I just got my 500 crickets from gimminy cricket (on amazon) and there where two spiders in the box . I'm not sure if there are more because im afraid to look ( they were pretty big).
Its really not an issue to use the crickets that have not been killed or eaten by the spiders already. Its not like the spiders are going to infest the entire colony like ants can do in no time. From time to time I will find a tiny spider in one of my cricket bins that caught a cricket or two and I simply just remove the spider and the rest of the colony is fine. Ants on the other hand have wrecked an entire cricket bin as nearly all crickets were dead from the millions of ants that had infested the bin overnight. That was before I found a way to keep the ants out.

i read it and its brilliant. if i ever have a problem, i will use that method for sure. i built my own cricket keeper out of a lockable plastic box (cut out part of the lid, hot glued screen, etc), but i then placed that one in a huge lockable plastic box with no vent holes or anything. so far its worked. i open it up twice a day so i figure they should have enough air
