First some information about fleas and ticks. Fleas and ticks
are ectoparasites, parasites that can either live on or burrow into their hosts’
skin. Parasites live at least part of their life cycle on a host, since the host
provides essential resources such as food (blood, sweat, tears), a warm,
protected environment and transportation and transmission to another host.
Fleas are small, wingless, blood feeding insects that have four life stages:egg,
larva, pupa and adult. They can cause allergic reactions and disease to their
hosts.
Ticks are an eight legged, blood feeding ectoparasite that are
closely related to spiders, scorpions, and mites and live on mammals and birds.
They are relatively large compared to fleas with soft rounded bodies. Most ticks
attach to their host and feed for as long as 12 to 24 hours before they fall
off. Most ticks spend about 10% of their lifetime attached to a host. Their
bites can cause local reactions including skin damage, irritation, inflammation
and hypersensitivity. Among the diseases carried by ticks are Lyme Disease,
Canine Ehrlichiosis and Rocky Mountain Spotted Fever.
When it comes to fleas and ticks, prevention is the key. I am
going to discuss various treatments for your pets. If you have an infestation in
your environment, please remember to consult your veterinarian or a professional
exterminator immediately. Flea and tick control is one area of veterinary
medicine that has grown rapidly in the past few years. Some of the most commonly
used products are once a month topicals, sprays/powders, dips, shampoos, collars
and oral medications.
You should contact your veterinarian to discuss which options
will work best for you and your pet based upon their age and health. Products
should not be used on pregnant or nursing animals without first consulting your
veterinarian. I will go into a few of the more popular methods for control. Once
a month topical insecticides are applied to a small area on the back of the pet
and are one of the easiest products to use. Most of these products treat both
fleas and ticks in their various life cycles. Frontline, Advantage/Advantix and
Revolution are among the most commonly used. Not all topicals are created equal.
Please consult your veterinarian before purchasing and applying these products.
Sprays and powders are easy to apply but can be messy. These
also contain pyrethrins and/or permethrin which kills adult fleas and ticks and
in some cases stops flea eggs and larvae from maturing. Dips and rinses
are applied to the entire animal. They kill and repel adult fleas and ticks and
have some residual activity. These substances may contain permethrin, pyrethrin,
carbamates, or organophosphates.
Shampoos help rid the animal of its fleas but most have little
residual activity. When using either a dip or shampoo, it is important to
protect your pets’ eyes and ears.
Collars can be effective but need to be applied properly. The
correct amount of snugness is important for it to be effective. Care must be
taken when animals get wet because the collar can lose it effectiveness.
Oral products, such as Program and Capstar are also available.
Program contains an insect development inhibitor that does not kill adult fleas
but rather sterilizes the fleas. Capstar kills adult fleas but is only effective
for 24 hours or less. Neither one kill ticks.
DO NOT USE PYRETHROIDS, ORGANOPHOPHATES, ORGANOCARBAMATES OR
AMITRAZ WITH CATS.
Remember that with any flea and tick preventative you use on
your pet, the flea or tick must actually be in contact with the active
ingredient for them to die. You may see the flea or tick on your pet after the
treatment but this must happen in order for the parasite to come in contact with
the product and die. Most products kill the fleas and ticks within 24 hours and
therefore reduce the risk of transmitted diseases.
I hope that this helps. Remember that prevention is key.
