Bot flies can be found anywhere in N. America. In warm states like Florida breeding and infestation is a danger year round. In more northerly areas fall and early winter are the seasons to be especially vigilant for their presence. Many places around the world have bot flies present.
My veterinarian recommended using a systemic flea repellent/killer on Mr. Kitty to protect him from these horrible parasites.
