Re: fleas:

Here are a few of the great many wonderful past posts from the
highly accessible and easily used FHL Archives to help you and
to help your vet if your vet is not used to treating ferrets:

Hello everyone,
Since it is spring (at least here in the South) and the
beginning of bug season, I thought I would post about the
flea, tick, and heartworm products that are safe for ferrets.
FLEAS: There are several safe and effective flea products.
1) Frontline, Frontline Plus, and Frontline spray are all safe
and effective against fleas. One tube of the cat size per ferret
once a month. With the spray version: 1 spray per pound of
ferret (ie a 2 pound ferret gets 2 sprays) once a month.
Frontline, Frontline Plus, and Frontline spray also kills ticks.
2) Advantage is safe and effective against fleas. One tube of the
small size cat per ferret once a month.
3) Revolution is safe and effective against fleas. One tube of the
cat sized per ferret once a month. Revolution is also called
Stronghold in Europe. Revolution will also kill ticks, ear mites,
prevent heartworms, and deworms each month.
TICKS there are several safe and effective tick products.
1) Frontline, Frontline Plus, and Frontline spray are all safe
for tick control. Again one tube of the cat size once a month.
With the spray: 2 sprays per pound of ferret (ie a 2 pound ferret
gets 4 sprays)
2) Revolution is safe and effective for ticks. Again one tube of the
cat size
per ferret once a month.
3) Advantix is sort of safe for tick control on ferrets. Advantix
contains
2 ingredients: imidacloprid for fleas and permethrin for ticks.
Permethrin
is absorbed thru the skin and into the blood stream. Permethrin at high
doses can cause problems to ferrets (and dogs and especially cats).
Frontline would be a safer option because it does not get absorbed thru
the skin. It stays on the oil layer on the skin.
HEARTWORMS: there are several options for heartworm prevention too.
Yes, ferrets can and do get heartworms, and heartworms are usually
fatal in ferrets.
1) Heartgard for cats, Heartgard Plus for small dogs, and liquid
ivermectin
are all safe for heartworm prevention. One chewable tablet once a month
or liquid ivermectin orally once a month.
2) Interceptor (Milbemycin oxime) for small dogs (2-10 lbs). One tablet
once a month. These tablets are small enough to crush up and mix into
ferretone or baby food. They are beef flavored and some ferrets will eat
them. Interceptor should also deworm them each month and should
control ear mites too.
3) Revolution for cats (5-15 lbs). One tube per ferret once a month.
Revolution will prevent heartworms, kill fleas, ticks, ear mites, and
deworm each month.
4) Advantage Multi is the newest heartworm product. Advantage Multi
contains 2 ingredients: imidacloprid for fleas and moxidectin for
heartworm
prevention. Advantage Multi will also kill ear mites and deworm each
month.
One tube of the kitten size (2-5lbs) once a month is the recommended
dose.
Advantage Multi is called Advantage Advocate in Europe.
Hope that helps clear up the confusion,

is one I had to carry in for the author, Julie Fossa, possibly because
the free host the FHL had in its middle years, Smartgroups, had a
tendency at times to just refuse or lose member posts on its own
when it was under spam attacks (which happened pretty often):

This is carried here with the author's permission:

From: Julie Fossa...

It's not uncommon for flea populations to explode five to six weeks
after warm weather gets here, and so do the posts from owners faced with
evicting the uninvited guests. While there are over 2000 flea species,
the cat flea 'ctenocephalides felix' is the species we encounter on our
pets, including birds. Rodents have their own species, however, from
what I could find, the standard eradication methods would be effective
for either.

Fleas are flat, side to side, with hair-like bristles on their bodies
and legs that aid in locomotion. They have three pairs of legs to
facilitate jumping and have an exoskeleton, eyes, and mouths equipped to
suck blood. They can jump 150 times their body length and 9-15 inches
high. Adult fleas cannot survive or lay eggs without a blood meal. A
female will eat fifteen times her body weight in blood daily. Fleas
can be carriers of tape worms if your pet ingests them. If you see one
flea, there may be 100 more hiding in furniture or bedding.

Fleas and butterflies have the same life cycle. They have four stages:
Eggs, Larvae (caterpillar), Pupae (cocoon), and Adult. Completion of
the life cycle can range from 2 weeks to 8 months with an average of 3-4
weeks. However it can stall as long as two years.

While sources vary on the percentages, flea populations are comprised of
50% eggs, 30% larvae, 15% pupae and 5% of biting adults. Another source
claims 34% eggs, 57% larvae, 8% pupae, and 1% biting adults. It doesn't
really matter which source is right, you can still have a big problem if
you only see one hardworking female adult.

A happy well fed female can lay as many as 15 to 20 eggs in a day.
Another other source claims she can produce more, 31- 46. She can lay
up to 600 during her lifetime. If your pet has just 10 females for one
month, they can multiply to an army of over one quarter of a million
strong in various life stages.

Once the female finds a host, she will take two to three blood meals so
she will have extra droppings to feed the young larvae. Feeding periods
last from four to seven minutes. She will lay her eggs two days after
taking her first blood meal. This pattern will continue for her lifetime
which can be from 12 up to 113 days.

Flea eggs are not sticky, like many parasite eggs, so after they are
loosely laid on the hair shafts, they will drop off where the pet
sleeps,
plays or rests. These eggs will then hatch anywhere from two days to two
weeks, becoming larvae. If the eggs are deposited indoors, the larvae
will reside in cracks and crevices in floors, along baseboards, under
rug edges, in furniture or beds.

If the eggs drop off and hatch outdoors, the larvae will thrive in sand
and gravel, preferring moist sand boxes or under shrubs.

