Best Terrarium Heat Mats of 2025

"I find this product works perfectly for my gecko. The lack of an on/off switch is alright for my setup, but if you need adjustability, you might want to look elsewhere. Overall, it's functionally safe and durable."

"I purchased two of these for my 120-gallon tank for my bearded dragon. They keep her toasty warm, with a warm side around 100°F and a cool side at 80°F. She loves having the heat options!"

"After having issues with another brand, I switched to these UTHs. They are heavy-duty and use 3M heat-strength glue. They put out a lot of heat, but I learned the hard way that a thermostat is essential. These are as good as the top brands, if not better and cheaper!"

"I'm really pleased with my purchase. It gives me peace of mind knowing that my Pacman will remain at consistent temperatures. While the heat pad alone wasn't sufficient to raise the ambient temperature, I plugged a bulb into the thermostat instead. It works as intended and feels heavy-duty and high quality. Plus, it's super easy to use!"

"I bought this heater for my Whites Tree Frog and I'm thrilled with the results. It maintains an even temperature effortlessly. The digital display and control buttons make it really user-friendly. Just set it and forget it; I don’t have to worry about it getting too hot or not hot enough. Definitely worth the investment!"

"Upon opening the package, I noticed some issues. The adhesive wasn't properly attached to the heat mat in several areas, making it hard to stick to the tank. I had to improvise with aluminum tape since my crab needed warmth urgently. While the heat works fine, there seems to be a manufacturing flaw with the adhesive, causing uneven heat distribution."

"I noticed the temperature dropping after a couple of weeks. Upon inspection, the heating pad was inflated like a balloon. I’m really disappointed as I paid a good amount for a product that’s now non-functional and potentially dangerous. I wish I could get a refund. Be cautious if you’re considering this purchase!"

"I really enjoy using this product during winter to keep my toads warm, particularly in their bath. Living in a cold area, I've found it helpful for monitoring my terrarium's temperature. I set it around 73-75 degrees, and it works perfectly, allowing my toads to move if it gets too warm."

"As a hermit crab owner, I faced challenges maintaining the right temperature in my 55-gallon tank. After trying this heater, I found it effective in providing consistent heat, though I recommend pairing it with additional heating for larger tanks. Overall, it's a reliable choice for creating a safe environment."

"I appreciate how effective this heating pad is for my ball python. I already had one for six months and just got another for my new snake. Very happy with the product!"

"For my hermit crab tank, these pads are fantastic! They’re sturdy, not flimsy at all, and provide just the right amount of heat. I wish they had a temperature dial, but they’re definitely worth the investment!"

"I use this heating pad under my hamster's cage. It keeps her warm without overheating. I noticed she moved her bedding away from it, which is interesting. The plastic base has warped a bit, but it’s still in good condition. I’m glad I can easily remove it when needed!"

"This 5W reptile heat pad was just what I needed for my snake this winter. It fits perfectly underneath the glass of my terrarium. It's not too hot, and since it's under the tank, I feel more secure about the risk of burning her. The quality seems good, and for this price, it’s a no-brainer for a small heat mat for my reptile!"

"I found this heat pad to be very compact and lightweight and it puts out just the right amount of heat. I recommend using it with a control system that has dimmable heat. With its quick and even heating, it ensures a comfortable habitat for my reptiles. Installation is a breeze as it’s so thin; I just placed it under the tank. The 5-foot power cord makes it easy to reach a wall socket. It’s the perfect size and will never exceed 122 degrees. I'm planning a second frog tank, and this will be a crucial component!"

"I wasn't sure what to expect, but honestly, this just doesn't seem to give off much heat."

"I didn't utilize the adhesion feature since I was using it for a homemade incubator for my baby sugar glider joeys. I was worried about it heating sufficiently through the thick fabric and fleece, but it gets very hot! After running nearly 100% continuously for 2 months, it has worked perfectly. I will definitely purchase from this brand again."

"I've only been using this for about 24 hours, but I’m pleased so far. The red LED display is bright and sharp, and I easily set the temperature. My seed starting table is in a cooler basement, and the mat has brought my soil temperature up to around 80°F. It's capable of higher temperatures, but I don’t need that right now."

"I replaced an older heat mat with this VivoSun model for my orchid terrarium. Unfortunately, it barely gets warm to the touch. After setting it for 80°, it only reached 68°F. I tried plugging it directly into the wall, bypassing the thermostat, but it didn’t work. I must have received a defective unit."

"I find this heat mat works well and stays on the tank, keeping my scorpion warm."

"Initially, I was hesitant, but this heat mat turned out to be much better than the previous ones I used. The adhesive is great, and it heats evenly."

"I've always used Exo Terra heat mats for my snakes, and they never disappoint. The adhesive is extremely strong, and they last a long time without needing replacements."

"This is my favorite heating pad for my tarantulas! It's easy to stick on and use, has good thick quality, and has never gotten too hot. I love that it works on acrylic enclosures without any melting."

"I got a larger tank for my hermit crabs, and this heating pad seems to be at a perfect temperature! They are obviously loving it, and I'm excited to keep upgrading their new enclosure!"

"I really wanted to love this product. It worked great for us for almost a year, but the adhesive began to peel off around the outer edge shortly after applying. Despite that, it never shifted enough to cause issues, and the heating function was reliable."

"I was pleasantly surprised by how easy to use this thermostat is. It exceeded my expectations and is perfect for my scorpion!"

"I’ve had great success with this heat pad. It’s the perfect size for my needs, and my crickets are thriving. Thank you, Henriette!"

"Overall, I’ve used several of these heating pads. They work well, but the programming can be a little quirky. Still, it’s not a major issue."

"I love the thermostat dial to easily adjust the temperature!"

"Initially, I was impressed with the thermometer. However, after setting it up in my ball python habitat, the glass shelf shattered from the heat and the heating pad started smoldering. I didn’t contact the seller, but I realized I was taking a risk. Just be aware of potential issues!"

"Using this heating pad for blending color pencil work and warming seedlings has been great. The adjustability is perfect for my needs. I had to use white-out to mark the dial since it has no markings, but overall, it works well without any problems."
