How can I keep my tarantula healthy when I’m out of the house?
Check the enclosure temperature at 8am and keep it between 72–82°F (22–28°C). A simple schedule of daily, weekly, and monthly tasks lets you maintain humidity, feed safely, and spot problems without constant handling.
Daily routine you can actually keep
At 8am pull the digital thermometer out of its slot and record the reading; if it falls below 72°F (22°C) turn the 25‑watt heat mat on for 10minutes. Next, swing a hygrometer into the enclosure and adjust the misting bottle until the humidity sits between 40% and 80% depending on your species. Feed 2–3 appropriately sized insects (crickets no larger than 1in per 4in legspan) and watch for the spider to seize within 30seconds; if it doesn’t, remove the prey to avoid stress.
Around noon, skim the water dish and add fresh dechlorinated water to keep about 1oz (30ml) available. Spot‑clean any shed exoskeleton fragments with a soft brush, being careful not to disturb the burrow. Take a quick photo or note any discoloration on the substrate, which can signal excess moisture.
At 7pm give the enclosure a final glance: verify the temperature still reads above 72°F, re‑mist if humidity has dropped below the lower bound, and reset the heat mat timer for the night if needed. Log the day’s numbers in a notebook or phone app so trends become visible. Close the lid securely and turn off any supplemental lighting.
- 8am – temperature check, heat mat if needed
- 8:15am – humidity check, mist to target range
- 9am – feed 2–3 insects, observe capture
- 12pm – refresh water, spot‑clean debris
- 7pm – final temperature/humidity check, log data
Weekly layer: deeper cleaning and inventory
Choose a consistent day, such as Saturday, to replace the top 1‑inch layer of substrate with fresh coconut fiber or peat. This prevents mold buildup while keeping the burrow depth at a healthy 2–3inches for a 12‑gallon (45‑L) enclosure. After the substrate shift, spray the entire interior lightly and let it dry for 15minutes before resealing the lid.
Run a quick audit of your feeder insects: count how many crickets, roaches, or mealworms you have left, and order more if the total drops below 20units. Rotate the feeder containers so the oldest insects are used first, reducing the risk of accidental over‑feeding. Finally, test the hygrometer battery and replace it if the display flickers; a faulty sensor can mislead you about humidity levels.
- Replace top 1‑inch substrate layer
- Audit feeder inventory; keep ≥20 insects
- Check hygrometer battery and replace if needed
Monthly maintenance for long‑term stability
On the first weekend of each month, empty the entire enclosure, dump the old substrate, and wash the glass with a diluted vinegar solution (1part vinegar to 4parts water). Rinse thoroughly and dry with a lint‑free cloth before adding 3inches of fresh substrate. Re‑position décor like cork bark or PVC tubes, checking for cracks that could harbor pests.
Inspect all electrical equipment: verify the heat mat’s resistance with a multimeter, replace any frayed cords, and consider swapping a 25‑watt mat for a 30‑watt one if the enclosure consistently reads below 72°F. Clean the water dish with a soft sponge and replace it if any biofilm appears. Record the month’s temperature and humidity averages; a drift of more than 5°F or 10% signals a calibration issue.
- Full substrate change (3inches deep)
- Clean glass with 1:4 vinegar solution
- Test and replace heat mat if needed
When time is tight: what you can skip safely
If a work trip leaves you with only a few hours, focus on the three non‑negotiables: temperature check, humidity adjustment, and water refresh. Skip the midday spot‑clean; a single night’s debris rarely harms a healthy tarantula. You can also postpone the weekly substrate top‑layer replacement for up to two weeks without affecting molting success.
On a day when you’re running late, feed the spider the night before and give it a full 24‑hour fast; most species tolerate a week without food as long as they’re not in a pre‑molting phase. Keep a spare hygrometer in a drawer so you don’t waste time searching for it. By concentrating on the core climate parameters, you maintain a stable environment even during brief absences.
- Never skip temperature or humidity checks
- Water dish must be refreshed daily
- Spot‑clean can be delayed up to 48hours

Related questions
How often should I mist my tarantula’s enclosure?
Mist once in the morning and once in the evening, aiming for a humidity range of 40–80% depending on species. If the hygrometer reads below the lower bound, add a quick spray until the target is reached.
What size enclosure do I need for a 6‑inch legspan tarantula?
A minimum floor area of 12×12inches (30×30cm) and a volume of about 10gallons (38L) works well. Provide 2–3inches of deep substrate for burrowing.
Can I feed my tarantula live insects every day?
No. Feed 2–3 appropriately sized insects every 5–7days; over‑feeding can lead to obesity and waste. Adjust the amount if the spider is pre‑molting or if you notice leftover prey.
