Hi Gang, My "instant" method for insects in seeds is to use mothballs. I put them in plastic container overnight with the mothballs and that seems to do the trick. However, if I have large amounts of wild-collected seed (e.g., from a bucket of prickly pear fruits), I will give them a mist of cyfluthrin. Cyfluthrin is one of the semi-synthetic pyrerthum derivatives (or maybe entirely synthetic). Cyfluthrin is essentially nontoxic for mammals, but like any pesticide (or even any household cleaner), I like to understand what I'm using. So, I've provide a link below for the toxicity information. I just mist the seeds with the sprayer that comes with the bottle for use in the kitchen for roaches and ants (Bayer, I think). Then, I make sure the seeds dry well before storage. Mostly, if my seeds seem clean and pest-free, I don't use any pesticide. I simply dry them down as much as I can (if they are from a species that allows drying). Then, I put them over Drierite and refrigerate them. Sometimes I freeze them. I don't know if it is the extreme dryness, or the cool temperatures, but I have never had insect problems with seeds stored thusly. For seeds that do not dry down and which don't tolerate long storage, I inspect them and if I can't plant them quickly I will give them a shot of cyfluthrin, or put them overnight in mothballs. Cordially, Conroe Joe NOTE: No matter how toxic or nontoxic you think a pesticide is, never inhale it and never let children or pets get into it. Always wash your hands afterwards. In other words, be as least as careful as you would with Windex, or other spray cleaners.
