Thanks Steve,

As you know, the active ingredient in NIX is the neurotoxin permethrin. While it is in a different chemical class than dichlorvos, this is also a neurotoxin and shows similar symptoms of excess exposure. I have seen cases of dichlorvos toxicity in several pythons and the main symptoms are lethargy, slow response to stimuli, and the flat, lack of muscle tone appearance of the body shape in general. I have never noticed, or heard reported, abnormal movements or star gazing in these pythons. I have seen very little in the literature on this and most of what I know comes from cases I have seen personally. All of the pythons affected were still feeding however, and that probably has to do with the extent of the exposure, although that is just a guess on my part. These snakes seemed to improve somewhat over time and did survive, but still seemed somewhat lethargic.

Unfortunately, I believe you may just need to wait it out and see if it improves over time as I am not aware of any effective treatments available for this condition. If you can locate a really experienced reptile vet, a conversation may provide more information and a possible treatment option. Not sure what to do about the anorexia, but I guess assist feeding may be an option although I am not a big proponent in most cases. However, this case may be an exception and it could help to gain some improvement if she doesn’t begin to feed voluntarily. Sorry I couldn’t be of more help, but definitely let me know how she does.