Larvae take anywhere from a week to several months to develop. Their
food consists of digested blood from adult flea feces, dead skin, hair,
and other organic matter. Larvae do not live off of fresh blood from
the animal. The larvae will establish a silky cocoon made of pet hair,
carpet fiber, grass cuttings, dust, or whatever is available, for it's
next stage of development. Once in it's cocoon, the pupae will develop
into the adult flea. Fleas usually survive the winter in the larval or
pupal stage. They grow best during warm, moist, temperate seasons.
Optimal temps for fleas are 70 to 85 degrees Fahrenheit, with 70%
humidity.

Adult fleas can emerge or remain in the cocoon until the environment
is right for their survival. They will emerge at the detection of
vibration -caused by the movement of the host, pressure -such as an
animal laying down on them, or presence of heat, noise or carbon
dioxide -indicating a potential blood source. Adult fleas emerge fully
ready to populate their environment. They can hibernate in the cocoon
from two months to one year without feeding.

Given fleas' ability to multiply and survive, how do you protect your
pet
and home? There are several options, beginning with treating your yard
to prevent you or your pets from bringing in a hitch hiker.

Products known as Insect Growth Regulators (IGR) prevent the completion
of the life cycle. This is applied to your yard and is effective for 30
days. There are some links at the end of this post for sites that offer
these products. Also, local pest control companies usually offer this
service.

There are a number of products available to protect your pet. Using
these products will help keep fleas out of your home. These include
Frontline, Frontline Plus, Advantage and Revolution. The Frontline
products and Advantage work on the surface of the skin and oil layer
and are NOT absorbed into the skin. Revolution and Program are absorbed
into the bloodstream. These products not only eliminate fleas but will
eliminate ear mites and skin mites. Revolution will protect against
heart worm and Program is also used to treat ringworm, a fungal
infection. We will look at them individually.

Advantage: Benefits include stops fleas from biting in 3-5 minutes and
starts killing fleas within the hour. The fleas stop laying eggs, so
no eggs means no larvae, no pupae and so no new fleas. The literature
claims 98-100% of adult fleas are dead within 12 hours. New exposures
die within 2 hours and 99% of the larvae are killed within 20 minutes.
Per the FHL archives, the dose is one whole tube of the 'less than 9
pound' cat dose. It is off-label use for ferrets, but safe and
effective.

Frontline and Frontline Plus: Comes in a spot-on and spray. Dose for
the spot-on is one tube of the 5-15 pound cat dose which will provide
relief for 4-5 weeks. Frontline spray is the most economical choice. It
has no expiration date, and the dose is 1 spray per pound of body
weight.
Frontline kills fleas, eggs and larvae for an entire month. It also
kills ticks. It is waterproof even after swimming or bathing. It is
safe to use on puppies and kittens (and ferrets). The Frontline Plus is
gentle enough to use on pregnant or nursing dogs and cats. Frontline is
not absorbed into the bloodstream and is off-label use for ferrets, but
is safe and effective.

Revolution: This product not only deals with the fleas, but will prevent
heart worm when 1 tube of the '5-15 pound' cat dose is used once a
month.
Lower doses did not protect against heart worm. This is a safe and
effective dose for ferrets. For ear mites, the dose needs to be applied
on the back of the head, between the ears, and needs to be repeated
after
3 weeks. Revolution is absorbed into the bloodstream, which is how it is
able to protect against heart worms. Revolution is safe to use at the
age of 6 weeks. Pfizer actually tested this product for effectiveness
on ferrets.

Program: Available in pill form, Program works when the flea bites your
pet. The flea then lays eggs that cannot hatch. The negative with this
product, in my opinion, is that it doesn't give your pet relief from the
fleas very quickly and it takes longer to break the cycle. However,
Program is safe and effective, and is even an effective treatment for
ringworm. It is considered off-label use.

Advantix: This product is NOT safe for ferrets nor cats. Nix the
AdvanTix!

How do you get rid of the fleas you already have in your home? Vacuum
all carpet, floors and furniture. Put a flea collar in the bag or tank
and destroy the contents after each use. This will remove as many fleas
and eggs as possible but it will also stimulate the fleas in the cocoons
that are ready to hatch to emerge due to the heat and vibration. Vacuum
prior to the treatment then again 24 hours afterward. Treat with a
product that is safe for pets. Your vet should be able to recommend a
good product. There are also links below with products that treat fleas.
One website recommended vacuuming every day for 2-3 weeks to expedite
the
removal of fleas. Remember to empty the bag so they can't jump back out!

You need to wash your ferret's bedding, after treatment, before placing
them back into their cage/area. Don't forget to wash toys and other out
of cage bedding or places fleas might hide.

For hardwood floors, vacuum floors and baseboard then spray floor making
sure to reach all cracks and crevices. Make sure the product you select
for treatment is acceptable for use on hard surface flooring.

Preferred products have Permethrin with an IGR such as Flea Fix. Another
excellent product, Knockout E.S., is available through veterinarians or
by Internet, and has a pyrethrin base. This product kills active flea
infestations and keeps infestations from developing. It prevents flea
re-infestation for 7 months.

Carefully follow all safety precautions for protecting all pets during
any chemical treatments. Pyrethrins are natural insecticides produced
by certain species of the Chrysanthemum plant. Other chemicals are added
in to make the pyrethrins more effective.

All information with exception to personal experiences were taken from
the following websites. There are other pertinent posts on the FHL for
those who are interested. Also, purchasing the larger doses of Frontline
and Advantage and using measured drops for the ferrets is an accepted,
vet approved, means of protecting our ferrets from fleas.
