What type of additional heating is required for my tarantula in cold environments?
If the location where your tarantula is kept gets below 60F (50F for the Aphonopelma genus) consistently then you will need to have additional heating. A small space heater will work. Good results can also be achieved using one of the flat reptile heat pads mounted to the bottom of the tarantulas habitat. Mount the pad at one end so that if the tarantula gets too warm it can move to the other end where it’s cooler. Building a spider closet, heat and humidity regulated, is also an option if you have several requiring environmental control.
