I found some info on the net about Fluvalinate.  I was surprised to read
that it is highly toxic to fish.  After reading this I thought about all
the hives that were flooded last year in our area.  One more cause of
declining fish populations.
 
Here are two addresses for info on Fluvalinate:

This info was collected from one of the sites:
 
ECOLOGICAL EFFECTS
 
Effects on Birds
 
     Fluvalinate is slightly toxic to birds.  The acute oral LD50
for fluvalinate in bobwhite quail is > 2,510 mg/kg.  The dietary
LC50 for fluvalinate in mallard ducks and bobwhite quail is >
5,620 ppm (5).
 
Effects on Aquatic Organisms
 
     Fluvalinate is highly toxic to fish (1).  The 96-hour LC50
for fluvalinate in bluegill sunfish is 0.09 ug/l, and in rainbow
trout is 2.9 ug/l.  Its 48-hour LC50 in Daphnia magna, a small
freshwater crustacean, is 74 ug/l, and in mysid shrimp is 2.9
ug/l (5).
 
     Pyrethroid insecticides are extremely toxic to fish with 96-
hour LC50 values generally below 10 ug/l.  Corresponding LD50
values in mammals and birds are in the range of several hundred
to several thousand mg/kg.  Fish sensitivity to the pyrethroids
may be explained by their relatively slow metabolism and
elimination of these compounds.  The half-lives for elimination
of several pyrethroids by trout are all greater than 48 hours,
while elimination half-lives for birds and mammals range from 6
to 12 hours (8).
 
     Generally, the lethality of pyrethroids to fish increases
with increasing octanol/water partition coefficients
