I think they are considered invasive in Canada, so you won't easily find a source for them. I would look into different roaches or perhaps worm or cricket options if possible, since those might be easier to source.
Best I have been able to find is the Probugs Eco-Fresh Dubia - they are freshly preserved and while not suitable as a staple they have been handy to have as a backup. Northern Gecko sell them. There’s also a decent aquatic/reptile store i found downtown Vancouver sells them in single packs (5 roaches) if you want to give them a try.
In your perspective does my baby bearded dragon look healthy or unhealthy? Does she look bloated? she is active and eats very well also she is in her basking spot all day
