Dog flea control and management
requires an integrated approach. For effective treatment both the
host animal and the environment must be treated at the same time.
Control of fleas on the pet generally requires the use of
insecticides. Although flea combs can remove some fleas, combing
should be thought of as a method for detecting fleas rather than
removing them.
If an animal is to be treated for other conditions besides fleas,
such as expression of anal glands, these procedures should be done
before the insecticide application to minimize insecticide contact
with interior mucosal membranes.
A wide range of insecticides are available for flea control. The
pyrethrins and pyrethroids have the lowest mammalian toxicity. These
insecticides come in many formulations including shampoo, dust and
powder, mousse, aerosol and non-aerosol mist or spray, dip, spot-on,
roll-on and collar. Organophosphate drugs for oral use are
available, by prescription from veterinarians.
In addition, some on-animal formulations contain insect growth
regulators (IGRs) that kill flea eggs on the animal. *Remember to
read all insecticide labels, and to follow all precautions and dose
directions.
The insecticides used for flea control vary widely in toxicity and
efficacy. Considerations for selecting a formulation include the
size, weight and age of the animal, as well as the species.
For example, greyhounds are a very chemical-sensitive breed and are
more sensitive to insecticide products than most other dogs. Do not
attach flea collars or flea-killing medallions on these dogs. Do not
use chlorpyrifos, DDVP, methoxychior or malathion on greyhounds.
Cats are more sensitive to organophosphate insecticides than dogs.
In addition, cats groom themselves more than dogs and are more
likely to ingest an insecticide by licking the residue from their
fur.
Kittens and puppies, because of their smaller size, require a lower
dose than adult animals. Young animals may also require treatment
with insecticides of lower toxicity than adult animals. Pregnant or
nursing animals may be sensitive to certain insecticides.
Several products are available for especially sensitive pets and
other situations that require lower risk chemical measures. These
include the citrus peel extracts d-limonene and linalool, sorptive
dusts such as silica aerogel or diatomaceous earth, the insect
growth regulators fenoxycarb or methoprene, and insecticidal soaps.
Theses words may seem foreign to you, but you can always consult a
veterinarian if you have questions. They will have accurate
information on insecticides and their use for flea control on pet
animals. The insecticide label should also contain accurate
information on how a particular formulation of an insecticide should
and should not be used. *Remember to read these labels before
opening the container!
When using insecticides for flea control, remember that the
applicator, namely your pet and you can be exposed to the
insecticides several times. The label may call for the use of gloves
and other protective equipment during application and suggest the
pet not be handled with unprotected hands until the treatment dries.
All personal protective equipment listed on the label must be worn.
As a minimum aspect, chemical-resistant gloves, apron and goggles
should be worn while mixing insecticides and during application to
prevent insecticide contact with the skin.
The working area should be appropriate for containment of the
pesticide and should be resistant to caustic materials. A stainless
steel preparation table and stainless steel or ceramic tub are
ideal. Also, certain parts of the pet’s body (such as the eyes) may
be sensitive to the insecticides and must be shielded during
application. When using flea “bombs” (aerosol cans with a
self-releasing mechanism), follow all the precautions and remove the
pets from the area being treated. For your information, using
excessive aerosols is illegal and may cause fires and even
explosions.
The other important part of an integrated flea management program is
to control larval fleas in the habitat away from the animal. This
can be achieved either mechanically or with insecticides. Mechanical
or physical control of flea larvae involves removal and laundering
of animal bedding and thorough cleaning of areas frequented by the
animal.
Using a vacuum with a beater bar and immediately disposing of the
waste bag effectively eliminates up to half of the larvae and eggs
in carpet. You should also launder animal bedding and thoroughly
clean areas the animal frequents and dispose of the vacuum waste bag
after every cleaning.
Do not put insecticides in the vacuum cleaner bag. This is an
illegal and dangerous use of the products and can harm you, your
family and pets by creating dusts or fumes that could be inhaled.
Another mechanical control measure is carpet shampooing or steam
cleaning. This rids the carpet of blood feces, an important food for
the larvae, and may also remove eggs and larvae. In outdoor areas,
cleaning up the places where animals like to rest reduces eggs and
larvae and removes blood pellets. In yards and kennels, flea larvae
can be found in cracks at wall-floor junctions and in floor
crevices. These areas must be thoroughly cleaned and then maintained
to prevent another infestation.
Recently several ultrasound devices, including collars, have entered
the market claiming to control or repel fleas. Several scientific
studies have investigated these devices and found absolutely no
basis for the manufacture’s claims. Ultrasonic devices do not
control flea populations. It is unnecessary for you to buy these
equipments.
Chemical control of flea larvae can be achieved with insecticides.
Organophosphate, carbamate, pyrethrin, pyrethroid and growth
regulator (hormone mimic) insecticides as well as certain minerals
are available for flea control in the environment These insecticides
are formulated as coarse sprays, foggers and dusts or are
micro-encapsulated.
All but the growth regulators kill flea larvae on contact. Insect
growth regulators prevent flea larvae from developing to the adult
stage. Growth regulators may also inhibit egg hatching. A good flea
larval control program will incorporate sanitation, contact
insecticides and growth regulators for good results.
Flea management requires patience, time and careful planning.
Vacuuming and cleaning areas frequented by dogs and cats should be
routine. The same applies to kennels. If an infestation occurs,
insecticide applications on the animals or in the environment may
have to be repeated according to the label. The need for retreatment
and time intervals between insecticide treatments will vary with the
kind of insecticide and the formulation.
Flea control will not be successful if only one approach is used.
The animal and its environment must be treated simultaneously, and
that treatment must be combined with regular sanitation efforts.
Read all product labels carefully. Do not overexpose your pet by
combining too many treatments at one time, such as a collar, a
shampoo and a dust. Pesticides have a cumulative effect. Be aware of
each product’s toxicity and do not endanger yourself or the animal
by using excessive amounts of any one product or by combining
products.
To end, please remember that flea control will only be successful
when you treat both your pet and the environment simultaneously.
