What do you guys use for a heating source?

I bought a medium sized zoo med under tank heater on amazon and a infrared thermometer gun so we'll see how hot it gets. I have a 22 gallon rubbermaid bin setup to buy some dubias, I just need to make sure the temps are right. People recommend if you're going to use a heat mat that you buy a rheostat or thermostat to regulate heat (I'm not going to, I want it to get pretty hot so I don't care as long as it doesn't get out of control). If you can find a heat mat at any pharmacy store, Walgreens, etc. that is 24 hours without shutting off then that's a good buy too that gets up to around 100-105F. Preferably use a surge protector as well to prevent voltage spikes while it is left on 24 hours hours at a time. Flukers makes these heat mats that heat at a constant 100F and can be used inside of the enclosure laying on the bottom, etc. You want to heat the side with all the egg flats and the side with the food leave the heat mats off of so the roaches can cool off. The heat mats over there egg flats will allow them to thermoregulate and breed without problems as long as the bottom is around 90-95, preferably 92-95 will really get them going. Some people use nocturnal bulbs as a heat source hanging over the ventilated part into the bin, but that's a little inconvenient compared to heat mats.
