Since it was installed next door we are loonsig fish in our pond, we have noticed that we no longer see frogs in our yard. I would like some info to encourage the neighbors not to use since this is a twice a day misting action it becomes a chronic exposure condition.pyrethrins, piperonyl butoxide technical and octyl bicycloheptene dicarboximide Have looked on internet but was hoping to find literature pertaining to chronic exposure, suposingly occassionally isn't bad but I'm fighting twice daily chronic exposure.It is the pyrethin based system that sprays 4 times a day. All the info I can find says bad for folks with asthma (my husband) and wxtremely toxic to aquatic life. I was hoping to find someone that has gone up against a company like this and had some ammo to offer. I have already spoke with the Nat'l Institute Pesticide Control and they confirmed my fears but they are an impartial counsel and no real help there.
