A lot of the youtube videos I've seen about raising crickets go too far overboard..... IMO. The best information I found that got me moving in the right direction is this http://www.wormman.com/breeding_crickets.cfm

My garage temps range from less than 32F (0C) to 100F (38C). I find about 90F (32C) keeps their breeding and life cycle on schedule and predictable. I cut some 1/2in (13cm) foam board into six pieces to form a box around all the containers. There are two flourescent shop light fixtures that hang inside and the heat they produce is more than enough to keep the temps up on the coldest of days. The crickets don't need light from my understanding, but I do... The fixtures where already there as I used to start seeds for the garden on that shelf. I manage the temperature by removing or adding the sides of the foam box or by turning on or off one or both sets of lights.

For containers, I use these.... https://www.walmart.com/ip/Sterilite...7DrXF3DltMbX4s
I don't put any bedding material or substrate in the bins. That just hides potential issues. I leave the bottoms bare, but I do rough them up with sandpaper so the crickets can crawl on it. Otherwise it's so slippery I imagine they'd get stressed.

I also replace the tops with some frames I made to fit that have window screen in them to give them plenty of ventilation. Otherwise they get to stinking pretty quick. It's not something you want to do in your home which I guess is why a lot of the youtubers were going to extreme lengths to design ventilation systems and cutting holes in their bins.

I use the water crystals to provide water. There are some that feel they are certain death for your frogs, but I've not had any issues in the six or seven years I've been using them. And if I have a surplus of alternate water sources such as citrus peels that still have some flesh on them or potato slices, then I may switch to that when the bin is feeder size.

Making new crickets is as simple as putting a shallow container of moist soil or similar (I use Eco Earth) in the bin for a few days when the bin reaches breeder size. For me this is after they pass feeder size and is just before they naturally die. I leave the container in there as little as 36 hours and sometimes up to five days. Temperature seems to dictate how active they are laying eggs.

Although I do tend to them every other day, I have left on vacation for two weeks and the only issue was my breeding schedule was interrupted and I had to buy some to have feeder size crickets for my frogs.

After they've laid eggs, they all get dumped in a large bucket I keep for things destined for the compost pile and sprayed with a pyrethrin type poison. What I'm currently using is this http://www.homedepot.com/p/Hot-Shot-...6190/203842329
which is a Lambda-cyhalothrin, a synthetic pyrethroid that I don't have any issue with.

The dead crickets, their litter, eggcrate and everything else in their bin goes in the compost pile.
