In article 58,

So now I'm stuck with these invincible fleas. Does anyone know of any
alternative methods I should try? So far I haven't gotten any good ideas,
and the funniest suggestion I've gotten was from a co-worker who suggested
throwing a few dozen cats in the basement as "flea sponges", then carting
the cats out. I'm an animal lover, so I wont take that suggestion seriously
;-) but I am looking for real options...



LOL ...sending animals down there treated with frontline may be an
idea... I would guess you still have a host
animal..rats..mice...opossum...many treatments being aerosols or some of
the formulations of liquid treatments will have no long term effect,
growth regulators included. They will soak into the sand floor/stone.
Dusts would be effective, though I wouldn't use Diatomaceous
earth...works real slow. The pros should have access to Drione which is
silica gel, that also is a desiccant, but contains 1% powdered pyrethrin
which is a quick kill. Any liquid treatments used should be either micro
encapsulated products or wettable powders. You can make a "trap" using
a lamp with a pan of water under neath in the light...set the lamp on
the floor away from where you may be at when you go down there and it
might help reduce the numbers you are seeing.
