I can't find the crickets in my tarantula's cage...?

I also can't see any shells from him eating them (he had two in there). I got him two days ago and up until last night his crickets were visible. I have to stop at the pet store anyways today to get a temperature gauge because the one i have doesn't work and I was wondering if I should pick up two more crickets just in case?
