I live in MN, so maybe products differ state to state based on insects or whatever. I buy mine at Lowe's. I did last year, and I got it again this year. I sat down and looked at all the fine print, and it's safe for my boys! They looked at me all weird when I picked it up today, because it's still snowing off and on here. Like "Why would you want this?" I explain, "I want it for my snakes, and I want it while it'e still frozen to prevent bugs". They laughed and provided a handsome young man to bring it to my car. Bonus!
