Hi
I use a ten gallon tall tank and have a screen lid for it. I usually order my crickets from a cricket farm/supplier. I empty the crickets into the tank and I keep the egg carton packaging that comes in with the crickets. I tear the cartons into the certain sizes I want and make a climbing area on both sides of the tank with them and I will put food and water in the middle or at the front. I put cricket food or bran in a jar lid, and I also have three or four other jar lids that I will put cotton balls into and then fill those caps with water and that way the crickets have something to climb on and won't drowned and it works great.
On the top of the egg cartons that I have built up for the crickets I will put some monkey chow things in some of the gullies of the egg cartons and then put an empty toilet paper roll over the top of them. When it comes time to get some crickets out, I will hold the tall plastic bag in the tank and pick up the toilet paper rolls one at a time and shake them into the plastic bag, until I have the quantity of crickets I need and it works great for me.
I usually order 2 to 3,000 crickets at a time, the half inch size ones or the three quarter inch size ones. Yes, I have a lot of L. Geckos, they are addicting. I have seventeen of them.
Sincerely, TLB
