This is our second summer on Program, and it has certainly performed as
promised. Last summer we had a huge flea infestation in progress when I
began administering Program, and though I began noticing a change in the
flea population within a couple weeks, it took about 6 weeks before the
fleas were really gone (Program doesn't kill the adult fleas--it makes
their eggs unviable, so that new fleas don't hatch or, if they do, the
baby fleas don't survive--consequently you have to wait for all the eggs
laid by the resident fleas to hatch and consume the Program-tainted blood
and lay unviable eggs -- about 4-6 weeks -- in the meantime I sprayed the
house and environs pretty thoroughly as well). But once the fleas were
gone, they were gone. This summer I made sure to begin administering
Program before the flea season, and I haven't seen a single flea so far --
and my cats don't have little scabby scritchy places on their skin, and my
one cat who has a flea-allergy dermititis has a full coat of fur--no bald
patches, no sores, nothing (she's sooooo pretty!). There have been no
other noticeable side effects, though obviously I can't speak to long-term
usage. I certainly hope there won't be any problems discovered down the
line, because for us Program has worked wonderfully! --Sherry
This is the second summer that I have used this product. My opinion is
it works GREAT. Haven't had a flea in the house this summer at all!!
As for side effects............. I don't know, nothing that I have seen
in my two.
