This is because you are in Perma Guard's Zone 5. It covers CT, DC, DE, MA, MD, ME, NH, NY, PA & VT. The problem is with NY. If you look on Perma Guard's price list, it states (at the top of the page for Zone 5) "** New Yorkers please note. Due to EPA restrictions, we can only ship you Fossil Shell Flour. We have no EPA authorization to ship pesticides to New York." So I believe that because of this New York restriction, no pesticides are shipped within Zone 5.
At any rate, the "flour" is just what you need anyway, should you be feeding it to your animals. It states on the "flour" page that it will reduce odor and moisture in barns and stalls, mixes well with all feeds while guarding against insect damage, prevents worms and keeps virus epidemics from developing, saves albumen, destroys harmful acids, safeguards the stomach, improves health and growth of young animals, causes better digestion, allowing animals to absorb a higher percentage of protein from its regular diet, etc. So if you're looking for worm protection for your chickens and so on, the "flour" does just that. The pesticide is more for treating roaches, silverfish, fleas, flies, etc.
Hope this helps!
