Your flea information is not correct. There are no fleas hopping about the house unless you have rat fleas.
There are over 2000 species of fleas.
Ctenophalides felis (the cat flea that affects cats and dogs and other pets) cannot survive if it falls off the animal! It will die in under 24 hrs. The cat flea eats, has sex and makes eggs, ALL on the cat or dog (and very seldom on humans who are not their preferred diet).
The eggs are slick, and fall off the animal, along with "flea dirt" which is larvae food. These hatch and the little larvae move 18 inches or more, looking for a dark place, like under your chair or bed, and well dug into the carpet, out of the way of the vacuum cleaner, where they pupate. The pupa case is tougher than any known insecticide or chemical, and they wind themselves firmly into carpet fiber so they do not vacuum anyway.
If conditions are right (fairly high humidity from cat breath, and fairy high temperature from animal heat, and increased pressure on the floor from walking, and increased carbon dioxide such as cat breath):
When the flea detects these (nobody knows how), form a cat or dog (or you), and as the animal continues to go by, the flea hatches and leaps onto the animal instantly in one movement before the animal even finishes walking past!!! (It can hang out for six months for such an opportunity).
SO if YOU get a flea, it's because you walked past a pupa - or it walked from cat to you. They do not jump off.
...and then the eat, sex and lay eggs cycle repeats. A cat flea (which is also the main flea on dogs) eats 22 times its own weight in blood per day so this is a serious cause of potentially life threatening anemia, especially in cats who have very little spare blood volume.
Way better to get some Frontline SPRAY (applied by hand not by spraying till the ENTIRE animal is damp, and at least 7 days away from a bath - than to have the anemia - which not only kills but reduces ability to resist illness and infection in general. Fleas are much more serious than an itchy nip, for cats. (Not to mention they carry tapeworm, which can take 6 months to develop in the cat before you notice the problem.)
Some more cat flea information:
* Tho thirds of them are female.
* Ten fleas and their offspring produce 250,000 fleas in month.
* Fleas live 100 to 200 days.
* Fleas thrive at 22C/72F to 35C/95F. Outside that range they die easily.
* They need 50% or more humidity. Lower and they die in hours. (But find a safer drier than DE! Like something edible and nutritious - brewer's yeast maybe.)
* They need shade - sun kills. (So cut the lawn very short if pets go out and treat shade areas)
* Above 5000 ft, most fleas dry out.
* It is dry AND too cool (see temps above), only 5% of pupae survive!
* Ten days of real cold (3C/37F) will kill ALL fleas.
* A few hours of freezing will kill all fleas.
Problem is - the fleas stay warm and moist on the animal.
SO now you can plot your flea warfare, with better information:-)
Good luck, they are very successful pests.
Namaste,
Irene
