Maybe look at the garden supply store. I have Elector PSP. The active ingredient is Spinosad and it pretty much kills every kind of bug so you have to be careful with it. I have seen similar stuff at the garden store to kill bugs on plants. Look at the labels in the organic insect control area.Thank you and yes it is very frustration I am wondering if I might be able to use a gardening insecticide soap on them. I know I can use it in the coop as long as I let it dry without the birds in there. I just got back from the farm feed store and they have said that the only thing available now with all the new regulations is DE which is very disapointing. The ladie told me that it has become very dificult since they have taken away all the stuff that worked. We are in a hard place here right now if your birds get anything. Grrr.....
