1. Why Humidity and Temperature Matter
The temperature and humidity in your spider’s environment are crucial to its health, affecting everything from its behavior to its ability to molt successfully. Jumping spiders come from a variety of habitats, including tropical rainforests, dry savannas, and even arid deserts. Although they are adaptable, providing the proper conditions will help your spider thrive, stay hydrated, and remain active.
The Impact of Temperature and Humidity on Jumping Spiders:
- Metabolism: Temperature directly influences your spider’s metabolism. Too cold, and your spider will become sluggish; too hot, and it may become stressed or even lethargic.
- Hydration and Molting: Humidity is essential for maintaining proper hydration. It also plays a vital role during molting, as a higher humidity level helps the spider shed its exoskeleton more easily.
- Behavior: A comfortable environment promotes active and curious behavior, while an uncomfortable one might cause your spider to hide, become less active, or even refuse food.
2. Ideal Temperature Range
Temperature is one of the most important factors for keeping your jumping spider healthy. In their natural habitat, jumping spiders tend to live in warm environments with stable temperatures.
Recommended Temperature Range:
| Temperature (°F) | Temperature (°C) | Effect on Spider |
|---|---|---|
| 72°F - 78°F | 22°C - 26°C | Ideal range for normal activity, health, and digestion |
| Above 80°F | Above 27°C | Stressful; may cause lethargy, loss of appetite, and overall discomfort |
| Below 65°F | Below 18°C | Cold-stressed; the spider may become lethargic, stop eating, or refuse to move |
- Too Hot? If your spider’s enclosure becomes too warm (over 80°F or 27°C), it can become stressed. Signs of heat stress include lethargy, refusal to eat, or your spider constantly seeking cooler areas in the tank.
- Too Cold? When temperatures dip below 65°F (18°C), your spider can become sluggish and may refuse food or water. Prolonged exposure to cold temperatures could even slow down its growth or delay molting.
How to Maintain Ideal Temperature:
- Heat Mats: If you live in a cooler climate, consider using a heat mat to maintain the desired temperature. Make sure the mat covers only one side of the enclosure to give your spider the option of finding cooler areas.
- Ambient Temperature: Keep your spider’s enclosure in a room where the temperature is stable. Avoid placing it in direct sunlight or near drafts, as sudden temperature changes can stress your spider.
3. The Right Humidity Level for Jumping Spiders
Jumping spiders thrive in environments with moderate humidity. Too much moisture can lead to mold and mildew, while too little moisture can cause dehydration and difficulty during molting.
Ideal Humidity Range:
| Humidity (%) | Effect on Spider |
|---|---|
| 50% - 60% | Ideal for healthy hydration, proper molting, and behavior |
| Below 40% | Dehydration risk; spider may appear lethargic or refuse food |
| Above 70% | Excess moisture; can lead to mold growth and potential respiratory issues |
- Why Humidity Matters: Jumping spiders rely on humidity for proper hydration and to aid in molting. A lack of humidity can result in dehydration, which weakens your spider’s immune system and may prevent it from eating or molting properly.
- Signs of Low Humidity: If your spider is sluggish, refuses food, or is struggling during a molt, it could be a sign that humidity is too low.
- Signs of High Humidity: If you notice condensation inside the enclosure, or if mold or mildew begins to grow, the humidity is too high.
How to Measure Humidity:
To effectively monitor the humidity levels, you will need the right tools.
- Hygrometer: This tool measures the humidity in the enclosure. Look for a digital hygrometer with an accurate range (50%-60% is ideal).
- Thermometers: Make sure to measure both temperature and humidity regularly using a thermometer or a combined temperature-humidity gauge.
4. Setting Up the Enclosure for Proper Humidity and Temperature
Now that you know the ideal temperature and humidity ranges, let’s talk about how to create an environment that maintains these conditions.
Choosing the Right Enclosure
Jumping spiders do well in small to medium-sized glass enclosures or terrariums. Make sure the tank has good ventilation (air holes or mesh tops) to ensure airflow, as stagnant air can lead to mold or high humidity levels.
Tips for Choosing the Right Enclosure:
- Size: A 5-10 gallon tank is suitable for most jumping spiders. Make sure it’s tall enough to allow vertical movement, as these spiders like to climb.
- Ventilation: Ensure the tank has enough ventilation holes to allow air circulation but avoid excessive gaps where your spider could escape.
Maintaining Temperature and Humidity:
- Heat Mats: Place a heat mat underneath or on one side of the enclosure to maintain temperature. Avoid placing it on the bottom of the tank if you want to prevent overheating the substrate.
- Water Dish: Include a small, shallow dish of water. This will help increase the humidity, but be sure to refill it frequently and clean it to prevent bacteria buildup.
- Mist the Tank: Light misting helps increase humidity. Be cautious not to overdo it; misting once every few days is typically enough. Avoid soaking the tank or substrate.
5. Substrate and Humidity Control
Your choice of substrate plays an important role in humidity regulation. Substrates that retain moisture without becoming overly damp are ideal.
Recommended Substrates for Humidity Control:
| Substrate | Benefits | How to Use |
|---|---|---|
| Coco Fiber | Retains moisture well and provides a natural environment | Mist lightly to maintain moisture |
| Sphagnum Moss | Excellent at holding moisture and promoting humidity | Keep lightly moist, replace as needed |
| Peat Moss | Good moisture retention; maintains humidity | Mist regularly, avoid oversaturation |
Tips for Maintaining Substrate Moisture:
- Avoid Soggy Substrate: Too much moisture can lead to mold or rot, so always aim for damp, not soaking wet, substrate.
- Replace Regularly: Over time, substrates like moss or coco fiber may lose their moisture-retaining capacity. Replace the substrate every 4-6 months.
6. Signs of Incorrect Humidity and Temperature
While jumping spiders are quite resilient, improper humidity or temperature can lead to health issues. Here are some common signs that something’s off in the environment:
| Issue | Possible Cause | Signs | Solution |
|---|---|---|---|
| Lethargy | Too cold or too hot | Inactive, refuses food | Adjust temperature to 72°F - 78°F |
| Refusing to Eat | Dehydration due to low humidity or stress | Spider avoids food | Increase humidity to 50%-60% |
| Molting Issues | Insufficient humidity for proper shedding | Struggling during molt, incomplete molt | Increase humidity and ensure proper temperature |
| Mold Growth | High humidity or poor ventilation | Fungal growth on substrate or walls | Reduce humidity and improve airflow |
7. Adjusting for Seasonal Changes
As the seasons change, you may need to adjust the temperature and humidity in your spider's enclosure to keep things comfortable.
Winter Adjustments:
- Heat Mat: You may need a heat mat to maintain the appropriate temperature in cooler months. Make sure the heat mat is not too strong to avoid overheating.
- Humidity: Indoor heating can dry the air, so you might need to increase humidity by misting the enclosure more frequently.
Summer Adjustments:
- Cooler Areas: During hot months, make sure the enclosure is not in direct sunlight or near heat sources.
- Humidity: If the environment becomes too dry, consider using a humidifier or more frequent misting.
8. Conclusion
Maintaining the right temperature and humidity is crucial for the health and happiness of your jumping spider. By providing a stable environment with the proper range of temperature (72°F - 78°F) and humidity (50%-60%), you'll ensure your spider thrives and remains active. Regular monitoring, proper substrates, and seasonal adjustments will help create the best habitat for your arachnid friend.
