Hermit Crab Heat Lamp: The Importance of Keeping the Right Temperature for Hermit Crabs

Hermit crabs do not need a heat lamp to live a healthy and happy life. Providing a warm environment but avoiding overheating your hermit crab is the best way. If you decide to use a heat lamp, place it in an area where the crab cannot escape, like under furniture. Check on your hermit crab daily to ensure they are safe and comfortable. 

Keeping hermit crabs healthy and comfortable is essential for their longevity. One of the most common problems is the hermit crab getting too warm or too cold, which can lead to health issues and even death.

The Ideal Temperature for Hermit Crabs

Keep the tank at about 75-85 degrees Fahrenheit, and they will be happy! – Hermit crabs need a slightly more humid temperature to be comfortable.

It is important to remember that hermit crabs are tropical creatures and thus require a different level of heat than tanks in colder climates. Therefore, hermit crabs living in warmer climates will suffer heatstroke if their enclosure temperature is too high. 

You’ll need to consider their natural habitat and environmental conditions to find the ideal temperature for hermit crabs.

Checking Your Crab’s Enclosure Temperature

To ensure their well-being, it’s essential to check the temperatures in the crab enclosure regularly. Don’t let the temperature go below 75 degrees, or they’ll become sick. Keep an eye on them every few days to make any necessary adjustments as needed.

How to Tell if a Hermit Crab Is Getting Too Hot in Its Tank

To gauge the temperature of your hermit crab’s tank, you can use a thermometer or feel the tank to see if it’s too hot to the touch. If it feels too hot, moving your hermit crab to a more relaxed place may be time. 

Benefits of a Hermit Crab Heat Lamp

A hermit crab heat lamp is a great way to keep your crab warm and comfortable. It can also be used to simulate natural light, improve the health of your crabs by providing them with enough Vitamin D, and help keep the environment cool.

Methods for Heating Your Crabitat

Hermit crabs need heat to survive; the best way to provide it is by using a heat lamp. If you don’t have access to an electrical outlet, you can use a few methods to heat your crabitat. 

One is to use a portable heater. Another is to set up a hot water bottle on the floor of the crabitat. Another common way is to use an electric heating pad. Choosing the best heating method for your hermit crab will ensure their safety and comfort.

Under-Tank Heaters AKA Heat Pads

These heaters are placed underneath your crabitat and provide hermit crabs with a constant source of warmth. They come in different sizes to accommodate different-sized tanks, so there’s no need to worry about finding one that fits. Installation is easy – plug it in, and you’re ready!


Insulation is one of the most critical aspects of crabitat heating and humidity control. Therefore, it is essential to choose the suitable material, install it correctly, and ensure it stays in place.

There are a variety of materials you can use for insulation – wood, fiberglass, rock wool, etcetera. It is also essential to ensure that the insulation (whether natural or artificial) is installed evenly throughout your crabitat to achieve optimal heat transfer and prevent mold growth.


Using energy-efficient LED lights is the best option for hermit crabs that like to hide under rocks or in other shady areas. These bulbs produce excellent light, which is perfect for invertebrates as it doesn’t scare them away. 

You can also use incandescent bulbs, but they give off a harsh light which might make your crabitat inhabitants shy away from the area. Fluorescent tubes are the most popular heat source for hermit crabs – they emit a warm light ideal for those who want an even temperature throughout their enclosure.

Multi-Fixture Hoods

Multi-fixture hoods are an excellent option for hermit crabs as they can be adjusted to different angles and have a built-in heater. They’re also perfect for use with salt water tanks, as the heaters ensure that the tank is always at the correct temperature! 

You can find multi-fixture hoods in various lengths – long, medium, and short. It also has a variety of accessories, like heat lamps that clip onto the hood. Plus, it’s easy to install – plug it in!

Ceramic Heat Emitter

A ceramic heat emitter is a great way to heat your hermit crab’s enclosure. It emits infrared radiation, which reaches the crabitat in minutes, making it convenient for quick and easy heating. You can also place the heater on the enclosure’s floor or attach it to the wall.

Thermostats and Rheostats

There are several ways to heat your crabitat: thermostats or rheostats. Regarding heating, getting the right appliance can make all the difference for you and your tank’s inhabitants. So if you’re looking for an adjustable heat lamp that will help regulate your tank’s temperature effectively, get one of these! 

Make sure also to choose the right type of heating system for your crabitat and its inhabitants; this way, everybody will be comfortable at all times. Alternatively, consider using a rheostat if you want something less hands-on but equally practical.

Ways to Keep Hermit Crabs Warm Without a Heater

Hand Warmers

Small heat packs can be placed around the crab’s habitat. These packs are easily hidden and provide enough warmth for crabs during cooler months.

Move Them to a Warmer Area

Try moving them to a warmer area using one of the following methods: Use an oven on the lowest setting to warm up their home slowly. Place them outside on sunny days where they can gradually get used to warmer weather.

Run a Humidifier

A humidifier is a great way to keep hermit crabs warm without using a heater. It’s also ideal for people with dry skin or sensitive noses, as the humidity in the air provides relief. 

To buy an automatic humidifier, you must decide on your budget and what type of hermit crab you have. For manual ones, ensure the water reservoir is big enough so the hermits can move around and wet their shells. You can add some fresh fruit or veg to make it more appealing to them; this will help keep them healthy and happy!

Insulate the Enclosure

One way to insulate the container is by adding newspaper, cardboard, or fabric layers. This will help reduce humidity levels and potential health concerns related to too much moisture accumulation inside an enclosed space like this one.

Add More Substrate

Hermit crabs like to hide and are happiest when they have plenty of substrates to play on. If your hermit crab isn’t getting enough substrate (or if their habitat has been moved), add some moistened sponges or moss directly to their tank.

Don’t Use Heating Rocks

Heating rocks are a popular way to provide heat for your hermit crab, but they’re not the best option. Heating rocks can be dangerous and can lead to overheating your pet. Instead, use an electronic heating pad or a special hermit crab tank. These devices will help keep your hermit crab safe and warm while providing the gentle warmth they need.
