Squaw Smoke Mosquito Repellant, Antigo, WI

I found this bottle at an estate sale in Antigo, Wisconsin about 10 years ago. It is a machine made corker about 5 inches tall with a label reading from the top of the label downward, “Genuine Jean Batiste’s SQUAW SMOKE in liquid form As Effective Safeguard Against the Bite of Mosquitoes and Other Insects, DIRECTIONS Apply to Exposed Parts, SERVALL LABORATORY, Antigo, Wisconsin.
This little bottle with the now politically incorrect brand name on the label seems to date to the 1920-40 decades and is still half-filled with what is presumably the concoction produced by Servall Laboratory. The cork is quite tight and I have not tried to open it for fear of destroying the original seal and unleashing what today might be a potential chemical spill Even if it is not that lethal, I have no interest in applying some and testing it on the mosquitoes the size of sparrows that we get here out in Mukwonago. But here’s the rub of a different sort, I have completely struck out on finding anything on Jean Batiste, Squaw Smoke, or even Servall Laboratory. Presumably Servall was some small, fly by night, or from-home operated business in Antigo.
Does anyone know anything about this company and other products it might have produced?
