Yep, there' s an "oh, no" moment when you realize your pet (and house) have a problem. After that all you want to know is: how do I get rid of them?
You do need to know how to get rid of them, but you
also need to know how to prevent them in the first place.
DOES YOUR PET HAVE FLEAS?

Fleas also cause a distinctive pattern of hair loss over the
base of the tail, back, tailhead and thighs (especially the inside).
WHAT HARM CAN FLEAS DO OTHER THAN ITCHING?
Fleas are more than just itchy pests. They can cause a few
serious issues including:
- Flea allergy dermatitis and flea allergy
- Infection - tapeworms, typhus, tularemia, plague, and bartonellosis (cat-scratch fever)
LET’S GET RID OF AND PREVENT THE FLEAS!
First two points of flea treatment:
1) Treat ALL pets in the household year round with effective
flea control.
2) To eliminate an established infection treat all pets at
once and treat the environment.
What works to clear fleas? In our area we have what we like
to call “super fleas.” They are resistant to many flea control products (e.g.,
many fipronil-containing products like Frontline Plus, Frontline TopSpot, and
their knock-off prodcuts). What works: For an oral preventive Nexgard,
Bravecto, Comfortis, and Program (the flea control in Sentinel). If you want an
effective topical product then use Advantage (imidicloprid), Revolution (selamectin)
or Frontline Gold or Frontline Tritak. The Serresto collars are the only
effective collar.
For the environment, you can certainly hire a pro, which can
be vital in super infestation situations. Otherwise what works well is
vacuuming. Vacuum your entire house (hardwoods, carpets, all flooring) every 2
to 3 days for several weeks.
If your pet has a serious skin infection and fleas, then an
exam with your vet is necessary.
