I have 2-3 month old walking sticks for rehoming. Mine laid eggs, they hatched, and now they need new homes with more room for them to be awesome. Fun to watch and easy to feed. They eat rosebush leaves and blackberry leaves.
You will need a fine mesh screen for the top of your tank.
$20 for 5 walking stick bugs. $2 a piece for each additional bug. I have a lot of them, lol.
