 weeks. The hatchlings
are called larva. These look live tiny black worms. The
larva live for about 10 days and then become pupaes. Pupaes
are live cocoons. These pupaes can last for a few weeks
or a few years. Adult fleas emerge from these pupae and
they live for approximately two weeks. An adult's life
is very short lived but they are prolific breeders. They
can lay thousands of eggs, and the whole cycle continues.
The eggs and pupae are very resistant to any sprays and
this is why treatment sometimes is ineffective. Environmental
treatment is the most important step in flea control so
it must be done correctly. Both the inside and outside
should be sprayed unless the outside has no shade. Fleas
cannot live in sunny, hot, areas. They live in moist and
warm to cool carpets, chairs, bedding; all should be sprayed
on the inside. I stress spraying, as bombing your home
is not effective. The spray should contain an adulticide
and an insect growth regulator. This will slow down or
stop the progression from larva to adult. The spraying
should be repeated in 3 weeks then done every 3 to 4 months.
Always make sure that your pets are out of the area when
spraying and are not allowed back until the spray is dry.
Keeping
the environment clean is important but unfortunately dogs
and cats can go out of your yard and pick up fleas. There
are some excellent products on the market that are safe
and very effective. The first product is Program. The active
ingredient in Program is lufenuron. Program is a once a
month tablet that is given orally. Program doesn't kill
adult fleas but it basically sterilizes them. The way it
works is that the flea bites the animal and takes in the
product. Program is not good for flea allergic animals
and all pets in the household must be on it or it won't
be as effective.
There
are three topically applied products that are very effective
in both killing fleas and keeping fleas from biting. The
first is called Advantage. The active ingredient is imidacloprid.
Advantage is applied on the skin of the back. It doesn't
go into the animal's bloodstream but forms a barrier over
the animal's skin. Fleas don't bite because they feel ill
the minute they jump on the pet. It is very effective on
pets that are flea allergic. It is used every 30 to 40
days.
A second
product is called Frontline which contains the active ingredient
Fipronil. It wokrs very similarly to Advantage but also
controls ticks. When using these products you can only
bathe your pet in mild shampoos like Aloe and Oatmeal based
shampoos.
A third
product that has just come out is called Revolution. This
topical product not only controls fleas but also heartworms,
scabies and ear mites. It also controls intestinal parasites
in cats.
All
three of these products are very safe and the toxicity
level is almost nonexistent. They can be used on very old,
very young, pregnant and even nursing animals. They are
probably the most important products to come out for flea
control in the past 50 years.
There
are a lot of "old time" products that are still out there
but they are obsolete and sometimes dangerous. There is
very little need to dip dogs anymore as the dip is an insecticide.
Flea sprays are almost off the market and the topical products
that can be bought in pet stores (Control, Biospot, Defend)
are all topical insecticides that can cause liver and kidney
damage. These products should be avoided. Flea collars
are not as effective and the best place for these is in
your vacuum bag. Garlic pills, yeast pills, or using Borax
in your carpets and other home remedies are safe but there
are no proven facts that they work.
In
closing, flea control today is much safer and easier than
it was even 10 years ago. As long as there is a definite
plan, there is no reason that anyone should have a flea
problem.
