Good morning all, Some of my colleagues are adamant about freezing collection twice when dealing with pest. They freeze a first time then let everything get back to room temperature for a day or so then freeze again. Is this common practice? I've always thought if we can achieve a reliable -30 that should take care of all adults larvae and eggs? Would someone mind weighing in? Thanks!
