John,
You should always worry about the toxicity
of a chemical to people and pets. However Estar II is almost non-toxic
to mammals. If you look at the MSDS for it you will find these
toxicity rates.
ACUTE TOXICITY
Oral: LD50 (rat): 1,649 mg/kg
Dermal: LD50 (rabbit): >2,000 mg/kg (highest dose level tested)
Dermal: LD50 (rabbit): >2,000 mg/kg (highest dose level tested)
Inhalation: LC50 (rat): >4.6 mg/I (4
hr.) (highest dose level tested)
Other insecticides Pyrethrin, LD50 200
mg/kg, Malathion, LD50 1375 mg/kg. Orthene, LD50 700
mg/kg.
As you can see you might get sick from
drinking the entire bottle, or doing something else stupid. Enstar II
will cause you very few problems. From my own problems with food
allergies, I know there are probably a few people out there sensitive
to Enstar. Taking normal precautions of gloves, goggles, clothing
covering the body and showering immediately after using will prevent
most problems. I follow these precautions as I have developed several
allergies as I have gotten older, and I used to work with much more
toxic chemicals that required them.
From my own experience I am much more
sensitive to Orthene and Malathion than to S-kinoprene.
FYI I got all the LD50 levels by searching
for insecticide ld50. There is a lot of information on the web if you
just look for it.

Since I am approaching my 'sell-by' date I suppose I needn't be too concerned but some more youthful subscribers may wonder, even though Enstar may have "minimal effects on other insects" (Paul Johnson), are there any potential hazards to Homo sapiens, especially when applying it in the confines of a small orchid house in recirculating humid air? Just a thought!
