I wouldnt say that its not toxic. Its not approved for organic use now. Acute toxicity Rotenone is classified by the World Health Organisation as a moderately hazardous, Class II(18). The LD50 for rats (the amount of the chemical lethal to one-half of experimental animals) is between 132 and 1,500 mg per kilogram(19). One factor in this wide variation may be the differences in the plant extracts used(20). The acute oral toxicity of rotenone is moderate for mammals, but there is a wide variation between species(21). It is less toxic for the mouse and hamster than for the rat; the pig seems to be especially sensitive. Recent studies have shown that in rats, rotenone is more toxic for females than males. It is highly irritating to the skin in rabbits(22), and to the eyes. In rats and dogs exposed to rotenone in dust form, the inhalation fatal dose was uniformly smaller than the oral fatal dose(23). Rotenone is believed to be moderately toxic to humans with an oral lethal dose estimated from 300 to 500 mg/kg(24). A lowest lethal dose of 143 mg/kg has been cited in a child(25). Clinical experience seems to indicate that children, in particular, are rather sensitive to the acute effects of rotenone(26). Human fatalities are rare, perhaps because rotenone is usually sold in low concentrations (one to five per cent formulation), and because its irritating action causes prompt vomiting. If the dust particle size is very small, and can enter deep regions of the lungs, rotenoneÂs toxicity when inhaled may be increased. Acute local effects include conjunctivitis, dermatitis, sore throat, congestion, and vomiting. Inhalation of high doses can cause increased respiration followed by depression and convulsions(27). On the basis of rabbit studies, absorption through the intact skin is low(28).

That looks like a grasshopper nymph... my favorite control for those is just to pluck them off and step on 'em, but insecticidal soap will work just as well ;-)

Well, her description immediately brought the name of the insect to my mind, but I rejected it at first because I wasn't aware that MOLE CRICKETS were found in the northeast. As I told Dee, when she sent me her images, these little guys are the bane of Southern golf courses and lawns. There are several species of mole crickets; what Dee has found is probably the Northern Mole Cricket. Would you look at those incredible digging utensils they have?? You wouldn't believe how powerful they are if you hold them in your cupped hand. Here is a link that might be useful: Mole cricket images galore

Sheila, I wouldn't use a dust indoors no matter how careful. Even with a mask, it will settle on your skin and clothing.It will remain on the surfaces and move each time you move around inside or the wind blows. I would never use it. Not sure what you are trying to kill, but I use an organic pest control and I believe he uses Diatomaceous Earth as a barrier around my lanai and property. It took care of a lot of bugs, I no longer get ants anymore inside the lanai. No roaches or grasshoppers. I'm amazed that in 4 years I have not had any insects (except thrips, aphids and scale) or slugs affect my plants. My major issues are fungal and thrips. As I said, this company states they are organic and come quarterly. No bug problems inside or out. I think dust is dangerous in an enclosed space. Jane
