Advertisement I think you can use those vacuum sucking cups too, but I'm not sure how well they'll stay when there is warmth involved, or how well they stick to woodlike surfaces. I have no experience with heat tape, from what I've gathered, that stuff is the same material and build as the heatmats they use for reptiles, those awful sticky things that get like 60°C or something. The cable I use is only 25 watt at a length of 25 meters. For my hissers and the feeder dubia I use a heatmat that is non stick and gets only 40°C. I use this partly for my snake, on one side, and partly for the hissers on the other side. If you use either, make sure to leave a gap of 2 to 3 cm to prevent overheating your animals. Spiders are not as smart as reptiles and fry themselves. With these lower temperatures, literal burning is not a possibility, but still, I don't have anything directly on either cable or mat.
