Tis the Season
- for fleas!
Signs
of Infestation
Fleas are masters of their universe. They can hide in a forest
of pet hairs, especially on long-coated or double-coated dogs
or cats, and can zigzag among and between hair shafts faster than
an Olympic skier
then theres the leap. Now you see
a black speck with legs, and now you dont. So, don't depend
on seeing the flea to know if its there. Instead, look for
clues.
If a dog or
cat scratches, he may have been bitten, but he may also have dry
skin, an allergy, or mange mites. If he bites at his rear end
especially around his tail or the inside or outside of his thighs,
fleas are a possibility. If you find tiny black particles that
turn red when dropped on a damp paper towel, this is flea-feces
evidence.
While dog
or cat may be slightly bothered by a flea or two or may play host
to a dozen or more without serious consequences, they may be the
unlucky recipient of a tapeworm infestation courtesy of mama flea.
A dog or cat may be allergic to flea saliva and develop mild to
severe skin reactions to even a single bite, and the tapeworm
or the skin bumps may be the only signs that the fleas are present.
Flea Treatment
Dog owners have access to an overabundance of flea control products
from herbs and electronics to biological controls. Powerful chemicals
such as Dursban and Diazinon and systemic insecticides such as
the ingredients in Proban, Prospot, and Spotton seem to be on
the way out. The systemic insecticides can build to toxic levels
in your pet if not used extremely carefully. Some products repel
fleas, some kill adult fleas, some kill larva or eggs, and some
prevent fleas from growing and reproducing.
Garlic and
brewers yeast are popular flea repellents with the natural
crowd, but there are no tests that indicate these diet supplements
are effective. However, many pet owners believe they work.
Electronic
flea traps are sometimes used to attract and kill the pests before
they attack the dog, but they do nothing about fleas in the yard
or flea eggs or larvae in the house.
Flea collars
have mixed results depending on the chemical involved, the size
of the dog or cat, and the density of the pets coat.
The new generation
of controls includes natural or genetically engineered pyrethrum,
a daisy; flea-specific growth inhibitors (products containing
fenoxycarb and methoprene); an environmental control that desiccates
fleas and larvae; a once-a-month pill (Program) that prevents
the formation of chitin, the fleas external body covering;
and new surface products applied to the dogs skin or coat
(Advantage and Frontline). Unlike the toxic insecticides in products
such as Spotton, Proban, and Prospot, the ingredients in Frontline
and Advantage are not absorbed into the bloodstream and are toxic
only to fleas, not to dogs, cats or their owners. The type of
control depends on the extent of the pets problem and the
preferences of the pet-owner. The pill or topical application
takes less effort, but they should not be used alone in a heavy
infestation because they do not treat the environ-ment. The pill
works when fleas bite a dog or cat so may not be suitable for
an allergic pet. The topical solutions kill adult fleas and have
some residual action as long as they remain on the pets
hair, even hair that has been shed on carpets and furniture.
Pyrethrum
and permethrin are often found in shampoos and in pet and premise
sprays containing growth inhibitors. With mild flea infestations,
an occasional bath with a permethrin shampoo or a Program prescription
may do the trick, especially when combined with a premise spray
that contains a growth inhibitor or with application of sodium
polyborate, an insecticide that kills fleas by lethal constipation
and desiccation. Infestations that are more serious may call for
the big guns, especially if the pet is allergic, but whatever
combination platter of flea treatments you choose, make sure you
have something on hand for the hot, humid days of summer when
fleas can invade in huge numbers.
Springs is
in the air, so its time for flea treatment everyone, and
kill those nasty ticks while in the process!
