My.students are always completely baffled when we go afield in Oklahoma, Mississippi or New York State that I am head to toe covered in long sleeves and using olive drab Vietnam era leg and wrist ties the jingle warfare ones originally designed to keep ticks and leeches out of your greens. Then coated in 100% DEET and 40% DEET on all exposed skin.
Yup alpha-gal my mother in law was this from an unknown source and it’s miserable for her. Having seen it first hand my field methods are not even close to over kill. Every other student except for the vegans who say good all DEET up and wear long cloths even in 100 degree heat. PFG gear for the win there.
Rumor has it ostrich is safe for people with alpha-gal and I’ve had it and you would not know it was not beef.
We also use Sawyers permethrin spray.
