I will double check with my vet that they can perform the test.
It is rare to smell the crop dusting in the house, but yes I have smelled it before. However, they have not dusted the crops around me since I got my snake. I got him in the fall of 2020, and they wont crop dust until typically it gets much closer to summer.
I dont think they put flea collars in the display cages, but I wouldnt be that surprised to learn that they had used a flea spray to treat for mites. The more I've learned about reptiles, the less I've liked or trusted all pet stores, but especially mine since it's local.
In his cage I use zoo-med wipe out, and for his water bowl I use a diluted vinegar water mix. In the house proper we dont have any pine/wood cleaners but we do use a lot of lysol for dusting and Bona for mopping. The only place we use bleach is in the bathroom.
I will also call the vet where the ARAV vet used to work. Bare minimum maybe they can perform the test if my vet can't do it?
Thank you all for your replies and support. This is hitting me really hard, especially the fact that even if I perform all the tests, he is probably not going to make it. Whether he was exposed to ambient chemicals, was overheated, got a virus, or he has IBD the end result is still all the same,, right? It was really painful to watch him try to eat tonight. I'm going to try to get him in as fast as I possibly can, but based on the seriousness of his issues I am not very hopeful about his chances.
