do mini crickets grow up?

Question

I buy 12 mini crickets for my house gecko (because he needs small ones)... by the time he eats them all its weeks later, and 1 or 2 of the crickets seem large- did the crickets grow or did the pet shop give a few of the wrong crickets. how long does it take the baby crickets to grow into adult?

Answer 1

Crickets do grow pretty quickly! If you buy baby crickets, in a couple of weeks they will more than double in size. A full grown cricket is about an inch long and pretty big.
