I think you are wrong there saying that toxic chemicals are worse than catching parasites. I have sprayed raid directly on myself several times, soaked in bleach, put 100 percent deet on my whole body and left it on for hours, permethrin concentrate on my skin overnight, and ate the food from the grocery store my whole life, I am still here, and so are the damn parasites. I am trying my hardest to take them out of my body, so now I go after them with a scalpel. Hopefully soon I will get an infection and die, but what doesn't kill you, makes you strongyloider.
