Fleas are very much like us in one way: they like moderate
temperatures. Outside, the cold will kill eggs, larvae and adult
fleas only if the temperature drops below 30 degrees and stays
there for days. Indoors, of course, we keep them comfy year-round.
We have perfect flea-producing conditions inside our homes
throughout even the cool fall/ winter months. The fleas that you
see on your pet, the adult stage, make up only about 1% of the
total population that is in your house. The remaining 99% of the
fleas in the environment are in developing stages.
Because cats and dogs have higher body temperatures than humans,
the fleas generally prefer the animals. When fleas bite people,
the resulting reaction is usually quite itchy and the bite often
becomes infected. Adult fleas are not only a nuisance to humans
and their pets, but can cause medical problems including flea
allergy dermatitis (FAD), tapeworms, secondary skin irritations
and, in extreme cases, anemia. Adult fleas may live from two
months to one year without feeding, so there is often a desperate
need for flea control after a family has returned from a long
vacation. Adult fleas develop inside a pupal cocoon and remain in
a kind of "limbo" until a blood source is near. Waiting hungry
hordes of fleas immediately attack the family returning from
Fleas can reproduce with amazing speed-in one month 10 females can
generate a population of over 267,000 offspring.
Most of the flea eggs, larvae, pupa and adults will be found in
your pet's immediate environment, especially their favorite
resting and sleeping areas.
Flea control is best achieved with a simultaneous, coordinated
effort involving an inspection, home preparation, premise
treatment and pet treatment.
