Yeah, I haven't taken on the growing my own situation yet fully. I have read on it and I know it takes months until your colony is up and running, and you may incur die-offs if you try the isolate and stress method to get them to pupate.
These last couple weeks I pretty much bought enough to get me by for two weeks so I haven't had any to play with. When I have an excess of funds I will buy many extra for cheap bulk prices and then start a breeding colony on my excess.
As of right now I'm just covering my feeders, although sometimes in my cups of mealworms I find a few pupated worms as well as over a couple weeks a few turn on their own. As of right now I have 1 beetle and 2 ready to turn, 2 died in the process. Very small I know but I'm not really doing it on purpose I'm just attempting to make use of what I have rather than throw it away or leave the pupae for the worms to eat it.
Oh and I dont buy necessarily from a pet store like petco or petsmart etc. Its a local reptile shop that sells in small or bulk quantities much like the online store systems. I was in complete and utter shock when I went into a Big Als Aquarium and a petsmart just to compare the costs as this kid was telling his parents how good the feeder prices were at the aquarium.
basically he was spending $5 for 25 supers, where I could get 50 for 6... or like what I did this run, 100 for 9. No bulk costs just.. buy more cups.. So this kid would have to spend $20 for 100 for what I pay 9... and thats just the tip of the iceberg as the price per worm price ratio goes down as you increase the increments. You can buy 1000s just like online setups, the only plus is no mass shipping fee. I quickly learned to ship live insects its not necessarily a cheap endeavor, not a surprise but I guess just something I didnt think about initially.
Will probably grow when this is all said and done with, just dipping my feet in at first.
Oh and you were right by the way, they dont need much space, they will find the moisture. I just make sure theres enough oatmeal as they travel through it as if its soil, almost as if the more I put in the container, the more moving room they have.
Not sure how often you should clean though, I guess it varies with how many you have. I buy 100 every 2 weeks and typically when(if) I have any left I take them out, clean the container, put them back with the new ones.
With the mealies, with their typically shorter lifespan, I like to keep the old ones seperate from the new. Call me crazy but it just has to do with possible die-offs as well as monitoring if any turn, as well as I like to know I am keeping a continuous rotation of the freshest worms. If you dont use the oldest first, then the oldest could just blend with the newest, and so on and so forth until death.
Ive been working at food plants for years so I guess product rotation is just burned into my skull at this point (haha)
