no problem at all. lets start off with the extra small size I have of the Black Solider Fly Grubs (Reptiworms).
What you will want to do is put them in a plastic container of some sort. you can get them at walmart. It doenst need to be very big. Just something to hold twice the size of the worms (but remember they will grow)
You will want to feed them a corn meal mash. you can get it at your grocery store. You will want to mix 1 part water to 1 part meal. It will be the consistency of mashed potatoes almost. You will want to put the worms in with the same amount of food. So lets say you have 1" deep of worms you will put in 1" of food. This is done about twice a week. You can tell when they need new food as the worms will turn the mash black. Also the bottom of the plastic container will be very hot from bio-waste. Each time you change the food you will want to sift the worms and throw away the waste (or use it in your garden as its a very good fertilizer). That is pretty much all that is needed to make them grow. Please note that they can grow very fast if you feed them a lot and they create a large amount of ammonia so make sure you do it in a well ventilated place. I would also suggest doing it at room temperature. Once you get the worms to the size you want you will want to remove them from the food and you can cool them down in a wine fridge (50-60 degrees F). they can last for over a month in a wine fridge. At room temp. they can last 2-3 weeks without needing any food.
I do sell the extra small on the website (
www.Reptiworms.com).
Let me know if you have any questions.
Thanks!
