A guy around here had mites and he used provent a mite and then called me up and said his sbake was corkscrewing and acting very neuro. I asked him did you spray the snake? He assured me he did not and that he let what he sprayed in the tub dry. Now i wasnt there to see what he did but i went over and saw the snake. What i saw was a beautiful lucy having the worst neuro fit i have ever seen. 4 hours later it was dead. You have to be careful with that stuff
