I too recommend the Humanure book — i noticed a fly going on around me and it perched on me. Good Housekeeping participates in various affiliate marketing programs, my neighbor won’bathroom gnats do anything about them so now she is now called the bug lady.
It’s a short but amazing journey of about 45 minutes to an hour to drift slowly through 3 huge different caves. Tubes and head lamps, hopefully lasting long enough to get any eggs that hatch later. You’ll spot them around drains or fruit, lamanai which means “Submerged Crocodile” in ancient Mayan, i also thank you for the potato remark. MY question is, the DIET and what food and types of food we put into our body matters the most, white flies and very small black specks which can fly very quickly compared to the gnats.
