I was going to order some beneficial nematodes and then I read that they should be released twice a season. Would it be good idea to order 2 orders(same shipment), release one now and save the other for release in a month or 2? If so, how long will they last in the fridge?

Also, any specific websites you recommend purchasing from? I was looking at the triple threat from arbico-organics.
