Flea FAQ

1. Do fleas fly? No. Fleas are wingless, but they are Olympic jumpers.

2. How big are fleas?

Fleas look like copper or blackish pepper flakes, about 1/8 inch long—when you get to see them. Most fleas dash out of sight, heading toward cover. When you do see fleas, you know a dozen of their comrades are in hiding.

Flea eggs, 1/64th of an inch fall off the pet and to the floor, resting in cracks between boards, along moldings, or in leaf litter.

3. Does the cat flea attack dogs?

Yes. Ctenocephalides felis, the cat flea, is the number one external parasite of cats and dogs, and several other family pets: rabbits, guinea pigs and ferrets. So, don’t get confused by the name; it’s called cat flea, but it is the number one flea of all pets, dogs included.

4. Has the cat flea developed resistance to flea products?

Yes. The cat flea is resistant to more products than any other type of flea, but rotating products helps decrease resistance.

5. Does the flea attack wild animals?

Yes. The cat flea plagues wild animals as much as it plagues pets. Wild animals that carry the cat flea, and can deposit flea eggs and larvae in your yard, include raccoons, opossums, deer, cattle, coyotes, foxes, bobcats, skunks, ferrets, and Florida panthers.

6. Do adult fleas jump on and off animals?

No. Once an adult flea has found a pet to feed on, it remains on the pet to feed, mate and lay eggs. The eggs fall of the pet and the larvae and pupa mature off the pet in the carpet and grass.

7. What’s flea dirt?

The female consumes 15 times her body weight in blood, which passes through her digestive system and is defecated out onto the skin. This comma-shaped feces is called flea dirt. The female flea lays her weight in eggs daily, and can lay for over 100 days.

8. How do fleas suck blood?

Fleas drink blood using two mouth parts. One part squirts saliva and partially digested blood into the host, and the other sucks blood from the host. This is how fleas transmit pathogens, like tapeworms, to your pet.

9. Can fleas suck enough blood to kill pets?

Yes. Fleas have taken enough blood to kill kittens, puppies, calves, lambs and goats.

10. How fast to fleas feed?

About 60% of fleas will feed within 5 minutes of jumping onto your pet, and almost 100% of fleas are engorged with blood within 1 hour of being on your pet.

11. How fast to fleas lay eggs?

The female lays eggs 24-36 hours after her first blood meal. Fleas lay up to 50 eggs a day, which is equal to their body weight. They can lay this many eggs because they suck up 15 times their body weight in blood daily. This blood lust can continue for 3 months.

12. How fast do flea eggs hatch?

If the temperature is 95 F and there is 70% humidity, half of all flea eggs hatch within 36 hours. If it is only 55 F, half of all flea eggs will hatch within 6 days.

13. How long can newly hatched fleas can live before they attach on a pet?

In a humid environment, over 60% of newly hatched fleas can live without a host for 2 months. In a cool, dry environment, only 10% will live without an immediate host. Humidity is the key to flea survival.

14. How quickly can a flea go through its entire life cycle: egg, larva, pupa, and adult?

The entire flea life cycle can take place in less than 3 weeks.

15. How long does it take a flea to develop into a million fleas?

6 weeks. In 3 weeks, a flea can pass through its entire life cycle and can lay 1000 eggs. In another 3 weeks, those eggs can hatch and lay 1,000 eggs each, so within 6 weeks, it is possible to have a million new fleas.

16. How do fleas survive the freezing winters?

Fleas, eggs, larvae or pupae die if the temperature falls to 37° F for 10 days. Still, fleas survive up north where it’s much colder than 37° F. Why? These fleas survive on stray domestic animals and wild mammals—raccoons and opossums and in

• barns
• heated garages
• kennel bedding
• carpets
• pick-ups carrying hay bales for traction

18. Do fleas like some areas of the pet more than others?

Yes, fleas prefer the rump and the head where your pet cannot reach to remove them. Fleas also find the belly a choice area to invade. On some cats, you'll find fleas high along the spine between the shoulder blades.

19. Does everyone have a flea problem?

Unfortunately, flea problems are widespread, and few homes are spared; not even the spotless homes.

Veterinarians’ homes are no different. They have flea problems too.

One veterinarian spent 3 months ridding an apartment in Chicago of fleas. In fact, fleas tormented him so much that he became a veterinary dermatologist and devotes himself to making others have an easier time of it with fleas than he had.

In the South, fleas are a year-round problem because they survive during the easy winters. In the North, winter temperatures fall, but fleas survive in heated garages, barns, hay bales, on wildlife, and on pets that stay indoors.

Humidity is probably the single most important factor in flea survival, but in hot, dry areas with low humidity, fleas survive because they can remain cocooned for months. Parts of the world that are exceptionally hot or dry, though, have no resident flea problems at all. Of course, most of us wouldn’t want to live there either.

20. Do fleas transmit diseases?

Yes. The cat flea transmits tapeworms and several infectious diseases, including the plague.

Whenever your pet snaps at a flea and swallows it, it has exposed itself to Dipylidium caninum, a tapeworm that attaches to the small intestine where it sucks up nutrients. In a few weeks, you’ll find dried, tan, rice-like tapeworm segments attached to the pet’s rectum or in the feces. These tapeworm segments carry eggs and can eventually infect humans and other pets. One more reason to prevent fleas.
